I would like to give a part a wall thickness of 1 millimeter with just one operation.
In my opinion, this should be possible with the extension Fredo Joint Push Pull.
It works, but not quite as it should. Possibly this extension is not suitable for this, or I am not doing it right.
I would like your advice. Thanks in advance for your suggestions.

If you are working with very small /thin components then you may well have better success if you scale your model larger for modelling - then reduce it at the end.
As a tool designed for Architecture, SketchUp is internally wired to deal with bigger objects - and its math does better with larger numbers.
Thx for your response.
Sorry for my lack of clarity. I am talking about 1 millimetre, but I have already ‘inflated’ my drawing to metres precisely to avoid this. 1 millimetre is 1 metre in my design.
All points must be coplanar
Probably too late to the party but I decided to give that thing a go from scratch just for fun. I would recommend modeling it centered on the origin so you can use the origin and the axes for reference. I would get the thing 3D with the through holes and openings before detailing the inner wall and other bits. Here I made the recessed area around the central hole before I remembered to take the scree shot.
After that the other features can be added to both the top and bottom.
Why do you you do that, you can model using real measurements, if you need to make 2D images out of the 3D model you can export it to layout and scale it there.
That’s done a lot with small objects to avoid the tiny face issue. It’s called “The Dave Method” after @DaveR. You can probably find lots on it here in the forums.
The cause of why things are not going according to plan is clear to me with this. Thanks for your explanation!
Why the points are not coplanar I unfortunately do not understand.
In fact, I created 1 corner and brought everything neatly from the center via ‘Flip’ to the remaining three corners.
I will draw it again and see if it goes right then.
Well, the speed with which you were able to draw this I don’t imitate you Thank you too for your input.
When drawing, did you use an extension (Fredo Joint Push Pull for example) for creating the wall thickness or just the SU native tools?
No. I just outlined the wall thickness before raising it. The only extension I used in modeling the whole thing was Solid Inspector 2 because I knew after adding the triangular gussets they way I did I would have internal faces to remove to leave a solid component and I knew that Solid Inspector would remove them for me. I was getting lazy at that point but I could have modeled the gussets without creating the internal faces if I’d wanted to.
@DaveR That gives a lot of clarity. Thx Dave. I will practice again and look to design it with the native tools.
@francisquitof What @RTCool describes is exactly the reason. Almost all the parts I design are relatively small in size. I use the designs for my 3D printer.
This method works just fine!
FWIW you can see in my first screen shot that I already outlined the wall thickness. Once that was extruded up to the height of the corner blocks (they probably have an official name but I don’t know) and then I outlined the thickness of the walls over the corner blocks and pull the face up again.
I had to rack my brain quite a bit. This is a design that I thought was fairly easy to draw, yet requires more engineering. I was fairly wrong about that
But in the end, I was able to create a solid model using only native SU tools. Here is a print screen of the final result
Oops… and now without the upstanding edge
Good. There are a few dimensions missing from the drawing so you have to figure them out on your own.
