Unable to change Dimscale

[tim_newsome]

I am creating two base templates for my new company. I am trying to purge all unnecessary first. One of the first things I do is redefine some of the system variables such as dimscale.

I want to set dimscale to 1 in both the Existing.dwt and the Site.dwt I cannot change the dimscale from 0.0 What is causing that system variable to be locked?

Like me your current Dimension Style is probably Annotative. I'd avoid ever modifying any Dimension variables that would affect the current Dimension Style. Why are you wanting to modify it anyway?

Not trying to modify a dimstyle. I am creating a Civil 3D template that has Dimscale, ltscale, msltscale and psltscale all default as 1. that way it wont play trick with the annotative balance.

Dimscale not dimstyle is 0.0. Never seen that and I cant change it to 1.

Have you tried making a Dimstyle that isn't Annotative current and seeing what dimscale is set to?
Modifying Dimension variables create overrides in the current Dimension Style. Good reason to not do it!
The reason you cannot modify dimscale now is because you cannot assign it to an Annotative dimension style.

What is it you're really trying to do here?

Explanation from others may be easier to understand.

I see. When I changed the dimstyle to one that was not annotative then I have the option to set dimscale to 1

I use Lee Mac's Steal from Drawing to import Dimension Styles from my default template file with this macro:

^C^C^P(or C:Steal (load "StealV1-8.lsp"))(Steal (strcat (vl-filename-directory (getenv "QnewTemplate")) (chr 92) "AutoCAD Template" (chr 92) "Templates.dwt") '(("Dimension Styles"("*"))))) .regen

It could easily be added to acaddoc.lsp and used to import the Dimension Styles you prefer from one of your templates if what you want is to have them available in whatever drawing you open.

Creating Dimension Style overrides to the current style by modifying a Dimension variable looks messy and can be unpredictable especially when copying from one drawing to another.
