CalligaroV's Showcase

[calligarov]

Hello Everybody!

As this is my first post I'd like to introduce myself before diving into the topic:
My name is Vincenzo Calligaro and I'm an italian bachelor in Automation Engineering graduated at the Polytechnic School of Milan (Politecnico di Milano).
Until October 2021 I was an AHU&HPAC Unit Controllers Developer at MEHITS, then I left and tried to start my own business.

I'm also an occasional contributor of Open Source Ecology (OSE), you can find the link to my contributions in my signature.

As wrote above, I'm trying to start my own business about open source software/hardware, based on OSE's concepts, and therefor i discovered and started using FreeCAD.

As of now I made the 3D model of one of the 3D Printers built by OSE (and of other machines, but not completed yet )
The FCstd file is too heavy to upload here, but you can download it from my GitLab repository (all the parts are simple copies of the parts made with PartDesign) or from it's page on OSE's wiki (both the previous file and all the single parts made using PartDesing)

D3D Universal 3, made using the workbenches PartDesign, Draft (for placing the part in the assembly) and Fasteners.

Beside my contributions to OSE I made some tests of integration between MCAD (FreeCAD) and ECAD/EDA(KiCAD)
Following you can see my attempt to design an Arduino Mega 2560 rev3 board.
It's shared on Google Drive

Also, I'm trying to learn how to use the worbench Path for PCB Milling (and milling in general).
As before, you can find the original file on my Google Drive.

All the models I posted here were made in this last year, always using the latest version available (I compile it almost every day after pulling the latest commit )

Hello,
Really nice renderings! Did you encounter any difficulties to obtain them? And have you tried povray_studio_light template (there are black parts in your model, it might be more suitable)?

[calligarov]

Hi @howetuft!

Thank you very much for the feedback and even more for your contributions to the Render Workbench!
Answering to your questions:

Did you encounter any difficulties to obtain them?

For those renders I haven't had any issues, everything worked nice and smooth and didn't took me too much time to produce them
However I'm experiencing an issue with the rendering of mesh objects:

in the following file (downloadable from my Google Drive)

I get the following errors and I can't produce the render:

  File "/home/calligarov/.local/share/FreeCAD/Mod/Render/./Render/rendermesh.py", line 78, in __init__
    assert mesh.Placement == App.Base.Placement()

I can obtain the render if I add only non-mesh objects.
For me it's not an issue at all, IMHO the important thing is being able to obtain renders of parts/ojects designed with FreeCAD (or other CAD softwares and imported using "classic" CAD formats such as STEP rather then STL )
Probably the root cause of the issue isn't inside the Render Workbench at all but I haven't spent too much time figuring it out, as said before for me that's not an issue

And have you tried povray_studio_light template (there are black parts in your model, it might be more suitable)?

Not when I wrote the previous post (probably because I was a little bit "influenced" by the black TD template topic ).
But as you gave me the suggestion I just tried it and it's indeed nicer
These are the results

Hello @calligarov,

I can obtain the render if I add only non-mesh objects.
For me it's not an issue at all, ... Probably the root cause of the issue isn't inside the Render Workbench

Well, it is very kind of you, but it is a Render issue (an old debugging statement forgotten there). Or, more precisely, it was, because I applied a patch a few minutes ago.

Could you please update the workbench, retry your rendering with all the components including the meshes, and let me know? Many thanks in advance!

First of all thank you very much for the quick modification!

With the updated code that issue looks solved but now I get another error:

    if mat.Proxy.has_textures():

This time I tried to modify the code but with no success, I always get the same error.
Any guess?

Argh! I should have tested more carefully.
I've applied a patch, could you please update and try again? Thanks!

Sure!
Just tested, no errors this time, everything worked nice and smooth!

Well, I think we can say that the problem is solved (even if this wasn't a problem at all for me after all)

I'd like to thank you very much for your help!

Also, I'd like to thank again all the FreeCAD developers and especially, for this specific case, @yorik and all the developers of both Render and Arch workbenches!
The design of this structure and it's render took me less than 6 hours of work!

Cool!

Thank you, it is a nice show case of what one can do with FreeCAD resources only, without using other complex tools... Have fun!
