Trim leaves a tail

QCAD Professional QCAD Troubleshooting and Problems

Hello,
Edit: OS: Win10, QCAD: 3.24.2
I’m having a strange problem where trimming a line leaves a tail beyond the limiting entity. In the attached picture, the blue lines were created using “parallel with distance” from the thick black lines. When I try to trim the ~horiz line to the ~vert it leaves a little overshot tail.

If I draw new lines manually they trim fine. Also, if I split the horizontal entity into multiple segments, it also trims fine.

any advice would be much appreciated

Please attach your drawing file (DXF, DWG). Reduce to demonstrate problem if necessary.

Hi,
Thank you for your replies! I attached a reduced file.
Try to trim one of the horizontal blue lines using a vertical blue line as limiting entity.
I’m new to QCAD so please forgive if I made some silly mistake.
Thanks

CVH was spot on: there are several 3D elements with Z coordinates. You can use Misc > Modify > Flatten Drawing to 2D. Obviously this will get rid of the Z coordinates.

thank you CVH & Andrew. How do I identify the 3D elements? The source of this file is an older format DXF, and I suspect it’s created as part if the import.

Z isnot zero.
