I'm struggling with a design, and I wonder if I'm not understanding how I'm supposed to design something like this. I'll try to illustrate, here's an incomplete version of a design:
So, I have a fairly simple base shape that is almost an isosceles trapezoid, extruded to a fairly thin solid. The longer parallel edge is furthest away, the shortest parallel edge is nearest us.
On the far side there's a "tube" or tunnel, which is basically for a hinge. On the near, slimmer end of the base shape, I want 4 or 5 "tubes" - but with some additional details. There's an additional copy of these parts to the right in the screenshot. They are pointing towards us but their rotation should be evenly distributed from left to right. The ones along the edges are parallel to the edges, but the ones in the middle won't be. I guess they should roughly be pointing towards the same point in the distance, but I'm really not that concerned about this. An approximation is fine.
How would you go about designing this? I think I'm simply doing this wrong.
I figured I'd use the assembly2 workbench a try for this, so I designed some basic shapes and proceeded to assemble them as I needed. I gave up assembly2 just before chewing my screen with frustration. I moved on to a2plus, and I've managed the hinge at the back, and the two along the sides. I'm not sure how to place the 2-3 final tubes between these, with the rotation. And even if it's possible using assembly2/a2plus - what is the "correct way" of drawing something like this in FreeCAD?
I've included the freecad files of the basic shapes. They were made in FreeCAD 0.17 from the stable ppa, I'm currently running a FreeCAD 0.18 AppImage downloaded today. I installed a2plus using the addon manager. I was using an older version of assembly2, and after I tried upgrading it started crashing immediately when I added any part to an assembly. I'm on Ubuntu 18.04.
