Sketcher -- How to sketch a Lozenge shape (or rounded rectangle)
I want to make this:
I tried to create a constrianed rectangle then put fillets on the corners but every time i try to make the ends round, i get an error. even if i kind of get close to having a lozenge shape and try to draw 3mm circles at the origin of the fillets or end circle radius, it won't let me. this ended up more of a challenge than I saw coming.
so then i tried creating circles at the ends, nope
I don't know, I've tried a ton of things and it doesn't want to play nice. It's not just a rounded corner rectangle, there's two half circles. i also need to put holes concentric to those circles.
I've seen old threads kind of about this, but they were doing the much easier and different thing of rounding the corners, not making two half circles at the end of a rectangle.
looks easy, but how do you start?I tried to create a constrianed rectangle then put fillets on the corners but every time i try to make the ends round, i get an error. even if i kind of get close to having a lozenge shape and try to draw 3mm circles at the origin of the fillets or end circle radius, it won't let me. this ended up more of a challenge than I saw coming.

You should follow tutorials. This is such a simple problem.
Look at the Chrisb book (in its signature) : https://forum.freecadweb.org/memberlist ... ile&u=5646 (https://owncloud.gwdg.de/index.php/s/eZ ... 9/download)

* Draw 2 lines + 2 arcs
* Select 2 points + Sketcher_ConstrainCoincident
* Repeat
* Select 2 adjacent lines + Sketcher_ConstrainTangent
* Repeat
* Select 2 arcs + Sketcher_ConstrainEqual
* Select 1 line + Sketcher_ConstrainHorizontal
* (Select center + axis + Sketcher_ConstrainPointOnObject)
* Select 2 points + Sketcher_ConstrainCoincident
* Repeat
* Select 2 adjacent lines + Sketcher_ConstrainTangent
* Repeat
* Select 2 arcs + Sketcher_ConstrainEqual
* Select 1 line + Sketcher_ConstrainHorizontal
* (Select center + axis + Sketcher_ConstrainPointOnObject)

you seem to have unlocked the mystery of this, thanks. will try now.
I honestly forgot about the arc tool.
i couldn't do it in Sketcher and I studied other threads and someone said "I don't want to make it out of primitives" and I didn't think of trying that so I tried it and now I'm printing the part.
and after trying Shalmeneser's genius strategy of using arcs (instead of trying to use 2 adjacent fillets) i got the result to the left in this pic:

Yes, that's what the forum's wiki tag does. Sorry, I had missed your post due to tab open for too long.

Wow someone created a tool for that. That was fast. Now that's what I call service, thanks Devs!
why does ignorance hurt so much while it's being removed? Thanks

@rek, the tool has been there for some time...
Also, note, if you ever change your signature because you change your hardware, it chaanges in all previous posts...thus any significance the specifications might have to old posts is lost for posterity.
