Working with angles and multiple parts

Post by BartvanS »

Hi Everybody,

I am new to freecad and I am trying to recreate this design: https://www.thingiverse.com/thing:2188329.

My version will be made to support a vesa mount(those used to hold a monitor). This is what i currently have:

https://ibb.co/Yp90fps

As seen at the thingiverse design, i still need to implement a xbox controller holder.
The problem is that that i cant just extrude something. The xbox holder needs to go sideways.
This is what i did so far:
https://ibb.co/6ZJL6qy
I tried to hack it by padding it to the desired position, the center and then pocket the remainder off. The pad function gives the error: "pad: result has multiple solids. this is not supported at this time."
Can someone show me the correct way to tackle this problem? my file is given as an attachment named "vesa".

Any help would be very much appreciated!

Hi and welcome to the forum!

When doing the pad check the "Reversed" box.

Besides: The thing is symmetric, so it would have been easier if you had made it symmetric to the Y axis.

Try checking the reversed checkbox.

Welcome to the forum, pretty good first post.

You managed to include all the useful info required, pics as well! :D

Alas I don't really understand the problem. To create a pad that doesn't throw the error, click 'reversed' button in pad dialogue(Padding is out of the screen as one looks at the sketch.)

You can then proceed with pockets. A note about your model, it is almost always best to centre everything around the origin, makes using the std planes much easier. ;) :)

"To last" would be stable, "To face" is prone to break due to the topological naming problem.

Hi Y'all :) !

Thank you for the very kind and quick response! Very helpfull. I am still not really clear on why the reversed option worked the way it did and although there probably is a better way to do this that I still need to find, is my first version done!
link!

Thank you all!

Looking at the sketch plane a pad get's out towards you which means in this case it is not on but rather besides its support. It then has no intersection with the rest of the body, which is (currently) not allowed. Reversing the pad makes it go away from you.

I have created lots of models, and I still need to check reversed at times when I did not expect it. I believe FreeCAD is 100% repeatable with respect to this function, but humans are not. :o

If you are working purely on the x-y plane then there are few suprises. However, for most other orientations it is not easy to figure out which way is up.

Just hit reverse when needed.
