|french curve : FREE Source Code!
This code allows the user to continue any arc tagentially from either end. Basically it's like a french curve for AutoCAD.
AutoCAD allows you to continue the Last ARC drawn, but there is no easy way to continue any ARC tangentially from either end.
When you select an arc the FCURVE command sets the current layer to the selected arc's layer and continues tangentially from whichever end the selected point was closest to.
The lisp is fully commented and I have also attached a DWG file and DWF file with some curvilinear shapes created using this routine.
