aheimann Posted May 6, 2019 Share Posted May 6, 2019 Hey everybody, I have a complicated topography in my plan, which is apparently too big or too complicated to export to IFC. Therefore I decided to divide this element into multiple smaller site models. When I export the file to an IFC project the exported file shows only one of the site models. Is it possible to export only one site model per file? Do I need to specify the site models in a specific way in order to export all of them at once? Thanks for your help. Kind regards, Anna Quote Link to comment

aheimann Posted May 6, 2019 Author Share Posted May 6, 2019 it takes about 12 hours to export it. Quote Link to comment
Vectorworks, Inc Employee Robert Anderson Posted May 6, 2019 Vectorworks, Inc Employee Share Posted May 6, 2019 What version of Vectorworks are you using to export, and are you exporting to IFC 2x3 or IFC4? Quote Link to comment
aheimann Posted May 6, 2019 Author Share Posted May 6, 2019 I have tried it in both. Unfortunately with the same result. Quote Link to comment

aheimann Posted May 6, 2019 Author Share Posted May 6, 2019 I am using Vectorworks Landmark 2019 SP3 for Mac Quote Link to comment
Vectorworks, Inc Employee Robert Anderson Posted May 6, 2019 Vectorworks, Inc Employee Share Posted May 6, 2019 How big is the file in Vectorworks? Can you post a copy of the VWX file? 1 Quote Link to comment
aheimann Posted May 6, 2019 Author Share Posted May 6, 2019 The file is 500 mb. I can not manage to reduce it to 60 mb in order to upload it here. Quote Link to comment
aheimann Posted May 8, 2019 Author Share Posted May 8, 2019 So, Robert Anderson continued his help per direct mail to me. In the end it turned out that my site terrain was just too complex. He used the "simplify 3d polys" tool on my imported topography lines and was able to reduce the size and therefore the complexity of the site terrain significantly. Thanks a lot again! 1 Quote Link to comment
Vectorworks, Inc Employee Robert Anderson Posted May 8, 2019 Vectorworks, Inc Employee Share Posted May 8, 2019 Glad to help, Anna. Often when default conversion resolutions are set to "high" or "very high" and you are importing spline data for topos, it's possible to get topographic geometry that can have 3000 or 4000 vertices for a single topo line on a feature. The site model works with the data it has, and doesn't simplifiy. This can bog down the model and also anything that depends on the model (like IFC export). You can reduce the vertices by a factor of 20 (and speed up by MORE than a factor of 20) with no discernible difference in the visual quality of the site model. That's why we have "Simplify 3D Polys" in the Terrain menu. Again, glad to help! 1 Quote Link to comment
