Can't pad mirrored sketch
Hello,
I grabbed an STL (ugh way to start) and converted to a part. I created a sketch, put it where I wanted and padded it. Perfect.
Then, I mirrored the sketch. I moved the sketch to the correct body, changed the attachment where I wanted it.
Then, I hit "pad" and not only does it disappear but so does the previous one.
If I pad it while it's touching the original it will pad. But then I can't move it outside of that physical constraints.
Can anyone school me? I can't attach the file because it's too large.

Re: Can't pad mirrored sketch
Don't mirror in the sketch.
Only sketch half. (I'm assuming you are using a Body and have dropped the converted solid in, thus creating a BaseFeature) Then Pad it. Then Mirror the feature created by the Pad.

Re: Can't pad mirrored sketch
Hmm. Okay, I did not mirror "in the sketch" per se. I mirrored the actual sketch. I made the "U", padded it, the mirrored the sketch.
You are saying do not do that. (And yes, I am using a basefeature).
So, then you are saying to mirror the padded objected after? That seems to just stick it on top of itself and I cannot move it.
Thanks!
Re: Can't pad mirrored sketch
It is being mirrored around the sketch axis? This the default.
Is the sketch at the center of the imported component?
If so, then the U shape should be placed appropriately to end up where you show it and the mirror a is will be correct.
Otherwise you need to create, for example a datum plane to mirror around.

Re: Can't pad mirrored sketch
Sadly, you're speaking above me. I've been using FreeCAD for a few months, and I've been reasonably competent,. Then I run into something like this and I simply don't understand what you are trying tell me.drmacro wrote: ↑Fri Jun 18, 2021 11:50 pm It is being mirrored around the sketch axis? This the default.

"it"? that pad or the original sketch? Either way, I don't know. But the sketch is at the origin, so okay. I can see that it would be doing that.It is being mirrored around the sketch axis? This the default.
No, it doesn't look like it to me.Is the sketch at the center of the imported component?
So, I need to figure out where, in the sketch plane, to place this sketch and then mirror it? Okay, I think that makes some sense.If so, then the U shape should be placed appropriately to end up where you show it and the mirror a is will be correct.
I'll try it out.
Re: Can't pad mirrored sketch
you could move the basefeature to the center, then the mirror default would work.

Re: Can't pad mirrored sketch
For such a symmetric thing you should move it before working on the model to be appropriately centered relative to the global coordinate system. It makes life much easier.

Re: Can't pad mirrored sketch
Think we should make a wiki page covering handling stl (etc.) in more detail and include instructions for @edwilliams moving macro...hmm

Re: Can't pad mirrored sketch
Such a page should start with something like (tongue in cheek): "The best thing you can do with STL files: avoid them as input format".

Re: Can't pad mirrored sketch
It would be great if everyone who produced something gave the source design as well.. but sometimes we're stuck with these stupid things :/
Thanks for all the help, everyone. I am going to start fresh and try to get the imported object centered and see if that helps my mission.
