Basically, you are asking to switch the geometric kernel from surface to solids, which can only be done if you build from scratch. That won’t happen, I guess, as SketchUp is merely an AEC-modeller were most shapes are pretty straight forward. That said, it is still possible to create solids (with or without extensions) with more complex shapes by subtraction, trimming or deformation. They can become accurate when you have more segments, but they will still be just edges and faces, and will have inaccuracies. (ie. a circle can have a centerpoint and calculated circumference, but as soon as you edit it (merge with other geometry) that info will be lost and you get approximate area’s or total length of the segments instead of a calculated perimeter) A SketchUp solid is not the same as Nurbs-solid. That said, the watertight objects in SketchUp can have all sorts of attributes, one of them being able to recognize if it is a solid, so why not have ‘Substance or Resource’ being one of them. (I specifically do not want to use ‘Material’ because it refers to the all ready existing, which is only a cosmetic thing in SketchUp) Substance or Resource would be a new Class or Object in the API (not sure if I phrase correctly @DanRathbun) with attributes like the ones you use in the Periodic System.(Mass, E, Density, Stress, Coefficient of expansion) or heritage (Pine from scandinavie, steel from recycled bins) In SketchUp, we would use the Mass, primarily and heritage. Extensions could work out the others like expansion (eg. You set the geolocation, the date in Shadows and it picks the right temperature, so you can see how much your rail would expand) The ability to report would be by File-\>Generate Report, as it is now all ready (we can now only generate the dynamic component and Advanced Attributes) With the upcoming awareness of the limited resources, SketchUp could become more import in the process. > [@Better Solids and (hopefully) better fill](https://forums.sketchup.com/t/better-solids-and-hopefully-better-fill/62580): > > (The request is at the end! / fill with material) SketchUp Solids can be somewhat buggy. I would like SketchUp to treat watertight shapes with more respect before calling them Solids The program would benefit from doing so in more than one way. Solids need to follow certain rules (watertight, etc.) What is failing is the rule to have all faces in correct orientation. Basically there are only two types of solids: without or with voids: (the ones with holes through still have one surface: se… > [@Geometric Constrains](https://forums.sketchup.com/t/geometric-constrains/113178/6): > > My daughter was supposed to learn NX in a course last semester, and I was hopeless trying to help her. My impression was it was like me throwing my students into dynamic components on day one before even mastering zooming and navigation. Interesting concept and functionality that could be useful. Kind of like the graphic equivalent to formulas in Excel? > [@Bending a beam like having a force at some point](https://forums.sketchup.com/t/bending-a-beam-like-having-a-force-at-some-point/67730/9): > > you might wanna check Inspire 2018 from SolidThinking: besides Topology optimalisation, it can offer quick insight in how parts interact, apply forces etc. They also have a (free) webbased version to test: Though not common in architecture, the need for optimization and simulation driven designs in this field becomes more and more.
