How to prevent sketches from ever snapping to origin?

[dewaine50]

Normally when you try to snap to a circle center, there's a circular indicator for you to start your line.

However, if that circle just so happens to be on the origin, the line will snap to the origin at the red and green dots, even if you have everything turned off. How do I force it to snap to not ever snap to origin?

Hold down the Control Key.

Don't draw it near/ on the origin.

But snapping something to the Origin is usually required for stability.

No, what I really want to do is center it against the center of the circle, not the global origin (Really useful for when say, the object will move .005mm in any given direction). I want a consistent way to reference. Other circles can reference constraint on their centers, a circle near the origin should follow the same rules. Yet every time I mouse near the center, it'll show a green square constraint (indicating global origin, which is wrong) instead of a green circle (indicating the object's origin). I need a way to remove snapping against origins.

Catch 22, those other circles are not on the Origin, and Fusion will give priority to the Origin.

You can - delete the coincident constraint for the correct circle.

Draw it anywhere in space, then use dimensions relative to the circle to position it.

If your eyesight is good you can see either the circle snap or the Origin snap in the screencast depending on which is closer to the cursor. The circle is .0001" in X and Y away from the Origin.  Zooming in will of course make it easier to select which one you want.

Hi,
Zoom it and place the first point of your line.

Thank you

The circle won't always be at a convenient offset; sometimes they're exactly on the same point and you need a clean discriminator between selecting circle center vs origin so that you don't select the origin by accident.

And of course there are times where you can't tell if they're offset by .001 or are exactly eclipsed, hence a CLEAN guarantee of selecting just the circle center is necessary.

I need a consistent way to NOT select the origin every time. That way I can guarantee I am in fact selecting the circle center and not make a mistake when the part goes to parametric changes. Is there just no way to invisify the green-red axes/origin altogether?

Concentric Constraint?

[etfrench · Accepted solution]

When you're using the concentric tool, the target will be "bolded".  It's quit easy to tell if you're making a line endpoint concentric with a circle's centerpoint or the origin when the circle's centerpoint and the origin are concentric.
