Automatic (??) constraints

[Anonymous]

If I project, for example, "Center Point" and then create a line, with it's endpoint at that center point, the line is fully constrained. It turns black...

Why though if I point to the center point - but don't click - and then move away to get that dotted "implied" constraint, does it not automatically constrain also ??

I guess it's because it's a point and not a line that you're implying the
contraint to. It shouldn't really be displaying the dotted line in this
case though.

Just had another play and the dotted line is not the implyed constraint it's
just for initially sketching things "lined up". The implyed contraint just
"magnetically" snaps the cursor it doesn't draw any sort of line.

I might not have made it clear, but I do "use" this implied constraint. Let me show some examples....

This screenshot shows a line with it's endpoint at the Center Point. Obviously it's contrained (black in color). Second screenshot in next post.

Showing implied contraint.....

Using the implied constraint, I created this line. It ends up not constrained though (and I'd like it to). I realize I can Fix it...

The dashed line does not add a constraint...this is how the sketcher has
worked for many releases. BTW, your "black" line isn't "fully" constrained
until you add a dimension to it...I like to think of the color change as an
indicator that the position has been defined but not necessarily the
size/length. Just my $0.02 (which isn't worth much, I know).

I'm not worried about the length.... So long as it's constrained to the center point location, I'm happy.

Hall,

Inferred constraints don't create actual sketch constraints. In your example
you are inferring a coincident constraint with the projected point. While
the line appears to be coincident with the point no constraint was actually
made. You can still drag the line off the point, hence the line has the
underconstained color. Just apply the constraint or draw the line without
inferring the constraint.

I hope this helps,

Yes, I understand that and it's also my complaint (or request). An option like "Allow inferred constraints to be sketch constraints"... Make it off by default.

[Anonymous]

I'll log the wish.

Thanks,

Shouldn't be to hard to do...it already does this in the drawing environment
when sketching section views!
