Part Design Thickness - Non Implemented features

Post by bf5man »

I was playing with the Part Thickness and noticed the Pipe and Recto Verso Modes values don't seem to do anything. The Intersection checkbox also appear do be "useless".

Further investigating in the forum, I found this older thread from 2013: https://forum.freecadweb.org/viewtopic.php?t=4589:

Only Skin functions, Pipe and RectoVerso are not implemented yet.
[...]
Intersection specifies how the algorithm must work in order to limit the parallels to two adjacent shapes:
False: (default value), the intersection is calculated with the parallels to the two adjacent shapes;
True: is not completely implemented and therefore is not recommended for use.
Is it still the case that these features are not implemented ?

If so, my advice would be to remove them from the interface to limit the user confusion.

If we do so, then the Mode could default to shell and the Intersection checkbox could default to false and not be exposed anymore.

Thanks,

I'd like to know this as well. I struggled with these phantom features just recently.

I second this.

I'm not aware that anything has been done in that area. As thickness is one of the most picky functions and is heavily affected by topological naming, I have some difficulties to recommend to use it at all.

In case anyone cares: These Modes are still useless in version 0.20 :roll:

Thanks!
I still have no clue how to use Github, but I'm slowly working on that.

In general this tool does not work. I don't know if devs will ever fix this tool, for 3 hours i am trying to make a shell from a part, still didn't accomplished anything.
Specially to create inwards thickness. I don't know what to do, little free time i get to work on my project i waste in figuring out how to modify my design so freeCAD can work. In short i am modifying my design to fit freeCAD's need,

@rahmanshaber : can you provide your file ?
Thickness tool is a very sensitive tool and you can be happy if it works. :mrgreen:

That is indeed currently in quite some cases the only solution. You have to subtract the stuff that Thickness should remove by yourself with appropriate subtractive features or by modeling the inner part separately and then making a boolean cut.

@Shalmeneser So you guys know about that and i beleive it's one of the most important tool in the part design and devs are avoiding it?

@chrisb I tried different ways, but it doesn't work. If i do the thickness at that low level then what's the point of the freeCAD tools? also the part is too complex to do it manually.

I strongly believe devs needs to fix this tool ASAP, please.
