Small Blocks in Viewport... HELP.

Can anyone help me with this?

I have a lot of blocks on a drawing all drawn in model space. They appear fine and the correct size on the model space. Now when I go over to my paper space with my borders these blocks are significantly smaller in the viewport. All the lines and other items are ok just the blocks which have been brought in that appear smaller when looked at through the viewport.

Is there a command or anything I should use to get the blocks to appear the correct size?

as a test if you explode one of the blocks then look at through viewport is it the correct scale?

yes, i've just exploded one and it appears the size I want it in the viewport?

What should I do next. I dont wan't to have to explode them all.

No i don't want you to! :-) it appears that you have a problem with annotative blocks. Have you set them up to be annotative?

send me your drawing if you want i will take a look and will be able to sort it for you.

I'm not sure if they are annotative, how can I check?. They are selected from a toolbar the company has set up which was created a long time ago. They appear ok when they are selected on any drawing i've ever done. An apprentice has set this one up, so I dont know what he's done.

You can check by clicking on the block then loking in your properties tab under MISC and it will say Annotative Yes or No

Yes they are annotative. How do I send you the drawing?

I have messaged you my email pal

ok you have the block set at 1:50 annotation scale but your viewport if set at 1:20.

However you have a problem as the block Pipe_2Way_Valves_Closed_01 has been designed too small and if you insert them with 1:20 scale they will be too small and look exactly how they look at the moment through your viewport.

To solve the problem i would suggest that the original blocks need to be increased in size SCALE reference 20 to 50, this will not however change the current blocks in your drawing. Go round and scale up the blocks for now as i think you have already done a few.
