Re: line between two planes

Hello,
thanks a lot for your answer I am uploading my file. I have an additive helix that I would like to connect with sk05 and sk07. I imagine that I need a line between sk05 and the beginning of the helix to do a sweep. Best,

line between two planes

Hello FreeCaders, Happy New Year and humble apologies if this is a really dumb question. I have two sketches on two planes and I would like to join their centers with a curve perpendicular to both planes to be used to sweep one sketch into the other. I do not seem to find a way to do this. Thanks in...

Re: Terminally confused in using GDML

Thanks for your interest in my problem. Actually, I tried all meshsers (standard, Mephisto, netgen, and gmsh) and I could not get very good results. Meshing is irregular and more or less crude. The best results are with the standard mesher and then decimation with Blender. Actually, Blender is reall...

Re: Terminally confused in using GDML

Thanks! I have found your file. I do not know how to load "by default" the Geant4 materials, but I can load them, find all the NIST stuff, and so on. Brilliant. Spurred by your explication, I have found the following: - Meshed the object in the Mesh workbench. - Exported as .stl - Imported...

Re: Terminally confused in using GDML

Yay! I love this forum where people answer so quickly and so thoroughly! Thanks a lot! A couple of points here. I managed to know whether it is possible to control the tessellation parameters since it looks a bit uneven and produces *a lot* of volumes. I checked the file you sent me and mine, and th...

Very nice, however, it does not follow the Bezier curve (that sticks out). But if you make it follow the curve, it still works (and the size of the file explodes!). See attached drawing. Thanks a lot!. Best,

Thanks a lot. What I was trying to do is to use a 3D line. Since a sketch is always bound to a plane, I tried to use a bezier that can be bent in 3D. Best,
