Trouble trying to Pad

Post by Devron »

Hello I am trying to pad a grid design sort of like a cookie cutter square shape, buy I am getting the error, Creating a face from sketch failed.
I have attached the file, if anyone can help please ? I think it might be because some of the lines are not linked to the edges but not sure on how to do that if thats the problem. I have Validated the sketch and no problems were detected.

Sketches used for padding must not have tee-junctions.

After removing the improper line segments the sketch is no longer fully constrained, but I did not fix that.

Aside from that which Gene pointed out, this would be better done using a feature pattern.

Yes, it was late and I did not take enough time. Drawing individual boxes is quite inefficient in both time and computation. The use of arrays of some sort is highly recommended.

As a beginner, however, it is probably one step at a time. ;)

If you want to fit an array into a shape that might change then with what FreeCAD offers doing this via a sketch is probably easier.

Depends on the number of boxes, and especially if this number is subject to changes.

Unfortunately the sketch array is not that usable otherwise I would agree
Btw the sketch Array uses itself a hack with distance guides

As I stated current FreeCAD array tools already lack the ability to put an array into a boundary.
Adjusting the design is an additional step after creation.
