[Request] Rotate Constrained

Rich O Brien

In SU when you rotate a selection thus...

...it narrows/widens the dimension

Is there a tool tht prevent this so the dimension is constrained on rotation...

I know I can place a series of guide and shift geometry around afterwards.

Or I am having a Doh! moment....

Hi, Rich:
The only way I know, is to rotate copy and correct the geometry. Do you mean a script? Perhaps Didier Bur's Projections?

pilou

Seems there is the FredoScale for that
I come back in 5 minutes for the video by himself!

from this thead of anthology

Second video ...But maybe i don't understand the question

Box

You are right Pilou, you haven't understood the question.

Dave R

So just using Move on the endpoint/corner wouldn't work for you?

Rich O Brien

@Dave

No, I posted a simple example for illustration. I'm dealing with substantially more geometry

Dave R

I see.

pilou

All that is very cryptic!

Example? The simple example you posted wouldn't be too hard - but it'd be difficult to make it scale. How is the real life scenario like?

...I think having pivot point in SU would be very beneficial.

I suppose in this example I am looking for linear falloff extrude

Not one step, but relatively fast:

draw face
use EEbyVtO (Extrude Edge by Vector to Object) from TIGs Extrusion Tools

tt_su

In that case you want to apply a restraint on all the vertical edges to keep their directions. That would be doable. But I think you'd have to create a custom tool as this would be difficult to do with observers intercepting the native tools.

AAAh, now I See! Vicious problem!

for me with Fredo's taper tool it's a one step.

pilou

Excellent!

The trick was to take the entiere object!

"Pourquoi faire simple quand on peut faire compliqué!"
"Why make it simple when it can be complicated!"

Same remark than above: you must draw first something for the "Hot Point" with the protractor!
Because the Taper Tool has a distance and not an angle!
Normally a simple Help Line with the protractor is sufficient!

Morality : a rotation with constraint is just a tapering tapered taper!

pilou

Not so vicious!
Fredo Scale again!
Tapering of the bounding box seems make the trick ! So the Doh Duh for Rich!

& CleanUp by Thomthom at the end!

10 seconds with a hand attached in the back
Of course you must make an Helper guide line of the angle wished first by the external Top edge!
So 2 seconds more!
