    Curve by formula

    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

    Curve by formula

    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

    Curve by formula

    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
  5. 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

    Rounding a face

    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

    Rounding a face

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

    Export for CNC paths

    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

    Export for CNC paths

    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
  11. 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
  12. Hi you have to align to midpoint of segment ! so it may look like this: vva
  13. hi Gyro, I hope I understand you right: >"The problem I’m having is finding the angle where the facets meet."< I do it this way: draw a rectangle (100x100mm) and use the "Place On" tool. Use "Segment Midpoint" and "Along Normal/Tangent". select the rectangle and then the object. Now you can measure the angle for the Now you can measure the angel on each side of a face for your cutting machine. vva

    Simple modeling... stuck on basics!

    In FormZ, this takes about 15 seconds, in this way: 1) Create wall 2) Drag vertical guide in 2" from left > use "Offset a Segment" ! 3) Drag vertical guide in 2" from right > use "Offset a Segment" ! 4) Drag horizontal guide up from bottom 3' > use "Offset a Segment" ! you don't need > 5) Create rectangle on surface, at 16" x 9", at intersection of left & bottom guides you don't need > 6) Select rectangle and scale proportionally from top right corner to right guide 7) Push 1" with the "Transform Tool" good luck vva
  15. another way to check: draw the (3D) diagonale through the cube, group with the cube and rotate like Setz told you. now you can check the diagonale standing exactly vertical. vva
