Thanks Frank ... very much appreciated ,-) It is good to know, that there are that you did not critique ... these are the same I am going to improve
@Piet and anybody interested:
A simple workflow - images form top-left to bottom-right - in every image the Z-axis is showing to you, X to the right, Y to the left (with a little rotation) - world center is almost in the middle of any image:
01. Placing a Hyperrod Barrel at the world's center
02. Placing a Cylinder at world's center and scaling it a bit
03. Adjusting the Cap depth and Neck radius of the Hyperrod
04. Moving both along the X-axis off center
05. Duplicate and mirror objects
06. Adding a Hyperrod Barrel at the world's center
07. Turning this Hyperrod, scaling it, adjusting Neck radius and Cap depth
08. Rotated all 90° around the Z-axis, adjusted length of the cylinders, moved the red armatures along the X-axis off center and did a Duplicate and mirror of the red objects
09. Duplicated the middle Hyperrod and rotated it, adjusting size
10. Rotated everything 90° around Y-axis, moved the objects along the X-axis off center. Duplicated and mirrored those red ducts
11. Selected the two, small Hyperrods, which are facing each other. Used 'Selection Center' to add a cylinder. Rotated and scaled it.
12. Added a few gimmicks and rendered within Groboto.
I hope that this helps a bit ,-) Else, I can only advice you to watch the videos about modeling. The Snap-functions are really handy. And it is good to know, how to rotate objects around each other ...
Regards,
Volker
Edit: The bug mentioned a few posts before has just been fixed with a new release ... ,-)
