Maximum envelope

[jan_ek]

Hello,

How to calculate the maximum envelope of several polylines given a list of points of each polyline.

Example on the screen

see this link

Not my idea.

Thank you very much, sorry for the unnecessary new post

Try this to avoid merging Polylines or modifying objects:

1. Create a selectionSet as  a vla-object
2. vla-get-boundingBox vla-object 'min 'max
3. vlax-safearray->list on each symbol to retrieve xy coordinate of limits

If you are wanting to calculate the area this is prob your best bet.  Objects have to be overlapping to work properly.
