https://forums.autodesk.com/t5/vba-forum/lengthen-in-vba-without-using-sendcommand/m-p/1622493#M35018 I have several polylines which consist of many lines and arcs joined together. I need to trim these polylines to specific lengths and then offset them. In AutoCAD, I use the LENGTHEN command, with the Total option and then the OFFSET command. <BR /> <BR /> In my VBA routine to automate this process, I tried using SendCommand to do the same, but the polyline length is not updated until my VBA has finished running. If I check the length of the polyline after executing the LENGTHEN command, it is still the original length, but once I end my program, it is updated to be the total length I specified. Because the length is not updated, my offset polylines are the original length, not the new total length specified. <BR /> <BR /> I have tried updating the object, regenerating the drawing, everything I can think of to update the polyline after executing the SendCommand. <BR /> <BR /> Any ideas or alternate VBA methods (without using SendCommand) to accomplish the same procedure would be greatly appreciated. <BR /> <BR /> TIA, <BR /> Matt Mon, 24 Apr 2006 16:43:38 GMT Anonymous 2006-04-24T16:43:38Z https://forums.autodesk.com/t5/vba-forum/lengthen-in-vba-without-using-sendcommand/m-p/1622493#M35018 I have several polylines which consist of many lines and arcs joined together.

If you need the updating to be <BR /> syncronous. You'll have to reproduce what the lengthen command is doing <BR /> using vba.<BR /> <BR /> -- <BR /> ----<BR /> Ed<BR /> ---- Mon, 24 Apr 2006 16:49:46 GMT https://forums.autodesk.com/t5/vba-forum/lengthen-in-vba-without-using-sendcommand/m-p/1622494#M35019 Anonymous 2006-04-24T16:49:46Z https://forums.autodesk.com/t5/vba-forum/lengthen-in-vba-without-using-sendcommand/m-p/1622495#M35020 I don't think the Lengthen command itself is available in VBA, unless I missed it. How would I reproduce it using other commands?
