Modify | Trim | Offset Curve

This tool is similar to the Parallel Line tool but allows the offsetting of arcs and circles as well as lines.

A fixed offset value can be input, which remains fixed until changed by the user.

This tool is discussed and demonstrated in more detail here.

Repair Curves

Modify toolbar

This tool provides an integrity check of all gaps and duplicates in a collection of curves. In the example below, points 1 and 2 contain duplicates of the same object which are concealed in most views.

Modeling features such as extrusions and lathes cannot be performed when duplicates and gaps appear in the profile and such errors cannot be easily found when there are multiple curves.

Repair Curves – Duplicates

Duplicate objects hidden beneath line and circle

In the example below, the entire collection of curves was selected for repair.

Duplicates found and identified in selection

Repair Curves – Gaps

In the example below, the line does not connect to the circle by a distance of .250, therefore when the tolerance is set to anything above .250, it shows a gap to repair.
