Corner Snap angle tolerance

Arc minimum radius

Circle minimum radius

Arrow Line maximum arrowhead length

Dash Line dash length and gap length

Hatch Line angle tolerance

Most of the settings on the Advanced tab require a value in pixels. To determine a distance in pixels, display a grid and count the pixels or measure the pixel distance using Ctrl+D.

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

Corner Snap angle tolerance

Before Corner Snap	After

When a Corner Snap is set Scan2CAD deletes any chamfers joining two potentially intersecting lines and snaps the lines together to form a corner.

Before Corner Snap	After: angle too acute

If the angle between two potentially intersecting lines is too acute or too wide, it makes little sense to snap the lines together.

The Corner Snap angle tolerance constrains the angle between lines that are snapped together so that only lines that form angles close to 90 degrees are snapped.

A typical value is 6 degrees. If you select an angle tolerance of 6 degrees, Scan2CAD snaps together potentially intersecting lines that form an angle between 84 and 96 degrees.

Arc minimum radius

Scan2CAD only identifies arcs with radii larger than the minimum radius.

A typical value is 4 pixels.

Circle minimum radius

Scan2CAD only identifies circles with radii larger than the minimum radius.

A typical value is 4 pixels.

Arrow Line maximum arrowhead length

Scan2CAD only identifies arrows with heads shorter than the maximum arrowhead length.

A typical value is 64 pixels.

Dash Line dash length and gap length

Scan2CAD only identifies non continuous line types where:

The dashes are shorter than the maximum dash length.

The gaps are shorter than the maximum gap length.

A typical value is 45 pixels for both dashes and gaps.

Hatch Line angle tolerance

Scan2CAD identifies areas of lines as hatches if the angles of the lines in those areas fall within the angle tolerance of the selected hatch angles.

A typical value is 8 degrees.

For example, if you select Hatch 45/135 in the Object Identification tab and select an angle tolerance of 8, Scan2CAD will search for areas of lines with angles between 37 and 53 degrees and 127 and 143 degrees. Areas of lines at these angles will be identified as hatches.
