create sketch and fc refuses to pad it

Post by dr who »

Hi,

I created a sketch, that becomes invisible on pad action.
I tried the pad checker, but when I let the checker remove duplicate vertices, the sketch turns into error state with redundant constraints.
Deleting all redundant constraints turns the sketch into white colored lines, which means that the sketch is not fully constraint.

Need some help. How can I get rid of the real problem and remove it?

Your sketch is un-maintainably complicated. Separate the pad and pocket, use the mirror symmetry, use equality constraints rather than equal dimensions. Construct the basic shape with the multiline tool with straight lines, add the filets with the sketcher fillet tool.

@edwilliams16 is right : un-maintainably complicated.
What is the logic ?

Some dimensions are important :
* circles radius/position
* global form

Some dimensions/constructions are for aesthetic purpose only.

Try not to mix everything !

Hi @edwilliams16,

thank you very much for your help!
Separate the pad and pocket, use the mirror symmetry, ...
Yes, I wanted to use mirror symmetry. I created half the sketch and tried to use mirror from sketcher - but it reported the sketch as invalid. Didn't know, that I have to close half the sketch before mirroring.

The complicated creation is due to the fact that I had the blue construction elements as input conditions. As well as the fact that it is to be made from an 160mm round.

I try to do it again according your advices. Thanks!
