TLDR: Do you fully constrain sketch CONSTRUCTION GEOMETRY?
Readers version:
When using CONSTRUCTION GEOMETRY in a sketch I always make THE CONSTRUCTION GEOMETRY fully constrained with dimensions and other constraint types so that my sketch remains fully constrained because:
- Otherwise it's difficult to tell whether some critical geometry is fully defined.
- I like things to be fully defined without any DoF.
It occurred to me that I don't know if this is good practice or not. Does it add unnecessary calculations for the CAD software and slow things down or does it help by fully defining THE CONSTRUCTION GEOMETRY as well as the other sketch geometry?
Note: I always fully define the rest of the geometry, this is a question about CONSTRUCTION GEOMETRY, which might for example need centre point and angle defining but not NEED a length to achieve its purpose.
I'd appreciate other's opinions on whether the additional step of CONSTRAINING CONSTRUCTION GEOMETRY is necessary.
e.g. this
vs this....
[edit]
I deleted the original sketch images and modified the question to remove context because all the answers related to how to simplify the sketch, rather than whether people fully constrain the construction geometry.
See post later on with an example.
I'll update this in the future when I next find an example with a good screenshot.
