What is the best way to get a box to sit on top of a cylinder.
Here's one way: First, move the Reference Point of the box to whatever part of it you want to be in contact with the cylinder. I'm not clear what "on top" means here, but it looks like you want the box to be tangent to the curved face of the cylinder. If this is the case, click the "Selector 3D Properties" icon on the Inspector Bar and set both Extents CS
and Coordinate system
to "User CS." Then select the cylinder and click the "Set UCS by Selector" button on the Inspector Bar. This resets the reported Pos
values of the cylinder to zero. Finally, select the box and change its Pos
values as required, being aware that these values will be using the center of the cylinder as the reference -- which means that one of the Pos
values should be equal to the radius of the cylinder.
Also, what would you do to show a weld? My idea is to make a triangle and extrude, any better Ideas?
Extruding a triangle is a reasonable approach. Or use a more realistic cross section if you want greater realism. Alternatively, Boolean-Add the parts to be welded and Chamfer or Fillet the joint.
The attached illustration shows a weldment created in TCad using a "more realistic cross section" and making extensive use of wrapped images for "Textures" and "Patterns."
