Need help- the drawing is rotated

[MisterJingles]

Hi guys

 

This is a real beginner question.

Here is a screenshot of a drawing in a format which I sometimes get given.

 

 

I cannot work with it without knowing why its orientated like this and how a drawing like this is to be plotted.

Out of urgency I just rotated it but its obviously not the suggested way to to it.

 

Can you tell me what the purpose of doing the drawing like this is and can it be reverted back to classic Autocad without any repercussions?

 

Regards

Rob

I would guess it's the UCS that's been rotated- try UCS- WORLD then PLAN and see what happens?

 

Reasons for changing the UCS might be to make it easier to work on particular parts of the drawing using polar tracking/ ortho/ drawing at relative angles etc...

This is how a site has been surveyed by the surveying company.

 

Drawings like this are useful for plotting on your requirements in the real world, in a real world position. i.e if you printed out the drawing as you received it and went to the site, the site would be orientated as per your drawing

 

They can be rotated for ease of use via the ucs command but i would strongly recommend that if you're not going to use this command and rotate it manually that you save a copy and keep the original as is.

 

This type of drawing can be used for taking off co-ordinates, accurately locating your proposed works against existing structures, drainage etc.

TIMMS - Ok I presumed it was something to that effect. Thanks.

My problem is that if I want to plot this I need to rotate it. Ill fiddle with the UCS settings and work out how to rotate it correctly. (After making a copy of course )

 

Thanks to you both

okay, what you need to do is:

 

type ucsfollow and set this to 1

 

then open the toolbar UCS, right click on any toolbar.

 

then select the icon "3point" which has an x and y axis with a line with the number 3 on it.

 

this will prompt you to enter a positive portion along your desired x axis. i.e the bottom of the page to which you want to orientate your drawing.

 

then it will prompt you to enter a positive portion along your desired y axis. i.e the right hand side of the page to which you want to orientate your drawing

 

The model space will then rotate itself to a new UCS.

 

then open up the UCSII toolbar, select the icon called "named ucs" and rename the new ucs to a name of your choice, i usually call this plan.

 

You should now be able to switch between world and "plan" ucs.

 

You'll need to keep open the UCSII toolbar but you can close the UCS toolbar should you wish.

 

Hope this is clear.

Rotate it, print it, close it. Why do you need to save a copy? It's redundant.

Rotate it, print it, close it. Why do you need to save a copy? It's redundant.

 

 

if you had a hardcopy of a drawing, for example, and you drew all over it or you spilt your coffee or whatever and you wanted to get another in original condition, you'd have one saved already instead of having to ask for another from whoever sent it to you.

 

why would you not want to save a copy?

[GE13579]

Why not just name the UCS then you only need 1 file?

[Timms_KHP]

yeah, could also do this.

 

I've just been bought up, in auto cad terms, to save a copy of any drawing that i have received. i know its duplication of file numbers but if for whatever reason the original file becomes corrupt etc i've always got a back up.

OH-MY-GOD! I didn't know I could rotate it back to it's original orientation!

If after printing the rotated plan, you close the drawing WITHOUT saving the changes, then it will be back as the original.

If you use DVIEW>TWIST you wont have to worry about rotating the entities from their original position. Once you have DVIEW oriented correctly for plotting then use UCS>VIEW to orient your cursor to that view. Save the view and set DVIEW back to zero. If you need to go back to that view for another plot restore it from the VIEW command.
