Joining two cirlces doesnt wotk in Sketchup

[maar]

Hi,

I'm trying to join two circles and make "8" without two lines between circles. Am I doing it wrong or it is a bug?
I reproduced this problem, please take a look at my movie:https://youtu.be/r96e8dUUV1I.

Hi, welcome to Freecad and the forum,
Select both circles with your mouse, they change now color to green.
Select the tangent constrain icon.
The circles change like you wish

Hi,

Thanks for answer. Looks like I didn't make it clear what I would like to do. According to movie which I uploaded to youtube I made two circles with common area. I tried to delete this common area to have only one "object" but it doesn't work. There is unexpected behaviour, take a look at movie, please.

Br,
Marcin

I confirm the bug working " trim...picked position" with circles

A work around would be to use 2 arcs, with the rim points constrained coincident.

Hello Marcin,

Somehow your subject reads wrong (apart from the obvious typo in "wotk").

Joining two cirlces doesnt wotk in Sketchup

Sketchup is a totally different program...

In FreeCAD it is called the Sketcher.

The Sketcher Trim tool has never worked well with circles... Unfortunately no developer has managed to improve how it works with circles thus far.

Yes, you are right, it should be Sketcher. However, do you have any idea which file covers trimming implementation? I'm C/C++/Python developer so maybe I'll find a bug.

Have a look at the Handler which is responsible for running the correct python command and the trim function itself.

Any help on the code would be appreciated.
