If you have Sketch selected in the Type Menu, Scan2CAD ignores the settings in the Object Identification Tab.

Arc or Bezier

If you select Arc, Scan2CAD identifies arcs on the raster image.

If you select Bezier, Scan2CAD identifies Bezier curves on the raster image.

You cannot select both Arc and Bezier.

If the image is a typical architectural, mechanical or electrical drawing containing mainly straight lines, select arc.

If the image is mainly curvy, like a contour map, ship hull, aerofoil or freeform artwork you will get better results if you select Bezier. If you are vectorizing a curvy image with a view to cutting it on a CNC machine and the machine does not support splines you can still select Bezier. You can convert the Bezier curves to arcs or polylines on export.

If Scan2CAD fails to identify arcs or identifies spurious arcs you may need to modify the minimum arc radius in the Advanced tab.

Circle

If you select Circle, Scan2CAD identifies circles on the raster image.

If Scan2CAD fails to identify circles or identifies spurious circles you may need to modify the minimum circle radius in the Advanced tab.

Arrow Line

If you select Arrow Line, Scan2CAD identifies arrows on the raster image and vectorizes them to arrow lines.

Arrow lines are a line type that comprise three vectors making up the arrow head and one vector making up the arrow tail. The arrow head and tail are grouped together and exported as a block.

If Scan2CAD fails to identify arrow lines or identifies spurious ones, you may need to modify the maximum arrowhead length in the Advanced tab.

Dash Line

Dash Line selected	Dash Line not selected

In the diagrams above vector end points are enclosed in small squares.

If you select Dash Line, Scan2CAD identifies lines with non continuous line types like dash, dash dot, center, phantom and hidden. It vectorizes them to lines with a dash or dash dot line type.

If you don’t select Dash Line each dash or dot making up a line with a non continuous line type is identified as a separate line.

If Scan2CAD fails to identify dashed or dotted lines or finds too many dashed or dotted lines you may need to modify the maximum dash and gap lengths in the Advanced tab.

Polyline

If you select Polyline, Scan2CAD joins individual lines and arcs together to form polylines.

If you are going to edit vectors in Scan2CAD it is best not to select Polyline as many of the vector editing functions do not work on polylines.

If you don’t select Polyline you can create polylines after vectorization by clicking on Vector Edit Menu > Modify > Make Polylines. If you select Polyline you can later split the polylines into individual lines and arcs by clicking on Vector Edit Menu > Modify > Un-Make Polylines.

Arcs will only be included in polylines if Vector Edit Menu > Modify > Polyline Options > Include Arcs is checked.

Hatch

If you select Hatch 90/180, Scan2CAD identifies areas of lines at 90 and/or 180 degrees and groups the lines together as a block.

If you select Hatch 30/150, Scan2CAD identifies areas of lines at 30 and/or 150 degrees and groups the lines together as a block.

If you select Hatch 45/135, Scan2CAD identifies areas of lines at 45 and/or 135 degrees and groups the lines together as a block.

If you select Hatch 60/120, Scan2CAD identifies areas of lines at 60 and/or 120 degrees and groups the lines together as a block.

If Scan2CAD fails to identify hatches or identifies spurious hatches you may need to modify the Hatch Line angle tolerance in the Advanced tab.
