Ability to cancel a calculation: an error can be costly!

Hi boys and girls, I hope the confinement is as pleasant as could be and that all ya'all are safe and sound in these current "interesting" times. I have been using my time wisely getting more up-to speed with the current state of path and...boy has it grown. It's almost overwhelming. Speaking of gro...

Re: What is the smarter way to mill this???

Hi hi friend, cool little project. PITA Hole selection : the pocket based on faces, should allow you select only the top face and process everything except the perimeter. This should allow the op to mill everything. Too much travel: With the most recent dev version (to which I do not have access at ...

Re: Coronavirus mask?

I see. In that case, insulation foam panels can do the trick (probably laminated into 2-3 plies depending on what thickness you're able to find out of hand). It's building material that's bought by the square meter, also used in model making (airplanes, decoration...etc). The advantage I can think o...

Re: Question: 3D Surface - DropCutter - Offset pattern, does it make sense?

Actually if you have access to both fixed height step or fixed lateral shift, you can probably mix an match with computationally less expensive rules.
Then again, i'm no wizard and what I suggest may be much more complicated than I think. Probably is.

Re: Coronavirus mask?

I still believe the whole endeavour will be more efficient and less expensive if you 3D print it. Machining a mask (thin and 3D) is already a difficult task (not to mention ludicrously wasteful) with rigid material. With a compliant polymer, you are just asking for hours upon hours of trying until y...

Re: Separate 3D Surface and Waterline (new feature) [Merged]

Well done to the team! There are really exciting things!

As soon as the nightly build is up, I'll give it a shot.

Re: Question: 3D Surface - DropCutter - Offset pattern, does it make sense?

As I understand the problem with this model is that the upper paths are too close together, and the bottom paths to far apart? So, the lateral shifts are what you want to be constant? Would it be okay then, if the depth varied as the cutter moved around the offset path? I'm just trying to both conc...

Step file size too big

Hello Freecaders, I am wondering how exactly FreeCAD does this: - I receive a rather complex .stp file in FreeCAD that is about 3 MB in size. - I remove parts of it. - I export it as step: and it is now 10 MB. In short, I feel like FreeCAD exports .stp files a lot bigger than I feel it should. Perha...

Re: Question: 3D Surface - DropCutter - Offset pattern, does it make sense?

Well it's equivalent to using a small ball end-mill. The path that i produced was technically for a small end mill. The problem in that case is that waterline will not detect surfaces that are close to horizontal (i.e. center of a gutter). But waterline is the only approach that follows the contour ...

Question: 3D Surface - DropCutter - Offset pattern, does it make sense?

Hi, I've been playing around with 3D surface to machine gutters and I have found issues that apparently neither waterline nor dropcutter in their current form will solve: In the screenshot , you will notice that the central area at the bottom of the gutter is left so to speak "unprocessed". In addit...
