Working in Real world UCS problem

660 Views, 6 Replies

I am working on a project that has been placed in real world coordinates and is a different angle than true north.  I can change my ucs and route pipe with almost no problem. If I continuously route a pipe in both horizontal and vertical directions the pipe will remain perpendicular or parrel to the way i am routing it.   HOWEVER! if I stop routing while inserting a vertical pipe, then click on the "+" grip, when I want to change plane and add an elbow the compass revits back the the ucs being world and will only put in the eblows on the world coordinate plan and not the plane that I am working in.

 

So, is there a way to change my compass orientation while routing pipe?

Well after some out of the box thikning I found a pretty good work around for this on my own.  If your site is skewed say 10 degrees from north and you want to work in real world coordinates, you can turn off your compass snaps, turn on polar tracking and add the angles you need to your polar tracking dialog box.  So I went and added 80, 170, 260, 350 and know when i route pipe, it will align to those angles in model space allowing me to place pipes in real world with out having to change my ucs either.  Obivously for different angles like 45's i will have to do the math for those also.

 

 

Even tho I have a solution, I would like to keep this topic open incase someone else gets a better solution.

I have the same problem with my project.

Did you find some solution?

We were having the same basic problem so we decided to rotate the model to a Plant North. We chose to go this route because we couldn't think of any other way of getting orthographic elevation views to show perpendicular to the view. Ortho views will only look N or E or S or W. You can't look N10E. If anyone was able to come up with a solution other than rotating the model, please pass that info on. It would be hugely helpful...

You can make your own views in 2014 now, they don't have to be N S E W. Plus as well with Extension 1, you can have offset coordinates in the Project Configuration

Try this:

Set UCSFOLLOW to 1

Rotate your UCS on the Z axis to desired angle

Set UCSFOLLOW to 0

Route pipe

 

When done:

Set UCSFOLLOW to 1

Change UCS back to World

Set UCSFOLLOW to 0
