View Full Version : Math sucks, how about absolute measurements?

Is there a way to scale an already existing object to absolute dimensions rather than percentages? Say I have an object that was modeled at 59 inches but now I need it to be 48 inches. Instead of using scale and figuring out what percentage that would be, is there a way to say I now want this object 48 inches tall and 29 inches wide?

Two ways.

You can either let LW do the maths for you , i.e. type 100/59*48 into the scale factor input field.

Or there is a plug-in that can be found on flay.com that does exactly what you want. Can't think of it's name (LW's on my other computer), but typing "scale" into Flay's search engine should find it easy enough.

Lw has a plugin for that, it's called "absolute size".

You can find many better implementation of the same tool on Flay, one of them is "Dimension +".

Pictrix Resize is vastly superior- numeric input, snapping, stretching.

All in real time.

and free...

Thanks guys. I downloaded Dimension+ and it seems to do what I need.

Oh come on. If u had an object say 28 x 36 and u want it to be 20 x 28, that's easy! that is a .7143 reduction in size. Now just multiply it by 100 (for 100 percent since that's what lightwaves looking for) to get a 71.43 percent reduction! How'd I get it? 20 (size we want) / 28 (size we are) = .71428 * 100....

Just remember, to reduce the size of an object u need to be smaller then 100. to enlarg an object u need to be larger then 100!

So to go from 20 x 28 to 28 x 36 we'd scale it too 140! Simple, no plugs needed besides Lightwaves Size (+H)!

My "math sucks" comment was more of a joke than anything else. I didn't say math was necessarilly hard, just annoying. Especially when you start getting into scaling that isn't constrained proportionally and also trying to figure out the exact dimensions of an object. Yes I could use equations (simple or not) but which do you believe is quicker, typing in an absolute dimension (20, 24) or an equation [(20/ 28)* 100, (36/24) * 100)?
