Want your opinion on Sketching - a debate
(OP)
Sketcher is a critical tool for modeling - perhaps the most important.
But when the first feature in your model is going to be a primitive (i.e. block, cylinder, etc.) do you actually sketch the block or sketch the cylinder?
Primitives should NEVER be used for anything other than the initial feature, but is it worth sketching, constraining, and then extruding/rotating a feature, when it is already available as a base feature in NX ?
We are debating this at my company.
Want to see what most people think...
For instance:
To make a “Square Head” pipe plug, you can make it two ways:
With 2 features:
Cylinder (0)
Rectangular Pad (1)
With 4 features:
Sketch (0)
Revolve (1)
Sketch (2)
Extrude (3)

Why do something with 4 features that you can do in 2?

But then they caught me by surprise when I tried to demo why they shouldn't be used as a second feature, and they worked fine because they've been improved!
No problem with primitives as first feature at all.

I also prefer the flexibility of the base sketch, for instance I can always go back and re-visit it to add in extra detail that would save me cuts, rounds or other features further down the line.

I have gotten into the habit of only starting with one primative though where a more complex feature isn't required.
