Tangency Issue Between Sketch Vs Modeling

[Jashe]

I am having a hard time getting the curves of this model to look tangent. I put tangency constraints in the sketch. I've attached a screen shot. Has anybody else had this problem (I'm sure)?

It could be just a display issue, but it's hard to tell from here.
So, it could actually be tangent when it doesn't look tangent.

How do you know it isn't tangent ?
There is a Surface continuity analysis function, try the "multi faces" option.

I adjusted the Visualization-Faceting tool and it does look better. I've attached a screen shot. As far as the Surface Continuity, I'm going to need to research on how to use that tool before I can understand it.

In the examine geometry dialog "no results" does NOT mean that the checks passed; rather it means that those checks were not run because there was no geometry of that type selected. Rectangle select around the entire model to pick up the body, faces, edges, and other desired geometry (such as curves).

The easiest and fastest way, although it's technically not 100% accurate, is to change your Visualization settings such that Smooth Edges are displayed with a different line font. I prefer Phantom lines. On occasion, you will run across a few instances where this won't be accurate but more often than not, and especially with G1 (tangent continuity) you'll see the line font change when the faces are tangent. If you do this, make sure you select ALL views or when you use Replace View it won't apply it like you would want. The only time this would not be recommended is if your Modeling Angular tolerance is set extremely low compared to the visualization tolerances used to determine a smooth edge.

It's difficult to tell what you're describing because you've shown 2 completely different parts - one includes recesses/cut outs that look like they're not tangent and the other shows a cut section through a completely different solid body.

Thank you all. I got some good info from all of you.
