I recently started playing around with rhino and GH. I want to make some Christmas presents for my parents- candle holders. I have attached the model.
I want to 3d print them but beforehand I want to know what the volume of the shape is. After modelling it in Rhino I opened GH, typed Geometry and selected the shape. Afterwards I used the function Volume but it turned red saying that it is an open brep. Is there a way to find out where the problem is and can the problem be with GH (well by GH I mean me)? Is there another function to which I can assign the geometry and another way to find the volume?
Well put it simply I did a cylinder, carved out the space for the candle, afterwards i did the triangles, rotated them accordingly and then polar arrayed them. In the end i did Boolean union. I think in GH will be very easy seeing what people are doing, but I can’t really do it.
