Re: Curved Shapes Workbench

I changed the distribution for sinusoidal as Vincent B proposed (high density at the start and end) and added asinusoidal (high density in the middle) sinusoidal: https://github.com/chbergmann/CurvedShapesWorkbench/blob/master/Examples/CurvedArraySinus.jpg?raw=true asinusoidal: https://github.com/ch...

Re: Optics Workbench

Now I found out that the fan of rays (2D spherical beam, for example Nr columns 50, Nr Rows 1, Cone angle 20, Spherical true) points always along the X-axis and rotating the object does not change the beam direction (remember to Recompute the object). Also the nominal pointing direction of the 2D a...

I added this feature. Thanks you for the hint.
Furthermore I fixed the calculation of the number of rays in a 3D spherical beam.
Please update the workbench.

Thank you for digging deeply in the code and for showing a workaround for this problem.

Re: Optics Workbench

I was thinking that it might be useful to have the ability to 'ignore' some optical elements on a per-lightsource basis. nemoandrea added a new feature to the OpticsWorkbench. Every Ray or Beam now has a property "Ignored Optical Elements". You can select mirrors, lenses or other optical ...

Re: Frage zu Vorlagen für Laserplotter erstellen / Arch Panel

Um die Sache zu vereinfachen hatte ich mal das Makro LasercutterSVGExport geschrieben. https://github.com/FreeCAD/FreeCAD-macros/tree/master/TechDraw/LasercutterSVGExport Aus einem mir unbekannten Grund ist es aus dem Addon Manager rausgeflogen, aber man kann es runterladen und manuell installieren....

Re: Creating SVG Export for lasercutting

Why does this macro does not show up in the Addon manager any more ?
The code is still located in https://github.com/FreeCAD/FreeCAD-macr ... r/TechDraw

Re: Optics Workbench

I cannot reproduce this and downloading your example fails.
But this behaviour could be caused by a rounding error when the rays are lying not exactly inside the same plane as the mirror sketch.
Try to extrude your sketch into the third dimension in both directions.

Re: Curved Shapes Workbench

Hi, With CurvedSegment, when changing the interpolation points parameter, I input "1" with the keyboard then "5" and "0" for 150 values, an error occur. And the Curved Segment is freeze, must be rebuild. :? The discreting process seems not like 1 as value? I fixed this...
