Rotating objects toward a body in line with center

I’m trying to build a component of a hydroponic vertical tower garden. There is a main center body vertical tube that will have three smaller tubes protruding from it at 45-degree angles. But they are spaced around the center tube evenly at 120-degree angles from each other. I planned to extrude all of these upward, then rotate the smaller tubes into the larger tube at 45-degree angles, then adjust the positioning, and then use shell. I’ve created a sketch of the larger center circle, and three smaller circles. After extruding these I tried rotating the smaller tubes. The one along the x-axis rotated toward the center as desired, but the other two rotated in parallel with the x-axis also. Is it possible to force all the smaller bodies to rotate in line with the center of the main tube, which is also the origin point? I might not be asking the right question, or maybe I’m going about the whole process wrong. I’m really new at 3D design in general, and with Shapr3d. Thanks.


In your sketch, draw lines between the center point of the central circle and the center of each peripheral circle. After you’ve extruded the cylinders, for each peripheral cylinder, select the Move/Rotate tool and move the gadget to the center of the cylinder, which should align it with the line you just drew. Then simply select and rotate the cylinder along that axis. Union the four bodies and shell it out, Here’s what mine looked like.

Thank you! That was exactly what I needed. I really appreciate your help.

In S3D, you can achieve your goal with many different solutions. In some cases, continuous development of the drawing makes construction easier, so you don’t have to make difficult adjustments later. In this case, the “history” can also be used better.
