Fully Constrained Issues

jdpreynolds — Tue, 22 Nov 2022 05:33:52 GMT

Hello

I am trying to correct some issues with my drawing that are causing "downstream" problems with getting sketches to be fully defined. I see that the "Hub" sketch is not fully defined even though the drawing is all black and reading through the forums see that this is an issue that others have had also.

I am trying to work out what I have missed to get this sketch "fully Defined" any help will be much appreciated.

Thanks

Julian

Use the Text Command, Sketch.ShowUnderConstrained, to find unconstrained geometry.

p.s. The first Sketch.ShowUnderConstrained with 3 points was from a different file.

That's really great thank you

If you keep the 7 small fillets out of the sketch you'd be surprised how quickly you will create stable fully defined sketches without problems. Keeping edges sharp as long as possible and applying them at the end of the timeline will also likely make lofting the spokes easier.

Hi Ed/Peter

wonder if you could help me one more time,

I have gone through my sketches and now have them fully defined and just redoing the sketch "Spoke Profile 3/4" For some reason I can't get the two circles to (R7/16 & R9/16) to turn black, I have applied the coincident constraint to the vertical construction line and to the upper and lower "Vertical guide rails" and applied the Radius dimension. Can you see what I have missed out?

Many thanks

Julian

Click drag the circle, likely will slide up and down. Hide the rails, and Coincident constrain the circle to the centre line end point.

Might help....

Hi,

What you need are the intersections with sketch "Vertical Guidelines", but not the projection of its 3D contour.

1. How it works:

2. quick coincident
