How to place a pad?
Hello,
I couldn't figure out how do I place a pad at a specific place.
Regarding the attached screenshot, I wanted to move the highlight pad in the x axis. I've also tried to create a new body to sketch this pad in, but couldn't create an edge link in the sketch, to the exiting body sketches.
I've also attached the FreeCAD project.
Thanks

Re: How to place a pad?
Actually you have to move the sketch accordingly, not the pad. A good way is to select the sketch in the treeview then modify its placement property.
IIRC the Z axis is always normal to sketch.

Re: How to place a pad?
The image suggests that you should not move the sketch directly, but rather change its attachment.
This might be a bit tricky:
It is intriguing to attach the sketch to the appropriate face.
However this is not recommended, because you loose stability in terms of topological naming issues.
A proper way would be to attach a DatumPlane to Sketch, and then place Sketch003 on that DatumPlane.

Re: How to place a pad?
Thanks openBrain and chrisb,
I've tried that, Placement -> Position -> x can't be changed (see screenshot)
I didn't found how to set the DatumPlane x offset (see screenshot)

Re: How to place a pad?
If there is ATTACHMENT the PLACEMENT is derived from that. So you need to change attachments offsets (position x,y,z, axs, angle).
Re: How to place a pad?
- Select the Sketch
- Switch to the Data tab
- Select the "Map Mode" or "FlatFace" field
- Press the [...] button that appears
- Set the Attachment Offset values
Re: How to place a pad?
Thanks kisolre and NormandC!
That worked, because I changed the Z axis value, in contrast to the previous attempt, which I changed the X axis . I understand now that the attachment offset axis are relative to the sketch and not absolute, that’s a bit confusing.

Re: How to place a pad?
Yes, I assumed a single axis system, Its clear now. Thanks.
Re: How to place a pad?
I had another look at this model, and have some comments:
- Your Sketch contains redundancies: symmetry implies here the horizontal constraints. Usually you should remove the latter.
- I attached a DatumPlane to the sketch at the appropriate edge, this makes the offset obsolete
- I had to move the sketch to be aligned with the box again - and now you have to delete the symmetry anyway.
- I reversed the Pad in the attached example, that may be wrong.
