September 29, 20215 yr comment_6048 Hi, I cannot determine the mounting surfaces automatically on this block. I extracted it from a bigger roof drawing, since it somehow doesn't seem to work, while I can't see what is wrong with it, with other similar blocks it works fine. See also screenshot attached, the right roof works fine, while the left one (the .obj created from the .dwg attached) somehow doesn't work. Can you tell me what is going wrong here? Thanks, Wouter Only1block.dwg only 1block.obj Report
September 30, 20215 yr comment_6051 Hi Wouter, The "determine mounting surfaces automatically" function is in beta so I suspect that there can be any number of reasons. I don't use that function myself, I simply draw the mounting surface on imported models since I find it more reliable and precise. Although I am wondering if the "plane tolerance" might have something to do with this. Maybe if you increased it it could work? But I'd just draw it manually since that should take about 10 seconds.

September 30, 20215 yr Author comment_6052 Hi, yes, the function for sure isn't as straightforward as it should be. I've spent a lot of time in getting the models made and exported in a way that the function works in PVSol. Now I usually manage to make it work, just why this simple "one surface" model isn't working bugs me, cause it is exactly the same as others that do work, except for the dimensions. Plane tolerance is there to merge planes together, so shouldn't have any influence on this one. Report
September 30, 20215 yr comment_6054 Can I ask why you're using the automatic function and not the draw tool? Report
September 30, 20215 yr Author comment_6055 Hi Jimmy, I'm aware of the function. But we have a perfectly accurate 3D model already created, which should not need the manual draw tool. If I'd start from a 3D mesh from drone data or something like that, I'd use that tool. (Or in case the software doesn't do what it should, but then I'd rather find out why first, as I'm doing here.)

September 30, 20215 yr comment_6056 So, I downloaded your model and tried to automatically determine the mounting surface. The model was acting really strange when I tried to activate it and going to a side view instead of a top view. So I tried to tilt the model backwards to see if that made any difference and I was able to place the models on the "roof" (which was now the side of the building). I then removed the module array and tilted it back to its original position. So. I was able to automatically determine the mounting surface on the roof. The issue is that the mounting surface ends up being on the inside of the roof. Here are the panels on the roof, clipping through the roof from the inside and upside down. And here's a view from the inside of the building. I think that this can be fixed by making the model a solid or increasing the thickness of the roof but I don't know that because I can't get the model to work in Blender. Hope that helps you a bit.

September 30, 20215 yr Author comment_6057 Well, you have exactly the same issues as I have. As to the solution, the model is already a solid, as you can see in the CAD. I uploaded another simplified CAD, with the neighboring roof. You can see both solids are exactly the same type, only one does the job, the other one doesn't. 2objects.obj 2objects.dwg Report
October 4, 20215 yr comment_6065 Dear Wouter, dear Jimmy, we really appreciate how you discuss with each other and help you out! Could you try to reduce the model so that only the lower block remains and then convert it into an obj file? Which software are you using for modelling and converting dwg to obj? Kind regards, Martin Report
October 5, 20215 yr Author comment_6071 Hi Martin, that is already added in the first message I put here. Model in Revit, converting in 3dsmax. Please have a look and let me know why it doesn't work. Gr. Wouter Report
October 5, 20215 yr comment_6072 Dear Wouter, thanks, I didn't realize that you already posted the model. I forwarded it to our 3D team and the hotline. Let's see what they say. Kind regards, Martin Report
October 5, 20215 yr comment_6076 Hi Wouter, our 3D team checked your model and it seems to be fine. Apparently there is a bug in the automatic detection of the mounting surfaces. We will file a bug notice with your model attached to the responsible developer so that he can fix it perhaps. But since he is busy right now with other things, and since it is a feature in beta state, please understand that there won't be an immediate fix for that. In the meanwhile we recommend to use the draw tool in those cases in order to get clean mounting surfaces. Kind regards, Martin Report
October 5, 20215 yr Author comment_6077 Hi Martin, ok. Thanks for the information. brgds, Wouter Report
