How can I scale multiple objects from each objects center?

And here is a script that will do this. Copy the the lines from Procedure to Run and paste them into a new VectorScript Editor window.

{==============================}

Procedure ScaleEachObject;

{Scales each selected object in the active layer around the obejct center}

Var H1,H2:Handle;

N1,N2:Integer;

A1:Dynarray[ ] of handle;

R1:Real;

Begin

N1:=Count(Sel);

If N1>0 then

Begin

Allocate A1[1..N1];

N2:=1;

While N2<=N1 do

Begin

A1[N2]:=FSActLayer;

SetDSelect(FSActLayer);

N2:=N2+1;

End;

R1:=RealDialog('Enter the amount to scale each object by','2.0');

N2:=1;

While N2<=N1 do

Begin

SetSelect(A1[N2]);

Scale(R1,R1);

DSelectAll;

N2:=N2+1;

End;

End

else AlrtDialog('At least one object must be selected');

End;

Run(ScaleEachObject);

Pat, this looks useful. How about adding it to the new sharing forums so that it doesn't get lost.

This might be a useful compromise rather than relinquishing copyright for your hard work when sharing resources.

Here is a revised version that fixes a bug I either missed or that was introduced in a later version of VW. Tested on VW2011.

The bug was when only groups were selected the script would incorrectly say not objects were selected and set stuck at the error message.

Procedure ScaleEachObject;
{Scales each selected object in the active layer around the obejct center}
{? 2007, 2010, Coviana, Inc - Pat Stanford pat@coviana.com}
{Licensed unde the GNU Lesser General Public License}

Var	H1,H2:Handle;
N1,N2:Integer;
A1:Dynarray[ ] of handle;
R1:Real;
Begin
N1:=Count(Sel);
If N1>0 then
Begin
	Allocate A1[1..N1];
	N2:=1;
	While N2<=N1 do
		Begin
			A1[N2]:=FSActLayer;
			SetDSelect(FSActLayer);
			N2:=N2+1;
		End;

	R1:=RealDialog('Enter the amount to scale each object by','2.0');

	N2:=1;
	While N2<=N1 do
		Begin
			SetSelect(A1[N2]);
			Scale(R1,R1);
			DSelectAll;
			N2:=N2+1;
		End;
End
else 
Begin
	N1:=0;
	AlrtDialog('At least one object must be selected');
End;
End;

Run(ScaleEachObject);

Thanks for your replies - I'm still having problems with the script.

I can now seem to get it to scale, but only after a huge number of error boxes of 'no objects selected'. I've recorded a short video showing my process, perhaps I'm going wrong somewhere?

If anyone has any advice I'd be greatful as its a very useful tool!

Here's my attempt using Python. (attached txt file version of script)

My vectorscript is very rusty.

This can be fixed by replacing line:

N1:=Count(Sel);

With an option to select only the visible selections 

 

N1:=Count((VSEL=TRUE));

I've just been trying to use this to scale multiple 3d objects.

Realised that it uses the 2d scale command, which is why it didn't work.

 

I tried replacing the vs.Hscale2D in line 29 with vs.HSacle3D ... adding a 3rd center[] and a 3rd scaleAmount in the hope that might work - but no luck.

 

Completely out of my depth trying to work out why!

Swapped out the HScale2D for HScale3D, and seems to scaling fine here. Working on Extrudes though. What particular 3D objects where you trying to scale?

Thanks for that. I tried it on a bunch of extrudes. It did scale them all, but it didn't seem to scale relative to each object's centre. Here is the before & after (lines on the ground are for reference and weren't scaled):
