That pops up a dialogue in which you can give your component a name, set its axes, allow it to Glue to a surface, and if desired, cut a hole in an existing face to which you can glue it.Īlso, make sure that the bottom left checkbox is ticked - Replace selection with component. The easiest way to create a component (and I almost always use components rather than groups) is to highlight the geometry I want to make into a component (usually by triple clicking what I’ve just drawn, or perhaps by a selection window), then press the letter ‘g’ on the keyboard. You were probably trying to push pull the cylindrical part, not the end ring, when you got the message ‘you can’t pushpull a curved surface’ It was a very short section of cylinder just to the left of the thin ring, which stopped the thin ring being push pulled to the left more than a very short distance. Obj =, it only looks reversed from the inside. # collada library can triangulate on the fly Start = tuple(map(float, line.vertices))Įnd = tuple(map(float, line.vertices)) # Read the unitmeter info from dae file and compute unit to convert to mmįor geom in ('geometry'): Both these objects accept a mesh as base, and will take care of the conversion themselves.Ĭol = collada.Collada(filename, ignore=) If you use walls or structures, there is no need to convert the mesh first. Pretty useful for simple architectural objects. If you use the Arch tool (Arch->Utilities->Shape from Mesh), an additional algorithm is used that collapses all coplanar facets into one face. If you convert meshes to shapes with the Part tool, each triangular facet becomes a face. Once you have a mesh that has no manifolds at all, the chances are high that it'll convert to a valid solid. Blender has very good tools to detect defects in geometry, one of the most useful ones being the Ctrl+Shift+Alt+M, that selects all manifold edges of a mesh (all edges that are not shared by exactly 2 faces). SK (even the free version) can export to collada directly. That's the most important recommendation, and it's not always easy in SK, because it tries to hide the internals of your meshes from you. If your meshes are not solids, there is little you can do with them in the Arch workbench. A couple of methods and tricks that I use often: The main problem is indeed that not all meshes are solids, and even if they are, topology problems can often create problems further on. Make each a component, then radial array them from the centerpoint that you marked 23 x. keep one triangle and one square and delete the rest. Maybe I'm to tired to find the solution, but is there a way to set custom axes for projection and sections, or should I rotate all the objects to align them to the standard axes? Make this into a group and truebend 360 deg and 48s. Section planes could be non-parallel to the main directions of the building, too. since in sketchUp you can geolocate the project, the model will be offsetted and rotated, so the 2d drawings obtained by the orthogonal projection command could be non aligned to the front/side of a building.it could be useful to transform the parts into solids, but sometimes meshes in SU are not intended ad solids.selecting all the parts and create a container for them is also easy (from GUI at least).I saw that all the faces are triangulated, even simple rectagles are converted into 2 triangles. with the parts workbench I can easily create a part from meshes the automated way would take care of removing the meshes after the conversion.is there a way to do it all at once? (Assuming the original sketchup file is well formed) with the mesh workbench I can analyze and repair one mesh at a time.a simple script could do this automatically Open the collada file contained in the kmz exported from sketchup. These are the step I've done so far and the issues/observation While I'll try to move to another free/open source sketching program (yorik's tutorials of architectural workflows with blender and freeCAD are amazing and inspiring), in the future I'll continue to get sketchup models from third party (easier for a non techie user), so I'm trying to set up a good workflow (maybe a script?) to take care of the translation and have a good 2D output. I have a Sketchup architectural model and I would like to be able to getting the 2D drawings out of it, but I have only the free version of SU (can't afford to pay the pro version now). First of all thanks a lot for this software! Still trying to getting my hands dirty, but for timing issues I have to ask you directly some advices.
