#Autocad lisp intersecting polyines software
With this, you end up working a lot with polylines, thus this post is sort of a collection of polyline tools both native to the software and then some additional 3rd party tools / code that can assist in generating and cleaning up polyline boundaries.Įxtracting Polyline Boundaries from Surfacesįor generating boundaries on corridor surfaces, I feel these two commands get overlooked - but are very fast and helpful. Often in this work I find myself having to create boundaries for my various surfaces to 'clip' the surface so that it is ready for pasting.

My workflow in grading has been to utilize all types of Civil 3D grading tools (feature lines, grading groups, corridors, etc) and ultimately paste surfaces together to create a final surface. The Break Crossing Objects action corrects apparent problems across layers and may break lines meant to indicate separate objects, such as rivers and roads. I tend to do a lot of work with grading and Civil 3D Surface. Note: AutoCAD Map 3D does not refer to a tolerance value when breaking crossing objects. It means you have vertex points along your polyline that overlap each other. This time however, you can select all of your objects at once and the combined outline of all of the shapes will be turned into. One of the most common is Polylines to Lines. Converting a PolyLine to a Line When working in AutoCAD it is often needed to convert linetypes. I know that last week I said I'd be posting these weekly now and given that I'm a day late on this post, hopefully it's still helpful to you. Here is another polyline routine that only works with closed objects (closed polylines, circles, ellipses). Find out more about this and more by attending our Basic Essentials AutoCad training course. When I was a kid I recall my dad using the phrase 'a day late and a dollar short' off and on.
