003 - Blender & Freecad Arch Workflow - Windows

[@oalfernandes]

Thanks for your videos! You are amazing!

I will go with this workflow, freecard is so hard to model, blender is fast and I do not want to relearn modelling inside freecad I am just after the documentation . Thanks for sharing !

I understand

Holy Crap! That was painful! Are you saying that you can't model windows in 3D in Freecad and so you need to export the basic structure, build the windows in blender and then import them back ? I didn't actually even see where you switch to blender... poking around it looks like FreeCAD throughout Can't you just create a sketch on the face you want to put a window into, and "extrude" a rough-opening hole into that wall ? In SketchUp I would first build the window frame with specific dimensions related to available window sizes. Turn that into a component - labelled according to windowframe type and dimensions Then draw the glass in place on top of that component (rectangle inferenced to the window frame opening, extruded, and made that into a glass component) and then select both components and make a window_assy component An alternative technique is just to position one or more window assemblies onto a solid wall, and then open the wall component and intersect-with-model and then delete the new faces created by the intersection lines. Boom! Done. All of the low-level uglies are automatically taken care of. This example seems to be working at the atomic level where one needs to be continually paying attention to orientation and solidification, and re-copying edge-loops... This process you have demonstrated appears to require a very detailed high-level mastery of many FreeCAD concepts, operations, states - just to bang a window into a wall

Hello @Kurt Klingbeil, No i'm not saying that you can't model windows in Freecad. This is a demonstration of how to Model from Blender and export the model the Model to Freecad for greater reliability, since blender is a mesh modeling software, and freecad is a Solid modeling software, so solid modeling tend to not like certain effects within Mesh modeling programs and so to avoid having too much cleaning up in Freecad, you need to model using various techniques. Ofcourse this is so until open source programmers have enough time to invest in creating a much cleaner export language from Blender to Freecad. I do show how to switch from Blender to Freecad. As far as the sketch face in Freecad for the window, you can check out the Freecad Architectural modeling 03. It is still quite raw and Freecad has substiantially evolved since the video was last made. I don't use Sketchup here as i was promoting open source and Sketchup pro is not open source.
