I'm new to freecad, so far I made it this way :
Sketch a rectangle for the top surface, pad it, add filets for the corners. Then select to bottom face, make a new sketch, another rectangle, then a datum plane 40mm below, sketch another smaller rectangle, and make a loft between the two to create the bottom of the tray.
Now for the hole I made a rectangle on the top face and made a pocket with an angle.
Downside of this, the thickness of the walls is not equal. Ideally I'd like a 1.5mm thickness everywhere. And I'm not really sure how to proceed to make the separators inside the tray.
What is the most efficient way to do it? thanks
Note that attaching subsequent operations to generated geometry like this (faces made by pads, etc.) will make the model extremely fragile and making basically any change upstream from that will break it every time.
This may or may not improve with the upcoming 1.0 release where the topological naming bug is "fixed," but I'm not counting on it until I see it for myself.
FYI for anyone else stumbling on this in the future, you cannot at present pad-to-face in more than one direction at a time, i.e. the "symmetrical" option you can use with a normal pad is not present. Also, you can't pad-to-face onto any surface that is not geometrically flat; curved surfaces or even intersecting with two faces with an angle in between them will not work.
Thanks for these tips and provisos - they are true and important. ... How would you do the divider?
In this case as a loft. Not say that's necessarily the right way to do it, but that's how I'd do it. See my other comment on the matter here.
