dapayton Posted June 2, 2010 Share Posted June 2, 2010 Hey guys, real quick question. I have been given an autocad drawing of a pipeline layout, however the pipeline info is all given as flat. I am trying to go in and change the z values for the pipelines, however I am running into a problem.The pipeline sections have anywhere from 3-10 vertexes. I am trying to change each vertex's z value (elevation) to what the elevation is at that vertex point, however when I change one vertex it changes all of the vertexes in the entire section. How can I change just one individual vertex at a time? Autocad 2006 btw!!! Quote Link to comment Share on other sites More sharing options...
ScribbleJ Posted June 2, 2010 Share Posted June 2, 2010 My guess is that your pipeline is drawn with a polyline. PLines can only have one elevation per pline (ie each vertex z value will always change to the z value of the one you change). However the end points of lines can be drawn at elevation. Or you can draw a 3D polyline which will allow variable z values on per vertex. Quote Link to comment Share on other sites More sharing options...
dapayton Posted June 2, 2010 Author Share Posted June 2, 2010 is there anyway to change a polyline to a 3d polyline? Quote Link to comment Share on other sites More sharing options...
ScribbleJ Posted June 2, 2010 Share Posted June 2, 2010 I don't think vanilla AutoCad can but Land Development or Civil 3D can. Quote Link to comment Share on other sites More sharing options...
