Another post in this SketchUp forum from a SketchUp employee suggests that numbers in the millions will create problems. ![]() My model in MeshLab has 1,082,867 vertices. Apparently Blender provides some sort of alteration or filtration that makes the model more pallative. I even saw a posting in this SketchUp Forum suggesting importing the Collada file into the open-source editor Blender and then exporting in Collada format and then importing into SketchUp. SketchUp just hangs and does not recover (even if left running overnight). I have tried exporting my model from Meshlab in Collada format and then importing into SketchUp. I export my model from ColMap into the open source MeshLab and it looks great. I’ve some samples of my models at: Work in Progress Samples - Court/Chemeketa Shadow Analysis for State Street Project adjacent to National Register Historic District Court-Chemeketa - Album on Imgur I think I have made good progress on this front and feel I can create such models of houses. If I can perfect a workflow that produces satisfactory results, I’d like to model the homes adjacent to the commercial district so the Shadow Analysis afforded by SketchUp can be more realistic. To that end, I’ve been experimenting with ColMap creating 3D models of my house and garage. I want to be able to create 3 dimensional models of a few houses and place the associated house over its footprint to make the model more attractive and simulate a view one might see from the sidewalk. This give me the ability to create 3D blocks and then see how the shadows fall. ![]() I’ve been able to import shape files for the tax parcels and the the building footprints. If you export the SketchUp model to a *.obj file and load this in the slicing software "ReplicatorG" you won't get any errors.I’m trying to create a Shadow Analysis model for the City of Salem, Oregon, in conjunction with their consideration of a downtime plan for a commercial district that is adjacent to a Nation Register Historic District that contains old residential homes. ![]() There is also a Plugin called "CleanUp³" for SketchUp which can clean your model, but in my case, it has not found all of the unnecessary lines. Here you find a post where the problem is also explained: ![]() Then export it to an STL file and voila the model is no more faulty. Use the wireframe view in Sketchup to find these lines and delete them until you have a clean model. The solution is to find these surfaces and the according lines which make these surfaces. During the design process, you will automatically create these unnecessary surfaces inside your model. The problem was, that I had a huge amount of surfaces inside the closed volume which make a faulty STL file when exported. This file I loaded into the slicing software "Slic3r".Īnd as you can expect I got a lot of errors.Īfter that, I used the STL Plugin for SketchUp to export a SketchUp project to an STL file directly, but I got the same sort and amount of error in my model after importing it to Slic3r. I created a simple "cable tie holder/mount" in SketchUp 2016, saved it as an obj file, loaded it in Meshlab and exported it there to an STL file. If you create 3D Models using SketchUp then export them some how to an STL file and load this STL file in a slicer you can get some or a lot of errors in your model.
