Re: Topology optimization

Yes, but sometimes it is not so clear if you look at specific method. Frequent classification in structural optimization is to Size optimization - e.g. searching for width and high of cantilevered beam Shape optimization - searching for outer shape, e.g. by moving surface nodes Topology optimizatio...

Re: unable to make a pocket on a cylindrical surface

@chrisb I've got 2 other problems, about the same project: 1) There is a problem with Pocket 005 wich seems to not be connected, but, as there is a line and a arc of circle, and I already have 2 coincident constraints, I can't see why I have the message "wire not closed". More : 2)Before I tried to ...

Re: unable to make a pocket on a cylindrical surface

Great! Thank you @chrisb! I have some questions for you about the "check geometry" tool: 1)when do you use it? (always? just when your part have some bugs? else?) 2)Is this tool only available in the Part WB? 3) how did you see that the firtissue was introduced at pocket 4? I tried to run the check ...

Re: v0.18 Thread 6 - Regular Feature Requests

59 Part Design Matael allow PD sketches to be offset (as in Sketcher)
60 Part Design Matael allow new sketch at angle to existing sketch

@wandererfan

It seems that this is exactly what "datum plane" in PD WB make, so I think this 2 can be crossed out

My bad

Re: unable to make a pocket on a cylindrical surface

Hi! I think I wasn't clear enough. What make me unhappy is the result of the last pocket: 2018-02-23-103407_605x490_scrot.png which is quite ugly, and sometimes put the piece in black. And I would like to have something as clean as you here an other "bug" in the result: 2018-02-23-103642_964x659_scr...

Re: v0.18 Thread 6 - Regular Feature Requests

I think you can go directly in one multitransform from the first to the last image. You can get something with 16 times the firts pattern, but not with the same organization and it became to be a little bit tricky, and if you want to have more patterns, it became really hard, because you can only s...

Re: v0.18 Thread 6 - Regular Feature Requests

I would rather say "improve" instead of "increase" Haha, sorry ;-), my fault -allow transformation (multitransform, mirror) of shape from an other transformation (for example : make it possible to make a mirror of a multitransform, or a mirror of a mirror) I am not sure about this. It might be all ...
