how can we jump 1:1 to 10:1 scale

hi every one, previous day one of the company send drawings in my office which is made on model space and his scale is 1:200 it is reduce scale, but my engineer said to me you have to set this one drawing on paper space and when i shift that one drawing model to paper space it was reduce so that time i thought i have to change the scale so i select enlarge scale on paper space which is 10:1..... so want to ask this

in one of the lighting symbol which is 1200mm in drawing of the full size scale 1:1.

so i want jump 1:1 scale to 10:1 scale

so i waana ask that block scale how many times..........

It's a bit hard to follow what exactly you are saying here.

So you were sent a drawing which was not drawn 1:1 in modelspace, but was drawn 1:200 in modelspace (not utilizing paperspace at all I assume)?

I'd scale the modelspace down to 1:1 and then set up your paperspace viewport accordingly at the desired scale. If you had a block 1200mm in size at 1:1 supposedly and want to increase its size by 10, simply scale the block (X,Y and Z Note: Unless the Z value holds elevation etc) by a factor of 10 also.

Add some punctuation, please.

sir i want to know only and only that.... how can jump reduce scale to enlarge scale like this...... 1:1 to 10:1 or 1:1 to 4:1

Unlock Viewport and change the scale
