What I usually do with grasshopper in Rhino with complex projects is intersect a plane with geometry i want to read as cut line ones (e.g. walls), intersect the plane with geometry i want to read as medium again, and do more intersections, if i want more lineweights. However, i suspect with intricate geometry, this physical intersection approach could be quite expensive in terms of computation time.bitacovir wrote: ↑Fri Jun 28, 2019 2:59 pm
For the Architecture Industry, to produce so many drawings sheets of a single project can be a difficult challenge for FreeCAD (I am thinking in TechDraw WB).
Maybe an interesting approach is to think in metadata rather than graphics render on drawing sheets. Some kind of metadata system that FreCAD could storage and produce uncountable automatic technical reports when is required.
Another possibility is for 3d object to have draftwork attached to them so that when there is a plan and section cut, the, parts have the option to display 2d draftwork instead of 3d geometry. We do this quite often for representation purposes with Revit, and I have even found myself doing a similar process in rhino with replacing 2d with 3d blocks. I haven't yet explored whether it's possible to attach 2d linework to a 3d part in freecad yet...
Thanks Yorik!yorik wrote: ↑Thu Jun 27, 2019 3:14 pmOf the "big problems" I see of using FreeCAD for BIM (working with large files and producing 2D drawings, basically), the first one is in large part solved by working with Arch References (we still need to make IFC import faster), and the second one I still have no clear idea how to best solve, it needs more testing...
Yes, I agree. Mostly in Revit, we draw in plan view, so being able to easily switch from one plan view to another would potentially help a lot. And if there is a way to preview printing settings, including fills, it would become much more usable.
Besides 2d drawings, another limitation is ease of use of working on top view plan sections of each floor, and switching easily between the different levels. Even when working on some of the most complex projects, we spend the bulk of time working in plan instead of 3d. I've done the theatre model mostly in 3d and isolating an initial axis to draw more accurately in 2d.
Now, I am working on a small extension in feet and inches, and I am catching a few bugs. If i have my units set to US archiectural, when I import a dxf, it doesn't come in the right scale. Also, when I am drawing lines, the visible dimensions seem to be mm instead of feet and inches.
And last bug for the time being seems that when i enter a number for the floors, it doesn't quite like it and enters a new number. Also, if i click in the position z box, and then click somewhere else, the number is automatically adjusted, without a reason, it seems
