Hi everyone I am working on a very old project and the roof tiles are very unusual and there is no tile like this in the Archicad accessories addon. I tried to model it with a morph and finally turn it into an object, but eventho It is an object, it becomes very heavy and I can no longer work on the project, does anyone have any suggestion? Except for GDL coding...
Hey Barry, thanks for the answer, I have attached a photo. They need these tiles to be visible in 3D so I cant use 2D stuff or textures, but havent heard about profiled shell, you mean modeling 1 tile with shell then copying that?
This should be doable, depending on the level of detail you need.
I would suggest modeling one tile as a morph, using as few polygons as possible. Could you use a single, flat shape with no thickness? This alone will reduce the amount of polygons needed by more than 50%. Keep detailed curves to a minimum, use straight line facets instead.
Look at the attached quick sample I made – this roof has 1120 tiles, each modeled as a single layer (no thickness) morph, 7 polygons each. To make this I drew the profile in plan, traced it with the morph tool using straight lines, and then a little manual work in 3D to extrude it, before multiplying it and unifying them into one large morph. I believe this last step is important – it reduces the number of individual objects Archicad has to keep track of.
The total roof (one side, 14 x 4 meters) amounts to 7840 polygons – that should be workable on most computers, at least it is on my 2013 iMac.
Of course you could end up with many times more on a large building, but I think this is about as efficient as you get without coding. I have not tried to convert it to an object, this could increase performance even more, but I have generally not felt the need to do so.
Thanks David, very cool suggestion; but how about sections, where you need them to have a thikness? I have almost 7500 tiles, so with the thinkness and extra lines, I have atleast 75000 lines at the end, big difference indeed
