13 Sites with Free CAD Blocks

Updated May 22, 2022

Whether you’re a CAD hobbyist or a professional, you’ll know that creating 2D and 3D designs can often be a time-consuming process. Those who are keen on increasing their productivity and creating quality designs often make use of CAD blocks. Blocks are a collection of vector designs grouped together to form a single entity. They are often used in AutoCAD, but can be compatible with other software. Not sure where to look for free CAD block downloads? Don’t worry: as always, the Scan2CAD team is here to help.

We’ve put together a list of 13 websites that offer free CAD blocks so you don’t have to fork out a single penny! Our options span popular CAD software such as AutoCAD and SketchUp, and fields including architecture and interior design. With such choice on offer, you’re sure to find something that will suit your needs! You can also used these free CAD blocks using the range of free CAD software that’s available.

13 Sites with Free CAD Blocks

1. Cad-blocks.net

We’ll start our list with cad-blocks.net. With this site, what you see is what you get. While the site itself isn’t that sleek or modern, it doesn’t take away from how useful it is as a resource for free blocks. So, what’s on offer? Thousands of DWG files for use in AutoCAD and other popular architecture. Knowing that compatibility can be an issue for users with older software versions, cad-blocks has made it clear that all blocks are compatible with AutoCAD 2004 to the latest release.

Not only are the blocks here free to download, but another great advantage is that registration isn’t required. Blocks are sorted into collection categories that include furniture, vegetation, kitchen equipment, and signals, amongst many others. When you select a collection, e.g., vegetation, you’ll be met with further sub-sections like color trees, trees elevation, and so on. If you like the look of tree plan CAD blocks, for example, it’s as simple as clicking “download”. Then, in no time at all, you’ll have 427 CAD blocks at your disposal.

It’s safe to say that, given the thorough nature of cad-blocks, you’ll find something that catches your fancy. And, with its handy previews, you can see everything on offer with each block download without having to wait until you actually download.

2. Cad-block.com

Next on our list is the similarly named cad-block.com. This resource offers architects, engineers and designers a way to find new and high-quality projects and models. We’d like to remind users, however, that many of the sites on our list—cad-block.com included—contain blocks that are uploaded by other users. This means you might encounter issues with varying units, scales and so on. To work with the blocks on offer, cad-block recommends you use AutoCAD 2007 and later. If using an earlier version of AutoCAD, you may experience issues with file compatibility. As with the previous entry on our list, you don’t have to make an account to take advantage of what’s on offer here.

Cad-block offers a wide variety of free blocks and premium blocks (which as the name suggests, come with a price tag). At the top of the page, you’ll be able to select CAD Blocks or Premium Models. If you’re not interested in paying, CAD Blocks is your destination. Be aware, however, that the page includes free and paid blocks. There’s no way to filter it to only show free CAD block downloads. Fortunately, if the block comes with a price, there will be a bright green tag in the corner. The list on right allows you to sort through categories, from appliances to interiors to lighting. It couldn’t be simpler to download—one click and you’re ready to go.

While it’s slightly annoying to have both free and paid blocks on the same page, we can’t find many other faults with cad-block. We particularly like that, when you select a block collection to download, you’ll be able to see similar blocks and drawings underneath—previews and all. And, if you’re interested in joining a community, you’ll be pleased to hear that cad-block allows users to upload their own blocks and share with other users.

3. Cadblocksfree.com

Cadblocksfree.com is yet another online CAD library filled with a huge variety of both 2D and 3D models. As with our second pick, cadblocksfree comes with both free blocks and a selection of paid, premium models. For those interested in the paid block collections, they offer three membership plans that cover 1 month, 6 months and 12 months. If you don’t want to pay for a membership, that’s fine—you don’t even need to register to download any of the models.

The site firmly separates 2D and 3D models into two different pages. If you head to either page, you can look at only free blocks by selecting $0.00-$0.00 from the filter options. There’s a lot on offer here, with 1,828 free 2D blocks and 3,483 free 3D blocks. As with other sites offering blocks, cadblocksfree has a category list on the left-hand side that includes categories like doors, furniture and transport. If you select a category, e.g., architectural, you’ll be met with further subcategories like fireplaces or fences. All blocks on offer will be available in a preview before you so much as select them. And once one’s caught your eye, you’ll have it downloaded in a couple of mere clicks.

