    Rounding Question

    The easiest approach is to start with a box. You offset edges, then move the points to pull the shape to match your design. I'm not a great teacher but William Vaugan's ebooks are brilliant and will help you understand what you are doing. Another great SubD modeller is Glen Southern he has lots of videos on YouTube using Silo 3D. More recently videos doing the same thing in VR using Occulus medium. Generally, the software does not matter. The concepts apply just as well to FormZ, Fusion 360 or a plethora of CAD applications that have implemented SubD.

    Rounding Question

    One way is an inside to outside approach. So start with triangle 1 draw a box over it and make it subD. offset the faces to give you some borders around the edges and your 4 sided triangles. Move the points around to get the form you want. The width of the subD borders should approximate the desired fillet radius. So the closer loops are the smaller the apparent fillet in subD.

    Rounding Question

    The main problem is edge-flow in your SubD model. Ideally, you should try to keep to a regular grid layout of your edges, so quad shapes rather than triangles. The depressions in the top should have an even boundary to the edges. With good edge-flow, you should not need to apply fillets as the interpolation between edges should accomplish that for you. Some reference for SubD modelling... Although the samples look like Blender this site should help a bit https://topologyguides.com/. Alternatively, one of the best references for subdivision modelling can be found here https://gumroad.com/vaughan3d?query=topology workbook&sort=page_layout $25 each but worth far more than that in the improvements you will see in your modelling. William Vaughan has tried to make the reference as software agnostic as possible but most of the examples werecreated in Modo. The ebooks are also a good reference if you use T-Splines in Autodesk's Fusion 360. Most Cad applications have now embraced subdivision modelling.

    insert opening feature not working in v9

    Thank you. The reason I try this way, is the openings calculate much faster than boolean subtraction. With so many holes (4929) it is a difficult boolean. This technique works well in 8.6 but seems to have issues in 9.04 etc. The issues are not always the same, even on the same geometry so, for now, a bit of a mystery. Picking is very easy. Set pick type to hole, then window select over the whole object. This is great for removing openings of simple move and rotation. I wish the clone feature would work with this to allow local scaling and rotation etc. Another way is to create a 2D opening and create an array, then use the imprint tool. Carefully picking the single face representing the surface and extruding works well in 8.6 (not tried in 9.04 yet)

    insert opening feature not working in v9

    Ah it can fail. Exactly the same process again only this time multi copy only copied some of the openings. So perhaps I am not going mad after all. ;)

    it seems not arrays. I meant multi copy sorry.

    insert opening feature not working in v9

    Sorry, it may have been something stuck in my scene. I just got it to work now but cannot see what might have been different. I cannot get it to fail now, even reopening the original scene. Visually it was just drawing 2D rectangles not cutting the geometry. Works now even with arrays.
  8. works fine in v8.6 doesn't work in v9.0.4 etc.
  9. Try triangulating the model. It is easier to help if you attach a screenshot of your export settings along with the file. One problem with FormZ that has always been present is that the file dialogues allow you to enter settings that don't work. This results in a file without geometry or other problems. If possible reset FormZ preferences and try again. The default settings for file export work for almost every situation. If you need to change something such as scale or orientation make sure you keep a reference to the default settings. Autodessys PLEASE add a reset to default option to the file dialogues. It would save users a lot of unnecessary grief.

    Clone & Unclone

    In theory, if you clone an object then edit it later, those changes will also be propagated to the clones. Clones are an option in the move, rotate, scale and mirror tools, and also now in the new array tools. Unfortunately, I have experienced nothing but problems with components and clones. If I want that functionality then I model items in formZ but use another software to reference them in a larger context.

    formZ help videos 404

    That's good to hear. Thank you

    formZ help videos 404

    I'm tripping over some nuances with the new symmetry tool but the help video link points to 404 page not found. I thought this may just be because it's not there yet for v9 but all the video links are broken 404. Is there an update or a way I can fix this?

    Lumion plugin

    TwinMotion now owned by Epic Games has a Mac version and whilst not as fully featured as Lumion is much cheaper. There are plugins for Rhino and SketchUp but OBJ and FBX work just fine from FormZ.

    from point cloud to terrain?

    Not sure if it is something Autodessys are likely to do. With the new Python scripting maybe a third party script but how long might that take? In the meantime, CloudCompare is free, has a Mac version and can accomplish exactly what you describe here. It does need a little time and effort to get going but it is more than worth the investment. For larger projects, I forgot to mention Global Mapper with its LiDAR module. It runs fine under VM Ware or Bootcamp but is quite expensive. If you already use Cinema4D Lazpoint is not expensive 240 euros. Paul Everett dropped the Mac version some time ago because there was so little interest. I do know he has Mac compiles for v1 because I still have it running on C4D R19. If you ask he will most likely sell you v1 or if you catch him in a good mood, even consider updating v2 for Mac OS.

    from point cloud to terrain?

    CloudCompare is free and manages this quite well. https://www.danielgm.net/cc/ Most of my point cloud projects start with CloudCompare. For architectural terrestrial scans (LiDAR) Pointfuse is good but arguably overpriced. https://pointfuse.com/pricing/ Sequoia is used a lot in VFX for meshing point clouds https://www.awsthinkbox.com/sequoia Agisoft Metashape can process point clouds as well as photogrammetry https://www.agisoft.com/ Cinema 4D users have the LazPoint plugin https://cinemaplugins.com/c4d-plugins/lazpoint/ (This is what I use, as I rarely need to create a mesh.) Usually, I just render the points or us the point cloud as modelling reference. Rhino has several plugins for handling point clouds and can import e57 and ASCII formats natively.
