where do I find a scale model global type function in WED, for example I would like to drop in a cube and size it to what ever size by entering a number (like 600) instead of dragging the edges or scaling it to some underdermined amount to try and get it close
Thank you

Select your object in WED, in the position tab by behaviours and properties you can scale your model numerically in all 3 axis.

not sure I follow, so if I want a cube say 30,000 in size, how would I do it?

The numerical scale in WED is percentage based. So if you have an object and set 200 in the scale boxes, your object will know be twice as big.

Just mess around with that position tab in WED.
