2012 Civil 3D Paper Space Viewport Question

[nok092]

Hello My name is Mark and I am a Civil Engineering student at UTSA.  My question is:  In model space I have inserted 2 surface models.  In paperspace I have inserted 2 viewports to correspond to those models.  I have created a profile view of an alignment I made on one of the surfaces and when I made the 3rd viewport in the paperspace to show my profile, it comes through pretty messed up looking.  When I try to scale it appropreiately it changes the scaling of the other 2 viewport models.  Click the attachment to see what I am talking about.  Any help is much appreciated, thank you.

Leave the modelspace scale set to whatever you started with. When creating a new paperspace VP you need to set the scale desired in that VP then REGEN to get the C3D labels to scale correctly.

Just an addition to Jeff_M's post, if I recall correctly you need to be inside the viewport when you regen. For clarity:
1) Go to layout and create viewport (make sure you have the paper size set up correctly too)
2) Set viewport to correct scale
3) double click inside the viewport and then hit regen

Another alternative, user REGENALL.  No need to enter any viewports.
