Re: Sketch is offset by small amount
Height must not be related to the radius.

Re: Sketch is offset by small amount
Just for another take on how to do sketches...
Part object is not required.
Fewer constraints (thus faster for the solver), easier to read, easier to update...

I'm not sure why that extra point is there. It's not supposed to be, and it's gone now.Shalmeneser wrote: ↑Wed Jan 19, 2022 6:42 pm Height must not be related to the radius.

Re: Sketch is offset by small amount
I put the Part object in because I thought I might need it in the future.
I'm not sure cutting the sketch in half and mirroring it works for me. I like seeing the whole thing in the sketch.

Isn't that result of constraint preserving fillet? Point lies on both original edges.Shalmeneser wrote: ↑Wed Jan 19, 2022 6:42 pm Height must not be related to the radius.

Just a suggestions on efficient workflow (and how things work better in FreeCAD...). You are welcome to do it anyway you choose.dcschooley wrote: ↑Wed Jan 19, 2022 7:31 pmI put the Part object in because I thought I might need it in the future.

I've only been doing CAD for nearly 50 years, it's probably made me daft...I'm just an old crazy guy.

Re: Sketch is offset by small amount
This point is on the 2 lines. (It's the second fillet tool : keeping actual constraints.)dcschooley wrote: ↑Wed Jan 19, 2022 7:28 pm I'm not sure why that extra point is there. It's not supposed to be, and it's gone now.

Re: Sketch is offset by small amount
I don't doubt that it is better, it's just a matter of getting my meager mind to work that way. How noticeable a difference does it make in terms of FreeCAD working better?drmacro wrote: ↑Wed Jan 19, 2022 7:35 pmJust a suggestions on efficient workflow (and how things work better in FreeCAD...).

Re: Sketch is offset by small amount
As for the Part object, unless you intend to create a quasi-assembly, it is just superfluous for a single solid.dcschooley wrote: ↑Wed Jan 19, 2022 8:13 pm ...

As for sketches and constraints.
Sketches should always strive to be as simple as possible.
The solver work increases with each constraint you add, and not linearly. It also increases the likelihood unexpected behaviour by the solver. It solves the equation sequentially, and takes the first valid solution. That solution may not be what you desire, so the constraint scheme is important.
By using the symmetry of the part, it is easier, quicker and less prone error to make a change to the geometry, because you only need to change it in one place. So, something with an 8 hole bolt hole pattern can be changed in 8 places simultaneously if you have sketched just 1/8 of the shape.

Re: Sketch is offset by small amount
so you can use Sketcher_External with less fear of TNP (check my file).
