![]() I use Solidworks for most of my modeling. There are different ways to model parts for dual extrusion, but 2 separate STLs are required. With dual extrusion we can just model the outer housing and inner bearing and print it out at one time with two different materials. The stock SLB has a printed housing, and then a bearing is slid in or pressed into the housing. For this project, we used the MadeSolid PET+ in opaque black in order to match the original printed parts. Printing temps may very slightly, but 240-260C with a heated bed at 50-60C is appropriate the range. There are a few different PETG filament options available - MatterHackers PETG and MadeSolid PET+ are the two we print with most often for functional parts. It also has a nice glossy surface finish. PETG is easy to print, has virtually no warp, and is about as strong, if not stronger, than ABS. We decided to use PETG for the outer housings. While ABS is a versatile and useful filament, it tends to warp, and that’s not ideal when printing things like bearings with tight tolerances. The stock Taz pieces were printed in ABS. Since the only part we need the Tribo for is the part contacting the smooth rods, we can print the housings out of another material. Also, the Tribo filament is on the expensive side of filaments. ![]() We don’t want these printed replacement parts to break anytime soon. The dirty part is purely a cosmetic issue and not a big deal, but we wanted our Taz to still look good after the upgrades. The Tribo glides on the smooth rods very smoothly and quietly, but it gets dirty quickly and it doesn’t seem as strong/durable as the ABS that the stock parts were printed in. There were a few things we noticed while looking at the printed SLB. The center hole was a little sloppy so there was a bit of play, but it confirmed that this material would work for use as a bearing. Two multipatch features.It came out pretty well for a first print. You could try editing the multipatch in SketchUp by the way of Collada then replacing the model when you are finished editing) ArcScene 3D Editor -> Replace with Model (This should be possible according to documentation but I have not tried.) Exactly how were they created? Can you provide some screen captures? (You might need to create more complex 3D solid object features in a 3rd party 3D drawing software as ArcGIS is very limited in this area. I suspect your polygon multipatches do not fully enclose a volume. Intersection also succeeded without errors. (See screen captures below) I then created some circular polygons, extruded them and converted them to multipatch features. Intersection succeeded without errors and produced expected results. I was also able to calculate volume of the spheres. I tried running an example with spheres and created 2 intersecting multipatch feature classes. Personally, I have not had a lot of success using "Extrude Between" with complex surfaces) (Unless you extrude between 2 TIN surfaces which should produce a closed multipatch. Multipatch features created with the Interpolate multipatch to polygon (using a surface) tool can likely not be closed. To close a multipatch feature, it must completely enclose a volume. It makes sense to use this function to group a collection of 3D polygon faces into a single multipatch polyhedron. ![]() In this case, what is the advantage of the conversion? If grouping by ObjectID then you will have the same number of entities - i.e one multipatch for each polygon. You can check whether the geometry is MULTIPATCH or POLYGON on the Feature Layer Properties -> Source -> Geometry. You report that your "output had the same amount of entities only they all were having the same geometry." It lists several other caveats why the conversion might not work. They have no fixed orientation that can be used for exporting. The position of these 2D symbols areĭynamically oriented to face the camera position in a 3D scene, so The Layer 3D To Feature Class docs for ArcGIS Pro state "[Marker One clue is that you are converting billboards. Without more information, we cannot be sure why it failed in this case. There are many reasons why 'Layer 3D To Feature Class'will fail.
