when you set the tool options : Resolution to Scheme : Default Minimal it works. vva

hi Ged, when opening your file I see more than 50 identical objects. They were on the locked layer "Jackpot furniture" . When you delete 53 of the 54 objects you will find the object ca. 4000m away from 0,0,0 . you can copy it, but use "Object Doctor" first, because it has 118 non planar faces - or - much better - rebuilt it in formZ. (I suppose it was imported form SU ??) vva

here is the file: Grid 40mm.fmz.zip

you have to reduce the over all grid size and zoom in to see the grid

Thank you for investigating this! in the meantime I found an Exel doc with a good graph that I used as underlay and made the curve as nurbs. so I got this: vva

hi Chris, this is the formula I used - the exponent as a decimal number: 2/2.5 = 0.8 (Piet Hein used 5/2) and I made some experiments with a variable (v) for the exponent: thank you for your help vva

I tried to create a "Superellipse" with the tool "Curve by Formular" . (have a look at > Wiki > Superellipse) didn't get it to work - but produced a lot of crashes any help is wellcome vva

hi Chris why do you prefer to built it with faces ? when Craig wants to make 3-D prints, he needs volumes. vva

hello Tom, the best way to import sketchUp files , is never try to do it. the geometry is horrible and the time to correct it is ten times longer than building new in formZ good luck vva

thank you very much for the help. I imported the contour of the face as a 2D .dxf file. that was an old file and therefore facetted vva

a very simple thing ? I try to change the radius of the 4 edges from R=1,0mm to R=2,0mm. but none of the tool works. (btw. 3 of the 4 sides are rounded with a big radius) vva R1toR2.fmz

perhaps this file can help: (it is about 8 years old) Frosted glass.fmz.zip

yes, holes are a bit problematic. in the last years I use the .stp export (3D) and most newer machines can work with that files. have a try vva

hi you can use the orthographic projection with the "Derive tool" (the last one in the Derive palette) -if your panels are flat. Or "Derive Segments" - with Shift select one after the other segment and copy to a new file. good luck vva

Hi all, to make clear that you can not saw a curved - non planar- face - even with a cnc cutting with a 5 axis circular saw you need a 5 axis milling machine... So my hint was to use the midpoint of the segments (best compromise) to get the angle of the mitre ! now you can use the angle for a numeric input to your machine or to construct the mitre of each edge. (in different ways, sheet by sheet and edge by edge) And as Des said. "The outer boundary face edges would still not perfectly line up so would have to be planed after assembly." vva
