Hi Michael,

World x,y,z axis in 3d view.

Hi Michael,

Thinking about it, 3D view-based rotation as you described could also be interesting to quickly adjust object rotation.

But this would be for a different usage than for making plan details.
Adjusting profiles along a sweep object of organic shapes could be a usage example.

Maybe this manner could work without the rotation angle 90º constraint or have a modifier to snap to.
The command could trigger rotate, center, and mouse "up or down" or "left and right" could approximate the rotation angle.

Thanks,

Marc

Hi Marc, ok try the attached script.

Instructions for installing a plug-in script command here.

Set one of these for the command on each arrow key shortcut, note there should be a space after "Rotate90RelativeToView" :

Rotate90RelativeToView Left
Rotate90RelativeToView Right
Rotate90RelativeToView Up
Rotate90RelativeToView Down

Hi Michael,

Works like a charm, you are a magician !

Thanks for taking the time to look at this.

Here's a project I'm working on, a Morris chair design with assorted table and leg rests in cherry wood .
The command will help in the laying out of individual parts.

The spacebar script to switch view is fast also...especially on a laptop.
cannot live without it.

---

Indeed !

Is it the script that toggles the active viewport to fullscreen, and goes back to split view if pressed again ?

Marc

---

Yes..thats the one. ctrl+spacebar will flip left to right, front to back etc.

Hi Matadem,

I didn't know about flipping the view 180º, quite interesting.

Thanks !

Marc

Ctrl+space script:moi.ui.mainWindow.viewpanel.reverseView( moi.ui.getActiveViewport().name );

This is the way I have it setup.

Thanks !

Hello Michael,

I've noticed that if I set arrow key Up with command Rotate90RelativeToView Up, so the model turn Down and vice versa, if I set arrow key Down with command Rotate90RelativeToView Down, so the model turn Up,

therefore I changed the order of code from:

case 'left': view_dir = frame.yaxis; view_dir.scale( -1.0 ); break;
case 'right': view_dir = frame.yaxis; break;
case 'up': view_dir = frame.xaxis; break;
case 'down': view_dir = frame.xaxis; view_dir.scale( -1.0 ); break;

to

case 'left': view_dir = frame.yaxis; view_dir.scale( -1.0 ); break;
case 'right': view_dir = frame.yaxis; break;
case 'up': view_dir = frame.xaxis; view_dir.scale( -1.0 ); break;
case 'down': view_dir = frame.xaxis; break;

now the model rotation correspond to arrow key dirrection.

Is that right?

Thanks

Mik

Hi Mik, yes you're correct, thanks for the bug fix. I have updated the script above.
