IS there a way to find the problem with a non-closed polygon for a PCB outline?

[anthonyEX9NB]

My mechanical design colleague has created a PCB outline in Solidworks and then created a DXF version of the outline. I have imported this DXF file into my layout editor using the Design tab, then Place -> Insert DXF/DWG into an image layer (203bmp). There I needed to rotate the outline 180 degrees and then move the entire outline to put the origin in the right place. When I change the layer of this outline to the Dimension layer it is obvious that the PCB outline is not a closed polygon because the entire Dimansion layer is black instead of black inside the PCB outline and grey-sih outside the PCB outline.

Is there a way to find where the polygon is not closed?

Hello @anthonyEX9NB,

I hope you're doing well. The easiest way I've found to do this is to use the inspector and click each segment of the outline watching the inspector and making sure that the end of each segment is the beginning of the next. Eventually you find the correct segment. It's a pain but I don't know of a better way.

Let me know if there's anything else I can do for you.

Best Regards,

The other way is to push the outline to 3D PCB and then fix it in sketch environment. I usually draw a line to cut the sketch and locate the problem by looking at the profiles. For example, in the image below it's obvious the disconnected segments are on the top side of the sketch.
