Replace dxf without losing references

[C_Spagnolli]

Hi,

i am using a dxf to make a project loop inside a sketch. I use the loop to be able to replace the dxf outside the sketch. But sometimes it works and sometimes it doesn't.

Check the video, if you want to try I put the files.

I believe that the problem in Projection operation in the sketch. Take a look at my file. The main idea is to using projection contour from the surface (not from imported curves). And in the trim feature need to select all curves using rule (all curves in the feature).

Great solution ...
The loop with the edge of the surface is stable.

I try to write to technical support to also improve the loop with the imported curves.

Thanks so much @YaroslavSin
