Re: Sweep - Deformation of profile

Maybe your contractor ask you for constant radii at each bend I do a helicoïdal path and select each vertex one after one (it's long and boring because if we select a worth one , we have to redo all from the begening) but the file is very load : 20.6Mo The time calculation is very short 1or 2 sec C...

Re: Sweep - Deformation of profile

Dear all, It turns out that the deformation of the sweeped profile relates to the corner transition and orientation mode settings. Replacing 'frenet' mode with 'standard', and'trandformed instead of 'Right corner' as corner transition improved dramatically the outcome. However, for some reason, the ...

Use Partdesign it's better way to do it
the file is to large : 6.2Mo
I do not follow your suggestion, but would be grateful for clarification of a more suitable way for generating the center line of the coil?

Re: Sweep - Deformation of profile

Dear all. Following the successful design of a conical coil as previously discussed, manufacturers of numeric bending machines faces difficulties in achieving a successful import and processing. Instead, they now suggest a modification of the coil shape design from circular to squared as indicated i...

Re: WB Sheet metal - perforation and unfolding

changing the bending radius resolved the error when unfolding. Thank you for your support with this issue. Only the issue related to cut out of the symbols remains. Symbols are contained in a sketch which is fully contained/defined. When applying the pocket function in WB Part design, an error messa...

WB Sheet metal - perforation and unfolding

<t>Dear fellow Freecad users, <br/> We are preparing an item using the sheet metal WB, see attached. Some of the bends have cut outs and one of the perforations (two symbols made in a sketch attached to the sheet) fail to cut through the sheet. Unfortunately we do not understand the root cause for t...

Re: Sweep - Deformation of profile

Dear all, Thank you for your support and valuable input for resolving this issue of designing a coil consisting of straight parts combined with bends with constant radius. The item is a heat exchanger and the bending machines are are capable of producing items with straight parts or bends with const...

Sweep - Deformation of profile

Dear Fellow FreeCAD users, We are preparing the design of a tube coil applying the sweep feature of FreeCAD but face a challenge, maintaining the profile shape when sweeping along the center line of the part, and we would be so grateful for your contribution for overcoming this problem. 1. Original ...
