Remove duplicate vertices of a polyline

This command allows to delete duplicate vertices of a set of 2D or 3D polylines. This command is very important and should be used first to correct malformed polylines. Indeed, such polylines can cause errors on other commands and increase drawing size.

Command options :

• For 3D polylines, use also Z coordinate for comparison : 2 vertices will be considered identical only if their X, Y and Z are identical if this option is selected, otherwise they will be considered identical as long as their X and Y are identical.
• Preserve polyline Handle : if this option is selected, the polyline will preserve its identifier within the drawing. In the opposite case, a new polyline with a new handle will be created, and the former polyline deleted. It is usually counseled to preserve this handle, certain add-ons (like Activeline for example) using it. However, in the case of polylines having many vertices (several thousands), the operation can be largely slowed down. Therefore, if you have many polylines with many vertices to treat, and if the Handle is not important, use this option.

Remarks : None.
