That sounds like a good idea. I tried to use a line as reference not a plane. I couldn't reference a line so I gave up on that

Re: PartDesign: Mirror along X and Y / Point Reflection / Multitranform but only keep result

I mean something like this: https://upload.wikimedia.org/wikipedia/commons/thumb/5/57/Cyclic_symmetry_2.svg/220px-Cyclic_symmetry_2.svg.png I found a solution myself in the meanwhile: I used the PolarPattern and just rotated the pocket around the center. Still I'm interested if this is the common ap...

[Solved] PartDesign: Mirror along X and Y / Point Reflection / Multitranform but only keep result

Hello FreeCAD community, I'm in the PartDesign module and want to mirror a pocket along the x AND the y axis at the same time (point reflection through the center) PartMirror doesn't have that option so I tried Multitranform. But Multitranform keeps the in-between steps. So at the end I have three p...

Re: CNC Machine with built in radius compensation

One thing I would have you think about is the number of path points at sharp corners, whether you are doing an arc around that corner or if you are cutting past to tangent for the next cut. If you have the system generate a number of points which all end up on top of each other, your control might ...

Re: CNC Machine with built in radius compensation

Thanks for your posts, they really clearified things for me. I find it most useful to not use CRC at all and use Path to do all offsetting. I only make one-off and small run parts so that works for me. If I need to adjust the offsetting value, it's easy enough to change the tool in Path and re-post ...

Re: CNC Maschine with built in radius compensation

The Path commands are not recomputed at postprocessing. They are only sequenced and converted to the final gcode. Ok, but since prostprocessors are python code it sould be possible to manuelly recompute the path, right? But I guess this is not how it was intended and probably difficult do. What you...

Re: CNC Maschine with built in radius compensation

Hi Herbert, yes, but that's not quite what I want. During design I want compensation to be active zu see how the path will look like and to have a proper simulation. Only the code for the maschine should have no compensation. For sure, i could uncheck before postprocessing and than check again. But ...

CNC Machine with built in radius compensation

Hello Everyone, I'm working on a postprocessor for our SCM Record 110 (xilog based) maschine. This maschine does not read g-code, but it's own type of instruction which is inpired by g-code but more advanced. One of it's features is a built in radius compensation. Meaning codes have a parameter R th...

Re: Splitting a complex sketch into smaller parts

Thanks for your responses This is not correct. It allows selecting of real (not construction) edges of other sketche Ok, I tried that and out it worked :) . I don't no why I came to the conclusion that sketches couldn't be referenced, maybe something else was wrong. This however solves the problem f...

Splitting a complex sketch into smaller parts

Hello everybody, thank's for making FreeCAD, I just started using it and really like the parametric concept and "python everywhere" approach. I'm struggeling with the following: I have a model with ~12 pockets and they are all pretty much depending on one another. Therefore I put them all ...
