Model in “Perspective”…Print to scale in “Parallel”.
Use cardinal axes to rotate Triangle Group to intersection of “Arc” with Vertical height.
Zoom is your friend.
Use a single Triangle Group in radial array.
Get the “faces” right…
A few “flaws” in my technique for sure!
Solid Inspector2 not happy with “Nested Instances”…Explode Curve corrects this? If so, Happy Camper.
Yes, the way I was trying it context-click showed “Explode Curve”. After hours of fiddling and tweaking I finally “fixed” my errors…Thought this CAN’T be right and asked for help. Your “Edits” were very enlightening!
Sorry for taking up more time…just wanted to say thank-you.
Alas…Works fine for “regular triangles” (3 equal sides) but if triangle “scaled” to equilateral (2 equal sides with original base) the problem persists at the point of intersection but not rotation. Will start new topic with “Accurately Rotate Scaled Triangle from Regular Polygon Issue”
BTW, it’s possible to create a tetrahedron without swinging an arc and hinging a face … but, if you want one face flat on the ground, you’ll still have to use the rotate tool to rotate the whole object over. See this post here:
