Re: FreeCAD refuses to create fillet
Nice looking piston. I think this fillet is simply too hard for FreeCAD. The issue is that the edge ends at a curved surface at an angle. The fillet algorithm does not know how to make the fillet fade out at the end of the edge. I think you have to do this manually. Maybe you can try drawing the fil...

Re: [Sketcher] Distance to circle
So you can create a distance constraint and put two circles as the parameters. It's just that the solver won't solve it. Is that right? In which case question is : in which solver do we need to add support to this new kind of constraint ? Because if I'm not mistaken there're several solvers no? Nop...

Re: [Sketcher] Distance to circle
Yes it's very similar. How far did you went? Do you have a githug branch? I have created the new constraint. It is not working yet. I have not yet looked at how to make the dimension handles be drawn in the sketch. I have a branch in my local git repo. I will create a [WIP] PR so you can see. If yo...

Re: Integrating a user poll system
- How often they us a CAD? - How often they use FreeCAD? - How generally skilled they are CAD (trained monkey vs. no trained monkey, technical interests and/or background? - How will you count them - Security I don't think anybody is suggesting that these polls will be be final decision on the matt...

Re: Frequency analysis for cylindrical shell
I like old books. The deformations are small compared to shell-thickness 1) This is not the case for a normal shell, and especially not for ANSYS SHELL181 that even supports large rotations. Anyway for a linear modal analysis the displacements are small by definition. So thickness does not matter. ...

Re: Integrating a user poll system
I don't see the harm in trying this. After 6 month we make can make a poll to ask if the poll function should be removed. The feature should be configurable so it can be turned off. And it should link to the forum poll so that no user data is sent. My concern is not bad votes, but rather spam and ma...

Re: [Sketcher] Distance to circle
I think they are not implemented because it is a bit complex to implement and nobody has done it. Also because you can achieve the effect with the help of construction geometry. I am currently working on something like this right now actually.I was originally thinking of this use case https://forum....

Re: Frequency analysis for cylindrical shell
2. and the deformation of the shell is small against the thickness Have a look at the deformation/thickness ratios. For 1 mm shell it is > 1, so the theory is not valid. Sorry but the magnitude of deformation in a mode shape from a modal analysis is not physically meaningful. Even if this was not t...
