Free Sketching

[carlharr]

Hello,

We have a user who is attempting to draw a "free sketch" to replicate a bitmap background image (using sketch in drafting).

When he clicks to position one end point of a line, then moves the mouse around, the line seems to rotate in 1 degree increments, rather than freely in space.
This is not constraint snap angle, for inferred constraints (which can be turned off) - its more like a "grid snap angle".

Is there a way to turn this off?

Thanks Carl

Yes and no, press the ALT-key and it is temporarily disabled. I don't know if one can turn it off permanently.

Regards,
Tomas

Hi Tomas,

This isn't the inferred constraints snap angle, its more like a 1 degree snap as you rotate a line around in space (in a sketch).
You can see the effect if you create a sketch in a blank part, start a line at the datum point, and then rotate the line around in space.
It always snaps to the nearest 1 deg angle - its this snap we need to turn off?

Hope that makes sense!

Thanks, Carl

I am almost certain that is associated to the snap angle.

Hi Jerry,

That was the second thing I tried, but it has no effect (even if you adjust it right down).
Snap angle is used for "snapping to constraints" with other sketch lines etc. which is not a problem (can just turn that off with ALT).

This model is a sketch with only one line in it, with nothing else in the model at all (except the datum CSYS).
With one end placed, you can rotate the other end and will see it snaps in 1 deg increments.

Hopefully Im making sense here?

Cheers, Carl

Is the grid turned on?

It's NOT associated with the 'Snap Angle' nor whether 'Snap to Grid' is enabled. It's just a characteristic of the fact that the displayed value of the Angle is in whole integers. It's not that you can't type in a floating-point (i.e. decimal) value just that until you do so the software has to use some sort of convention to determine what value to display (and honor) when tracking something being dragged on the screen.

John,

Thank you for the explanation, that makes sense. I will send it on to our user!

Cheers,

Oops, I'm wrong here, Normally the ALT key temporarily disables this type of interaction , but not here.
