Optischer Schnitt durch Baugruppe, z.B. für Ventilgehäuse
Re: Optischer Schnitt durch Baugruppe, z.B. für Ventilgehäuse
Hi
thank for upgrade the macro make by aleph0 (and not mario i ave just add one feature and Sam correct for the 0.17 FC version)
but i have error see Sezione Dinamica
and with your modification: first test and after same correction Sam FC stop with the same error window
(ps: the original version does not work anymore ??)

Maybe you need a special feature, go into Macros_recipes and Code_snippets, Topological_data_scripting.

Re: Optischer Schnitt durch Baugruppe, z.B. für Ventilgehäuse
Dear Mario,
thank you for your answer. The original macro still works, but without colours.
@Gift changed the macro and it worked if the parts do not touch each other, please look at this picture:
If the parts are touching each other, the colour from the cutting plane is wrong, and the face is melted into one, no single faces with the part colour, please see this picture:
Is it possible to optimize the macro?
Thank you and best regards
Wilfried

hi freecad-heini-1
I think Gift is more competent than me
@Gift
the upgrade is finished ? (for update the wiki page)

Re: Optischer Schnitt durch Baugruppe, z.B. für Ventilgehäuse
Thx 4 your trust. No, the upgrade is not finished. I'm going to revise it. But now is the time to drink beer.
Re: Optischer Schnitt durch Baugruppe, z.B. für Ventilgehäuse
1. If I replace MultiFuse by Part::Compound, is the fusion issue solved. => Part_compound.png
2. But multi-color-objects falls to anarchy. => Anarchy.png
3. The very next step is to cut all objects with Part:Cut. The cut face will dye another color(selectable). Is this solution ok? => A_lot_of_PartCuts.png, A_lot_of_PartCuts2.png
I need more time…
kind regards Benjamin

Re: Optischer Schnitt durch Baugruppe, z.B. für Ventilgehäuse
A update to test.
Todo:
* optimize the loop (initialize some objects out of the loop)
* some error messages with outline
* cut object: “Cannot compute Inventor representation for the shape of Compound”. Maybe some very empty shapes?

* This widget makes an interactively moveable cross-section of the *
* currently visible objects in the currently active document. The *
* cross-sectioning plane is specified by its normal, and the cross- *
* section can be moved along that normal using a slider bar. It can *
* show the cross-section either as an outline or a view of the sliced *
* objects. To run the macro, first download it from this site and *
* install it in your macros directory, then use the menu to call up *
* your list of macros and double-click on this one. It will display *
* a default cross-section and pop up a window to enable you to set *
* the cross-sectioning parameters. Closing the pop-up window will *
* restore the scene to its previous state before the macro was *
* started. *

Maybe you need a special feature, go into Macros_recipes and Code_snippets, Topological_data_scripting.

Re: Optischer Schnitt durch Baugruppe, z.B. für Ventilgehäuse
Funktioniert bei mir leider nicht. Dennoch vielen Dank für die Mühe.Gift wrote: ↑Wed Sep 06, 2017 3:02 pm A update to test.
Todo:
* optimize the loop (initialize some objects out of the loop)
* some error messages with outline
* cut object: “Cannot compute Inventor representation for the shape of Compound”. Maybe some very empty shapes?
