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

Hi you have to align to midpoint of segment ! so it may look like this: vva

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

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

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

hi Rudy, I have no problems with your file, but used “ObjectDoctor“ before exporting. OBJ-Crash_Object.obj

the easiest way to solve this is to use "Derive > Projection" to ground plain. vva

In the "Open" and "Import" dialog the checkbox for "Add to project" is not available. click on the "Options" button shows no reaction... vva

hi JL, there are 3 small holes in your hood (for the cables), they make the faceting a bit complex. work around : derive the contour and rotate it. so you have best control over the faceting. vva

yes, it runs fine. no problems here...

good morning Jean Luc here is the zipped file : https://www.dropbox.com/s/mwukfgcjnovidy3/SKYLOOP.IGS.fmz.zip?dl=0 there was a lot of corrupt geometry in the file it worked with skip point and text objects and "heal corrupt geometry" vva

Allan please try this file: Measure between.fmz.zip vva

Allan, I think your objects have some problems. I did the following: derive the top faces of the objects, use Object Doctor and give them the height again with the Reshape tool. i'm on iMac 10.13.5; fZ 8.6.2 (10099) vva

hi Allan, the distance from top to top is 2,00m but the "Measure Between" tool measures from top to bottom and because the thickness of the upper object is 0,10m you get 1,90m between the objects. vva

the left part of the tubes has severe problems. delete that object and rotate with copy the other object and then you can union both objects vva
