RLKHydro Posted November 9, 2000 Share Posted November 9, 2000 We are trying to find a way to join two open polygons. We frequently need to trace lines on bitmap images (for example, a particular elevation line from a topo map). Sometimes these lines are quite long (100+ vertices), and are difficult to draw in a single pass. But if you stop one polygon and start another one at its endpoint, is there a way to join them together? The "join" command does nothing in this instance (unless we are using it incorrectly). "Add surface" works, but turns the resulting shape into a closed polyline, so the "perimeter" value in the object info pane is no longer accurate. Any suggestions? TIA-- Barb Nelson RLK Hydro, Inc.

PeterT Posted November 9, 2000 Share Posted November 9, 2000 Why not just group the two polygons, then they will be one object, and the Info Palette will correctly display the total perimeter length. ...or is there some reason you need the final object to be of the type "polygon"? Hope this helps, Peter Thayer Quote Link to comment
RLKHydro Posted November 14, 2000 Author Share Posted November 14, 2000 Thank you, Peter. That does solve the problem for figuring the total perimeter. While playing with it, we discovered that if you even just "shift-click" on each one, the perimeter will increment correctly. Don't know how we missed that! But still it would be nice in some cases to be able to join them into one polygon--when there are many to be joined, for example. Also, the grouped polygons don't always fill as you'd expect, although that's not a problem in this particular drawing. Sorry for the delay in replying, I ended up being out of the office for a few days. Barb Nelson RLK Hydro Quote Link to comment
