Furion Posted March 5, 2012 Share Posted March 5, 2012 Hello. I have a polyline which consists of straight lines and curves in 2D enviroment. I want to extract some coordinates. I usually use block refferences and "dataextraction" command. However, the problem is as follows: I need to mark many things along the polyline's way at no constant intervals (not possible to "measure" it) If I have "osnap" on, I can't hit the spots I like for obvious reasons. If I have "osnap" off, I can't place the object accurately on polyline's way. So, what I need is: how to allign multiple blocks to a said polyline. Allignment needs to be done as accurate as possible, prefferably perpendicularly to closest tangent of polyline. If there are other solutions to this problem (as in topic) please do post them aswell. Thank you in advance for your time. cheers Jerzy B. Quote Link to comment Share on other sites More sharing options...

nestly Posted March 5, 2012 Share Posted March 5, 2012 Are you familiar with the NEARest Osnap? Automatic alignment could be done through an alignment parameter in the block, or by lisp (see below) http://www.lee-mac.com/objectalign.html Quote Link to comment Share on other sites More sharing options...
