parallelepiped, what am I doing wrong? (by danix)
Hello everyone,
sorry if this question has been posted already but I haven't found anything while searching, I'm learning my way around solvespace and as you can see in the file I've attached, I'm trying to build a parallelepiped, but I haven't managed to get it to work, what would be the ideal workflow? In this attempt I've tried to extrude a 2d square, then I've drawn triangles on the 4 profiles and extruded them as well, but of course the corners are empty.
Could you please point me in the right direction?
Thanks a lot in advance, I hope this is the right place where to ask this kins of questions.

I guess you want a skewed parallelepiped, since a right parallelepiped is easy (just draw the parallelogram and extrude)? I don't know an easy way, but I'd probably start with the right parallelepiped and carve pieces off, seems easier than adding back on.
Or maybe sketch in 3d, and draw the wireframe first? I don't think you can make a solid from the wireframe, but then at least you'd have the guides for your extrusions.

Draw the larger rectangle,and use triangle to remove the unwanted material. It pays to draw and extrude each triangle separately, as doing both side together as a single extrude cause nurbs problems.

thanks for your help, what I'm trying to achieve, is a figure with a bottom square and a top square but smaller, kind of what you can do with lofting, but I've seen that it's not yet implemented in solvespace, so I'm looking for an alternative approach.
if i draw the side profile in 2d and then extrude, I'll have 2 of the profiles flat, but i want to have the same angle on all 4 sides, i don't know if I'm explaining myself very well.
thanks again for your replies..

Like a square pyramid with the top cut off? That's not a parallelepiped (since the faces are trapezoids), but I'd use the same "cutting" approach, draw the cube and then extrude as difference four times to make the four slanted sides.

How to extrude at an angle (skewed) is described here:
