エラーも無く、ただ真っ黒になってしまいます。
何故でしょうか?

元々、厚み > 内側に向かって厚みを作成
の段階で、フランジ部が厚み分の面が出来るのですが、これが原因でしょうか?

* TNP : no sketch upon face, expressions
* use axis and symmetry
* Thickness before top pad :!: :!: :!:

@Shalmeneser

Thank you for your response.

* Thickness before top pad
This was the cause of the problem.

* no sketch upon face
I am still a beginner. In the sample you attached, after Pad, does Sketch001 select the XY face and start sketching?
How is the reference External Geometry referenced in Sketch001?
Please let me know if you don't mind.

Because the Tickness is trying to cut the top pad, imho.

Sketch001 is upon XY-face.
But

Code: Select all

Pad001.dimension = Pad.Length + 20mm
or offset this sketch to

Code: Select all

Pad.Length 
.