If you like creating your own blocks, you’ll be pleased to know that cadblocksfree gives users the opportunity to upload and even sell their own models. You will, of course, have to set up your own account to so. And that’s not all. The site also comes with its own forum, where users can discuss and share AutoCAD tips and tricks!

4. Cad-blocks.co.uk

Screenshot of cadblocks homepage

If you’re not interested in forking out a single penny for blocks, you’ll be pleased to find that cad-blocks.co.uk offers only free CAD blocks. That means you don’t have to bother having to filter between paid and free blocks. What’s more, registration isn’t required—you could be downloading CAD blocks in mere seconds. All blocks available on site are in AutoCAD 2000 format, so compatibility shouldn’t be a problem. They have all been processed to ensure they’re free from errors and where possible, all CAD data is to scale.

To start off your journey into free CAD block downloads, all you’ve got to do is head to the Downloads page. By default, you’ll be brought straight to the first category—Aircraft. From the carousel at the top, however, you can browse through all other categories on offer, from road signs to building elements to drawing symbols. Each category contains previews of the blocks on offer. If you’re interested in one, simply click on it and you’ll be sent to a page where you can directly download it. Overall, there appears to be a decent selection of various blocks.

For those that are looking for something more, cad-blocks has the perfect offer: you can download the site’s entire block collection for £19.99. All you’ve got to do is provide an email address and a one-off payment of £19.99, and you’ll gain access to 3,111 blocks! Now, that’s a tempting offer!

5. BIMobject

Screenshot of BIMobject object list

Our next choice is slightly different to those mentioned so far in that, while it has a large collection of 2D models, BIMobject mainly specializes in 3D objects. A particularly noteworthy mention is that these 3D objects are available in a range of formats including Revit, Allplan and 3DS. Unlike the sites listed above, BIM Object does require you to set up an account in order to start taking advantage of what’s on offer. However, with 327,383 parametric BIM objects and 27,865,027 products available, there are plenty of reasons to sign up!

Even at a quick glance, it’s clear that BIM Object is different to the rest—its site is sleek and accessible. With such a large collection on offer, however, it will take you a while to filter through everything to find what you’re looking for. To start, you’ll see small logos at the top to help you navigate straight to category pages ranging from construction to electronics to signage. Additionally, you’ll be able to filter products via brands, BIM object categories and file types. Each category comes with further subcategories, e.g. construction > access doors and panels. From there, you can look through previews of each block. Once you’re a member, you’ll be able to download at the click of a few buttons.

The site offers BIMobject apps for SketchUp, Revit, ARCHICAD and AutoCAD. The apps integrate the BIMobject Cloud into your chosen software so you can browse, filter and download objects into your project without switching between browsers. If you’re looking to speed up your workflow, it’s certainly worth considering.

6. Bibliocad

Screenshot of Bibliocad library

Our next choice is Bibliocad—a site that offers CAD and BIM resources for architecture, design and construction. As with the last few sites we’ve mentioned, the site offers a range of both free and paid blocks. In order to download anything from the site, you will have to register. There are two subscription plans on offer: a free account or a premium one. With the free account, you’ll be limited to free files only and up to 20 downloads per day. With a premium account, however, you’ll get premium files and up to 200 downloads per day! If you’re going to be using the site frequently, it’s certainly worth pursuing the Premium account.

There’s definitely a wide range of file types available on Bibliocad—including PAT, PSM, RVT, MAX and DWG. The library itself has 114,536 blocks. Unfortunately, as with cad-block.com, both paid and free blocks are displayed on the same page. You’ll be able to tell the difference between the two, however, because free blocks have a bright green flag in the bottom left-hand corner. When scouring your way through the library, you’ll be able to take advantage of the categories list on the left-hand side, including bathrooms, calculations, electronic and furniture. The only filter options available are most viewed, most recent, relevance and most downloaded.

