allow primitive Cylinder and Cube to grow All directions !

[cekuhnen]

With a cylinder primitive I can only extrude into one direction - that is limiting when for example you need symmetry.

With a sketch as a start and then extruding it I can extrude into both directions.

 

So ideally the primitive should grow into both directions.

Currently I would need to extrude the other side by as much as I defined the length of the cylinder

adding an additional modeling feature to the timeline.

In this case, we recommend users to start with sketch instead of primitives. We currently have no plans to improve primitives and are focusing on higher priority projects.

@keqingsong This goes back to the sketch free working thread and the issues that were discussed there.
