rbkla Posted September 29, 2014 Share Posted September 29, 2014 I have imported a survey from AutoCAD and the contour lines are made up of thousands of connected line segments. I am trying to change their appearance from solid to dashed. I've edited the line appearance in the class but the contours show up as only partially dashed, which leads me to think that there are overlapping line segments . I'd like to convert all lines on each contour to a single polyline-can I do this? Thanks, Rose Quote Link to comment
Vectorworks, Inc Employee PVA - Admin Posted September 29, 2014 Vectorworks, Inc Employee Share Posted September 29, 2014 If they are connected end to end, normally yes. Select one of the line segments, then Edit > Select Connected Objects, if it then selects a number of other line segments, these can usually be combined into a single polyline via Modify > Compose.

rbkla Posted September 29, 2014 Author Share Posted September 29, 2014 Thanks for your quick reply! I was able to connect the ling segments and then when I used the command Modify>Compose it joined them all into a polygon. I tried to then use Modify>Convert to change to a polyline but it doesn't look like this is an option. So I then deleted the fill from the polygon and changed the line type so it looks like I want it to (single, dashed, joined line) but am I going to get into trouble down the road having all the contour lines as polygons instead of polylines? Is there a way to now change the polygon to a polyline? Thanks, Rose Quote Link to comment
Vectorworks, Inc Employee PVA - Admin Posted September 29, 2014 Vectorworks, Inc Employee Share Posted September 29, 2014 Well a Polygon would just be a polyline that was closed and had a surface to it. If you use the split tool to break it into edges that do not close it would be a polyline. For many purposes though, a polyline and polygon are interchangeable. Quote Link to comment
rbkla Posted September 29, 2014 Author Share Posted September 29, 2014 Thanks again, Jim. I did try the split tool but it just breaks the polygon up into smaller polygons. Is there an additional step for splitting from polygon to polyline? I can probably just keep the contours as polygons-just trying to understand the process a little better. Quote Link to comment
Vectorworks, Inc Employee PVA - Admin Posted September 29, 2014 Vectorworks, Inc Employee Share Posted September 29, 2014 You should be able to use the polygon without any conversion in the creation of the site model, are you not able to convert them to 3D contours? Quote Link to comment
rbkla Posted October 1, 2014 Author Share Posted October 1, 2014 At this point I am just using 2D so the graphics are the only considerations. Looks like there is no problem w/ having polygons-just not sure if it takes up more memory. Thanks again for your help. Rose Quote Link to comment