With the lack of filter option for free/paid blocks, it might take you a little while to make you through all that Bibliocad has to offer. An issue many users have struggled with previously is that many of the blocks available have been submitted by various providers—while each block is processed, there can still be major differences in format, scale and units.

7. Cad-corner

Screenshot of example block from cad-corner

At first glance, cad-corner looks far more basic than all sites listed so far. While the site is extremely simple in design, that doesn’t mean you should discount it from your new list of block resources. Indeed, the site provides a wide variety of AutoCAD blocks that will take your designs to the next level. All blocks provided have been created or updated with AutoCAD 2006. So, if you’re using an earlier version of AutoCAD, they recommend downloading the Autodesk Batch converter or SolidWorks DWGgateway to sort out compatibility issues.

The categories available are displayed in a very simple list—so, you won’t have much trouble trying to locate what you’re looking for. The list includes architectural blocks, mechanical blocks and miscellaneous. If you select a category, e.g., mechanical blocks, you’ll see further subcategories like flow charts. Once you select a subcategory, you’ll have a list of available blocks to download. Unfortunately, some blocks have previews and others don’t. So, essentially, you might not know what a block will look like until after you’ve downloaded it. 

Cad-corner certainly isn’t as accessible as other sites on offer—we’d definitely like to see a tile preview of all the blocks on offer. That being said, you don’t have to register in order to download anything, so it’s not like you’re losing out.

8. Draftsperson

Screenshot of draftsperson homepage

Draftsperson is very similar to cad-corner. In other words, it’s pretty basic. It’s set out in a similar format—offering lists of subcategories and pages instead of a more accessible search option. The site offers a nice variety of free blocks and symbols, all saved in an AutoCAD 2000 format. They’ve made it clear that each free CAD block download has been carefully screened for the educational stamp. And any blocks you do download are on layer 0, bylock or bylayer and insert at 0,0,0. Additionally, A PURGE and AUDIT have been run on each block.

To start, there are main categories which all have lists of relevant subcategories and pages—including fixtures, people and animals, and civil. When you click on a page, e.g., people and animal > animals, you’ll see a small selection of available blocks. Fortunately, they offer previews, so you know what you’re downloading. As soon as you see something you like, it’s as simple as clicking on the drawing to download. Then, you’ll get a zip folder containing your new DWG.

As with cad-corner, Draftsperson is basic—its collection isn’t as extensive as other resources we’ve listed. That being said, there are definitely a few diamonds hiding in the rough, so be sure to look through it thoroughly!

9. DWG Models

DWG Models offers a huge DWG file library for architects, designers, engineers and draftsmen. After looking at the previous two sites, you’ll be pleased to see DWG Models is much more modern and sleek with its site interface. The database contains drawings, assemblies, diagrams, symbols and much more. Needless to say, there’s something for everyone. All files on offer are compatible with an AutoCAD platform, so you don’t need to worry. You don’t even need to register—it’s that simple!

DWG Models has an entire page dedicated to free blocks—its premium models are available on the Buy page. You’ll find a nice range of categories listed on the left-hand side, ranging from architectural details to landscaping to urban planning. Some categories contain further subcategories, e.g., interiors > equipment. If you’re not sure a block is free, all you’ve got to do is look for the bright green label in the bottom left-hand corner labelled “free”. Once you’ve got a block in mind, all you’ve got to do is click download and you’re sorted!

While registration isn’t required, DWG Models does recommend signing up if you’re a frequent user. Having an account will give you the ability to view DWG files more easily. In all, there seems to be a lot to sift through. And if it’s not enough, you’ve always got the premium blocks to look at!

10. CADdetails

Screenshot of CADdetails homepage

CADdetails is on an entirely different level to the sites we’ve listed previously. Why? Because they offer manufacturer-specific building product information and content for AEC professionals. On the site, you’ll be able to find high-quality CAD drawings, 3D models and BIM files. Whilst all content is available for download free of charge, you will need to register in order to download anything. With access to thousands of design and planning documents for commercial and residential building projects, however, we’re sure taking a few minutes to register is worth it.

