You cannot change the scale with the viewer. It's for viewing onlyOkok, and how can i know the scale on the soft ? and if the scale if good for me ? I can just see when it's printed ? sorry, i didn't find a really good answer,i don't know the soft (i have pep viewer)
And thx for your first answer
You can however see the assembled size shown in the bottom right hand corner of the window.
If you want to edit your files and change the scale you'll need to buy the designer (it's not expensive) You'll be able to scale them to fit you exactly then (n.b. obviously add some leeway or any helmets/armour etc.. will be too tight to put on. Decide how big you want it to be based on your dimensions and go from there.
But as said, you cannot scale in the viewer, only the designer.
