Re: Diagram Workbench: general object-based diagraming and MBSE

ping Started experimenting with virtual disk interface to database. I use fusepy python library on Debian. Now I managed to generate fake filesystem with some files and directories. And I edit one file in one folder, save data in my variable, then open them as other file in other folder. It works p...

Re: derivatives madness

There is some problem with "normal use-case" definition. What is normal for one, can be abnormal for others. Use cases looked for me normal year ago today look not so normal, and vice versa. IMHO every feature request contains useful ideas for development and for workflows we can not imagine now. As...

Re: Toy servo motor

As a hobby I developed (not fully yet) python-based electronic/physics educational kit... Very impressive. Were the parts in the images modeled with FreeCAD? Which version, Part or PartDesign workbench, and which assembly workbench? Top down or bottom up assembly? Yes, this all was FreeCAD 0.18, bo...

Re: Another approach to assembly solver (A2plus)

So deep integration with PG would be great! :) Hope to see it one day. However for experimenting with new database-centered workflows we need very modest level of integration: just ability to somehow keep and retrieve FCStd file contents in database records with some custom fields. 1. It seems that...

Re: Diagram Workbench: general object-based diagraming and MBSE

I see, if I understand it correctly this goes more in to the PLM... For example, if we can dream a little, lets imagine something like GitLab as a central database but developed more specific to support product developments, supporting MBSE models, Modelica, simulations, 2d and 3d CAD data, FEM/CFD...

Re: Diagram Workbench: general object-based diagraming and MBSE

I see. I do not try to embed Modelica-style modelling into FreeCAD. Note in those videos that both MBSE requirements and Modelica model are linked in to the 3d model and checked, but of course not the complete MBSE model and not all the Modelica simulations have to be linked just those parts that m...

Toy servo motor

As a hobby I developed (not fully yet) python-based electronic/physics educational kit. For mechatronic experiments I needed servo motor with position and torque feedback and customizable parameters, easily fitting into popular brick constructions... Two hall sensors and magnetic ring are used for p...

Re: Diagram Workbench: general object-based diagraming and MBSE

MBSE by itself in general actually represents just the first part that one would do for example in Papyrus, the big idea however is of course that all of it would be connected, so for example if you would have a requirement that only one type of bolts should be used in the product and you would use...

Re: Diagram Workbench: general object-based diagraming and MBSE

Well you have shown some remarkable projects so I was thinking you could use some remarkable tools ;) I will have to look at Archi and your diagram in the other topic a bit more closer before I will be able to better understand your idea how you would like to do this. Personally I am very much look...

Re: Another approach to assembly solver (A2plus)

For spatial and geographic data there is PostGIS, a PostgreSQL extension: https://postgis.net/ A while back I thought it would be interesting to wrap OpenCASCADE functionality in a PostgreSQL extension as well; then PG servers running that extension could serve as model backends for FreeCAD, and yo...
