Greetings to the whole FreeCad community!
The following guide has already been published in the Italian forum:
At the invitation of Kuda1 (which I thank) she was transferred here by:
https://forum.freecadweb.org/viewtopic. ... 41#p415641
and translated into English.
I read, scrolling through some posts, that some "FreeCaddisti" ask if FreeCad has or will have the possibility to export to pdf, in fact it can, but not in 3D (we hope that the developers will give us this possibility in the future).
A few years ago (2014) I had published, on the website (free computer science) of the legendary Ing.Prof. Cantaro (unfortunately [:(] no longer with us), a step by step guide ... on how to obtain, with relative simplicity, a 3D in PDF starting from a CAD file (like FreecAD) and / or from a 3D modeler (like Blender) in * .stl format, through the use of free software and / or with an open license, I thought I would do something pleasing to the whole community, proposing it again.
I specify that the guide consists of four pages, the last of which represents a trivial example of the 3D pdf created using the procedure.
It is easy to understand, in fact, step ... step and accompanied, for further clarity, by images in addition to the description of the procedure.
To view 3D PDF files, you need to open them using Adobe Reader or other software that can read these 3D PDF files.
To activate the 3D of the last page (appears with the writing "stlTOu3dTMP.u3d" in the center of the page) click on it and give, if requested, any security authorizations, adobe reader will automatically add a toolbar that will allow movement, zoom, measurement, etc. of 3D.
I also attach another three discreetly complex 3D PDF files obtained with this technique to demonstrate the level of completeness and power of the sw used and indicated in the guide: the first is the structure of a spiral staircase, in "wrought iron "With full sections, complete (already built in practice), the second exploded view of a frame of an extractor hood for domestic kitchen (in practice already built) whose component parts, in pre-powder coated steel sheet, from 7/10 thick, they were made with a cnc bending machine, the third the overall of the same frame.
P.Š. it must be said that the procedure (through the use of the sw indicated in the guide), does not allow the export of texturizations and / or colors ... but to us, technicians, designers-planners, engineers, etc. in the mechanical field we are "little" interested ... .. but probably not so much to architects.
I hope the translation has been good (?)
I wish you happy reading, but above all good work!

FINALLY (!!): - BLENDER is supported by FREECAD a C.A.D. FREE PARAMETRIC 3D and worthy of this definition (!) Which together with GIMP, INKSCAPE and LIBREOFFICE, to name a few, can make it possible to transition to Linux in a stable manner, without having more "frustrations" and / or second thoughts ....... even in the professional field!
