Almost all who are working in the field of engineering design and are using AutoCAD as their primary CAD software would have felt the need to convert a 3D polyline to. PLINETYPE also controls the polyline type created with the following commands: BOUNDARY (when object type is set to Polyline), DONUT, PEDIT (when selecting a line or arc), POLYGON, and SKETCH (when SKPOLY is set to 1).

Riley Steele Squirt Class. Almost all who are working in the field of engineering design and are using AutoCAD as their primary CAD software would have felt the need to convert a 3D polyline to a 2D polyline. Robocopy Long File Name Support. In the field of Civil Engineering, survey drawings consists of hundreds, if not thousands, of 3D polylines. But a designer needs to convert them to 2D model to work and plan on that. It’s a pity that AutoCAD (already into Release 18) has still not addressed this problem, and given a ready-to-use command.

If they would have it would have been a boon for engineers. Most of us use some sort of customized scripts to acheive the job, and for those who do not do so already, here below is a LISP script which you can use to your free-will to do this haunting task.
