How large is my model
 

How on earth can I see how large my model is (centimeters etc.) ?

I need this for cloth solving.

I don't have much experience with cloth, but I believe that is in regard to how large you want it to be... if you're making a human, and you want the human to be 6 feet tall, you use that for your cloth solver to act realisticly for a 6 foot tall model...

Just my guess.

Hmmm... you might be right mike.

The manual speaks alot about the distance of your model. Just thought the axis could tell something about how large my model supposed to be... !?

Well, I tend to set units of measurement when starting a project by going to windows -->settings/preferences --> preferences -->settings. Each grid square will represent 1 unit. So, if you set it to inches, each grid square will be in an inch. Then, you can just count grid squares or figure out the model size beforehand.

I'm not quite sure how this works along with grid options (display --> grid option box). Maybe someone else can shed more light on that.

I've found this helpful when building things to scale...like making wood planks that I want as 2 x 4s and what not.

there is a measure tool for the grid units.... create -> measure tools, distance tool

but i dont think it will help you here, but a tip anyway
