Re: Request: enhancing the retrace (external geometry) in the sketcher

That's an issue i have when creating a circle in a sketch, i can't reference it if on another plane looking directly vertical to it. Not even the center. This would be very nice. As it is now, i use a "dummy" sketch where i draw the circle but also a diameter of it so it can be referenced.

Re: Part compound vs. Std Part

Thanks for the very detailed answer. I love being wrong, best way to learn.
And then there's attachment offset too now... I'll go read up on that and get back to you with something smart.

Regarding your last statement, when i create a body (object) does it not automatically create an LCS with itself?

Re: Part compound vs. Std Part

You're right, it's not unclear from a functional point of view. It is mostly my own ignorance of the arcanes of Local Coordinate Systems, and some few details missing in the wiki. If I now understand right, in FreeCAD there are only two ways to move an object. Please correct if I'm wrong: 1. Through...

Re: Position of a .step file and references - Manipulator vs. Transform

Hello guys, Thank you for helping, @openbrain: i could try one of the assembly workbenches, but what I want to do is design parts that are adapted to the step files. So at the core, I want to design. @easyw-fc: I have seen this great Manipulator tutorial of yours, but sometimes, using the aligner to...

Re: Position of a .step file and references - Manipulator vs. Transform

Dear Openbrain, thank you very much for a very interesting screencast. Unfortunately while a great example of defeaturing (i had no idea Part had a direct defeaturing command, i thought it was only in defeaturing workbench), it does not answer my query exactly. Indeed in my case I'm importing severa...

Re: Part compound vs. Std Part

I find interesting that this discussion should appear today. It seems quite unclear to me exactly what actually moves and what doesn't in Freecad. More precisely, it seems quite unclear whether a movement command will displace an element relative to its own reference (LCS) or will displace its refer...

Position of a .step file and references - Manipulator vs. Transform

Hello everyone, I know this question has been asked several times and there are discussion about how to modify the situation, but here I'm at a loss. - I have a step file imported from a manufacturer. - I need it aligned to a master sketch I have produced, so that the face of the step of file can be...

Re: Complex pocketing?

At least in my case i can say that the simulation is only a check. I never use it as a way to optimize.

However you are right, the solution i presented was almost solely the result of having to do without rest machining.

Re: Complex pocketing?

Yes i agree. Step 3 in my original suggestion is best performed using adaptive followed by Step 4 profiling to accurately and nicely finish.

Re: Complex pocketing?

I just had some time to look into the model. There is no shortcut to this task. In my opinion: 1. Face milling of each Drilled Post. With adequate positive "material allowance" value to make sure you make a nice platform there. 2. Drilling of each hole. 3.Then normal pocket milling of the bottom. Wh...
