To me it looks it's made with a polygon modeler and ready to be subdivided, according to the text. So it's an subdivision surface model. Afaik you need a polygon model of your model and then subdivide it with Max's subd script. I bet also you need to experiment a bit in a polygon modeler to get those roundings right in the cells.
Hi Daiber, that's going to be a pretty difficult style of model to create in a CAD program like MoI which is overall more focused on generating stuff from curves.
Polygon modeling tends to be better for more organic type shapes that have a melted like structure to them - those are programs like Cinema4D, Modo, Silo, etc... - they use a different style of 3D model construction than what MoI is focused on.
It probably would not work very well to try and build it in MoI - it would be possible to build a sort of curvy individual cell by creating several outlines and moving them in Z from each other and then using Construct > Loft, but it will be difficult for those cells to then be blended with each other where they connect up.
Polygon modeling programs use a technique called "Subdivision smoothing" which basically melts and smooths the initial cage all over, it tends to work better for the type of thing that you're asking about here and it is very likely that the original model that you're trying to duplicate was done using polygon modeling and not with a CAD program.
So you have your round VoronoI forms diverted
Put a plane with any form you want around the VoronoI forms
Boolean DIff = you have a plane with holes
Select holes
Extrude them with Taper option (or make a Revolve with a curve if you want curvated walls )
Boolean Union with Plane (erase tops)
Fillet if needing
That all! :)
Hi Pilou, what you show there works but it's kind of a different design than the original one, you've left more space around each cell and you have more of a flat area between them. The part that's difficult about the original one is having not much space between the cells and having the cells kind of melt into one another rather than being separated.
If you modify your example by moving the cells close to each other such that there isn't enough room for a fillet to fit, then you'll have a lot of difficulty.
Yes it was just a concept :)
But seems there is no fillet on the original ? - So I can approach the forms between them and don't make fillet! :)
The more difficult will be make revolve by Rail on each hole one by one :)
a possible way is to create the voronoi diagram with Max's script. Create a underlying plane and split it with the diagram. Then make a tappered loft with the plane fragments. Make a extrude with the outline of the diagram. Substract the frustrums from the box and delete the sidewalls and the bottom. Make a subdiv with Max's script. If you play with a second frustrum level maybe you get an equal result.
And another try:-)
Voronoi -> Split base plane -> select naked edges -> copy - paste -join - delCorners - explodemove (thanks Pilou:-))- extrude tapered with negative angle - select solids - union - substract from a cube | 5min fun!!! Then try to blend/fillet erverthing -> a nightmare - not only in Moi3D;-)
in the first picture upper right, there is a line that seem shorter than 5mm - typically that makes an fillet impossible. The fillet operation has to left a segment of the input lines - that may cause the problem.
Hi GonzoRus, re: filleting failing - like Karsten mentions above it's probably because of the large fillet radius that you were trying to use there. In many areas it looks like you don't have enough space for a radius=5 arc to fit. The fillet will fail if you have that situation.
You would need to try a lower radius value for Fillet to have a chance there.
If you need more help or information about the areas where radius=5 does not fit, please post the 3DM model file with your curves in it so others can take a look at your actual model instead of only a screenshot.
Try using much smaller radius values like 0.1 , 0.2, 0.5, or 1.0 to see if those succeed ok or not, that's what I would be trying if you had posted the 3DM file. Or for a larger radius you might be able to make it work if you only select areas where there is space rather than trying to do the whole thing.
