Obviously there are conflicts to be solved.
I will do that later.

F5 is already present. It recomputes every thing that is marked to recompute. I added the Ctrl-F5 that marks to recompute and launch recompute. What can be done in 2 steps before can be done in one step. That is it. Shall I remove the Ctrl-F5? But that was not the purpose. This example was only here...

As soon as you will incorporate your part in a composed part (compound, fusion, cut, etc) but also make a pocket, ... you will fall in a trap with colors that cannot be solved without changing things in the architecture of the software: First to handle the colors the same way when creating the part,...

The concept of FreeCAD is very good, there is no point about that. See simply the OpenSCAD script. It is very simple somehow, fusions, cuts and intersections of a certain number of primitives: - Torus - cubes - spheres - cylinders FreeCAD should be able to do that in an even simpler way, but is not ...

Here is the OpenSCAD script. Capture700.JPG I made duplicates, the manifold is not valid. It is not practical, the software is slow.There is still some job to be done. But it is almost there in a couple of hours. There are many tangent faces etc. eps=0.01; length = 50.5; ray1 = 5.0; ray2= 0.5; rayou...

Hello, I I have chosen FreeCAD at some point in time, it is because it is a paremetric cad and provide many functions and a quite efficient interface. I know exactly what a cad is, and what Blender is not. But nevertheless Blender can make part of the job, and I can control quite precisely what I am...

Hello, Sorry I missed that topic and the private messages that were sent to me since mid of October. The problem of transparency and colors is quite complex, and I think it need a restructuring of the architecture. The problem is not only to keep the colors of the basic object (imported or not) but ...

Ok I understand. Thanks for taking the time. For the moment the body cannot be removed to the cut part that is the overall shape this pipe should be removed, it ends with an error, again a tangent face probably. Still not to the end. And I still have now to model the external part to be removed, you...

I do not understand. At this level I would expect AdditivePipe to contain the 3 first segments and AdditivePipe001 to contain the last one. But why when I display AdditivePipe001 the display shows the tube along the full path as it includes only edge4: the straight part of the path as shown in edit ...

All sketches are in one body and the pipes also. Is that what you mean? Did you see the last example I gave you? To summarize I have not been able to make the model I wanted with FreeCAD. This step copying does not show up. But nevertheless should not induce errors. For cleaning you have an example ...