To start, you can head to either CAD drawings or BIM models. There, you’ll be able to use a category list on the left-hand side to sort through what’s on offer—from technical documents to site products to speciality products. Once you’ve selected a category, e.g., technical documents, you’ll gain access to further subcategories like specifications. You can then select a manufacturer—like AGF Manufacturing—after which, you’ll see a list of available blocks. Simply hover over an item to see a preview. Once you’re a registered user, you can download files in mere seconds.

With 51,814 drawings available in CAD drawings and 10,452 in BIM, it’s safe to say you’ll be quite busy trying to make your way through what’s on offer. We’re definitely fans of the category and filter options—it makes searching for relevant blocks that much easier. Additionally, the option to mark products as favorites for future reference is certainly advantageous.

11. Syncronia

Screenshot of Syncronia 3D models

Syncronia is much like CADdetails in that is far more specialist in what it offers—specifically targeting architecture and design professionals. It gives users the opportunity to download 3D models, BIM objects and 3D libraries of surfaces, catalogues and specifications. The site also lists models by suppliers and manufacturers, so it might take you a while to get to grips with finding blocks you’re interested in. If you work in architecture or interior design, however, the learning curve is most definitely worth it.

Syncronia works in collaboration with Autodesk, so it’s of no surprise to find free downloads in a variety of formats including Revit, 3DS Max and AutoCAD. There’s a nice variety of filter options available, including product category, manufacturers, file type and keyword. Additionally, you’ll find a category list on the left: from bathroom to installations to doors and windows. You can even specify texture! In order to download anything that’s caught your eye, however, you will need to register. This could work in your favor, as registering will enable you to create a profile and publish your own projects.

Syncronia is definitely on a whole different level—not only can you download 3D models, you can also look at catalogs, technical information, specifications and get in touch with manufacturers directly. And if you’re interested, they’ve got their own projects page and magazine.

12. Allcadblocks (formerly Boss888)

Screenshot of Boss888 homepage

The penultimate site on our list is Allcadblocks.com (formerly Boss888, now a Chinese website) a site that offers users a range of architectural and interior design blocks. All designs available on the site are saved in an AutoCAD 2000 format, so, compatibility shouldn’t be an issue for most users. Boss888 have made it clear that they frequently update their libraries with new designs, which is always a sign of a good resource. While you don’t have to register to download anything, it might be worth considering if you’re going to use it frequently.

As with other sites, there are both free and paid blocks on offer. There are 410 free CAD block downloads available. Bear in mind that these aren’t individual designs—they’re typically grouped together in collections, so you do get quite a lot. You can sort through the free collection by price, popularity and newness. On the right-hand side, you’ll find a list of product categories. Now, here’s where the site lets itself down. When you click on any category with “free” in its title, you’ll get all of the site’s blocks—not just the free ones. While this is frustrating, all you’ve got to do is sort the page by lowest price to view all of the free blocks first.

While Allcadblocks (Boss888) isn’t the most sleek and accessible site available, you get exactly what you expect: free blocks. With a modest selection of 410 block collections, it’s certainly not too shabby!

13. First In Architecture

Screenshot of First in Architecture blocks

Our last choice on our free CAD blocks list is slightly different from the others. That is, it’s not a site dedicated entirely to blocks. First In Architecture is a go-to resource for anyone looking for tools, tutorials and tips for architecture. It doesn’t matter if you’re a hobbyist or a professional—they’ll have something that will help. If you’re looking for free CAD blocks downloads, they’ve got an entire page dedicated to new blocks.

The CAD Blocks page is laid out like a blog—you’ll find a list of separate posts dedicated to a new set of blocks. Some of the blocks released are provided by other sites like CADdetails, as First In Architecture is keen on promoting all types of blocks they think their users might be interested in. Additionally, they provide their own range of blocks—frequently updated to keep up with user interest. You can search for blocks in different categories including: accessibility, bathroom, construction elements and landscaping.

While the site isn’t dedicated entirely to free blocks, it’s still a great resource to bookmark. We especially appreciate that they tell users to get in touch if they’d like to make a request. It gives the site a more personal feel.
