Here is a helpful tip that will let you make Polylines look like splines. Splines are great, but sometimes they are a little hard to adjust.
- Make a Polyline
- Double-click the Polyline to enter its (PEDIT) function. Or use the command PEDIT <enter> and select the polyline.
- Choose “FIT” from the list or simply type in F <enter> to make the selected Polyline into a “Fit Curve”
(Warning: Some AutoLISP functions won’t work with these types of modified Polylines so use as needed)
