Title: Associating a block to viewport scale
Post by: bdough15 on April 25, 2012, 11:14:53 AM

I have had a request from an Engineer in my office to create a scale block that associates directly to the Viewport Scale.  That way we "never" have a problem with the scale block being incorrect again.  Our Current Scale Block is older and has been brought forward for years, it is a basic attributed block.  Does anyone have any suggestions as to how would create a block that would link directly to the viewport scale?

I have done through code where you create a scale block with visibility states to match different scales, and when the viewport is modified it.
 
This was just simple example http://www.theswamp.org/index.php?topic=38480.0 (http://www.theswamp.org/index.php?topic=38480.0)

You can give this a try as well. Uses fields in an attributed block. The precision is controlled by the luprec variable.

Thanks Alan. It was fun to write ... I may even adapt it for my own use  :-)

In Civil3D 2013 and Map3D 2013 there is standard functionality to have scale bars, but also north arrows chained to viewports.

So then really I should just wait a few weeks and use the functionality in C3D 2013.  I think that is the best way to go, don't reinvent the wheel on a clients time.

But you did not reinvent the wheel, I did  :roll: so no "clients" time has been used.  :-P I guess it will be a good tool for non Civil3D users.
