Such tools are on my wishlist. I told this many times here in the forum, but we need someone to program it.

Hi Maurice,
I explored some defeaturing-wb.
Great to have a edge copy tool. But it's not parametric. Please check if it's possible to create it parametric.
What about edge offset. Please can you explain how to use.
Thank you so much for your creat work.
Best regards
Wilfried

I know, but things can be implemented in different ways. Some ways can be quite easy for developers to do but also quite useless for the different users, some ways can require more work from the developers but can also be quite useless for the different users and as you probably know from my arguments on other tools I strongly dislike this and I am always searching and trying to find good and proper ways to do things. Werner can probably implement some of this ideas with closed eyes, but it can be very helpful for him and other developers if we can have a good and quite exact specification on how it should be done and agree on it.

I am very open in how such tools can be useable. That means that I'm not saying this tool should look and feel like a Creo tool. Freecad sometimes is very different, but I like it very much.

Hi Wilfried
freecad-heini-1 wrote: Sun Jul 08, 2018 7:23 am By the way a edge chain / set selecting tool is also missing. The path-workbench has such a tool, but it's not working in other workbenches, I don't know why:

1. I have added the nice Path Loop Edge to my WB (thanks to @sliptonic for this nice tool)

2. Edge and Face can be copied and translated by an offset. The offset can be assigned in the middle text box. Over it to get the tooltip

I upgraded the defeaturing workbench tried this tool, but it does not work. If I change into the path workbench, it work without problem.

I copied faces, changed a sketch from an extrusion, but the copied faces are not parametric. Same with edges.

Anyhow, thank you so much for your great work.

Offset is not parametric ATM, I will have a look at later on.

Hi Maurice,
after upgrade the workbench everything is fine with the Loop Edge tool.
Concerning edges or surface copy, Lattice2 sublink can do the job, full parametric.
And in the part workbench 2d or 3d offset tool is full parametric.
Best regards

https://peertube.mastodon.host/videos/w ... d8e6783872

I tried to use PeerTube, not bad for the first test.
The video is in German language.
The face selection panel is fixed now, i.e. the label no longer "explodes" when too many items are selected.
And there is now a stand-alone command for box selection of faces (see Part menu). This is a WIP and the long-term goal is marry its functionalities with the box selection of the core system (see Edit menu).
