ZeroRotation.lsp Set rotation of objects to zero (based on current UCS)

[alanjt 10]

A request in another thread made me dig this up and do a little updating. I thought I'd post it for you good people.

 

This will rotate all selected MText, Text, Multileaders and Blocks to match the current UCS (basically, rotates everything to zero).

Alan,

 

Cool program, I'm not sure if I understand what it should do. I drew some text at various angles and ran the code which rotated the text to 0 degrees. That makes sense.

 

Then I set a UCS on an angle and tried again, but the text did not rotate.

 

Should the text only rotate to 0 deg in its own plane, or is it supposed to be able to change the plane of the text as well?

 

I guess a diffferent way to ask my question is - is this a 2D or 3D application?

It's a 2D application. I have very little experience with working in actual 3D. Civil 3D is all 3D models, but for actually display purposes, you just show the plan, profile and cross sections. I'd have to play with it to get it to work with a 3D plane.

This is exactly what I was looking for. I have tried to create my own, but without success. Would you mind sharing the file?

 

Thanks in advance

Oops, forgot I'd removed it. Code re-posted.

Thanks and have a great day

Thanks and have a great day

You're welcome. Come and hang out. Since you have but three posts and they all were made today, I'd welcome you to the forums, but I notice you've been a member for quite some time.

cheers alan, this will be quite useful.

Alan,

 

Nice idea for the program

 

But be careful when the UCS plane is not the same as the WCS plane, since the UCSXDIR System Variable is expressed relative to the WCS plane.

 

An example:

 

 

The fix, change:

 

(setq xdir (getvar "ucsxdir"))

to:

 

(setq xdir (trans (getvar "ucsxdir") 0 (trans '(0. 0. 1.) 1 0 t)))

I would also be inclined to bound the UCS Angle to a variable prior to iterating through the SelectionSet to save recalculating the angle each time.

Yes, I know and I know the fix, but if you had noticed, I hadn't updated this program since late 2009. However, since you pointed this out, I went ahead and gave it a complete overhaul. I even noticed that in April of last year, I had updated my AT:UCSAngle subroutine to work properly. Oh well, I never noticed, but it should be good to go now. Thanks for the nudge to update.

 

Updated in first post.

Just making you aware...

alanjt et al,

 

I am trying to modify this code to allow for the rotation of block content in MLeaders, however, I cannot find any VLA properties or methods associated with the rotation of block content in a multileader. I am using the following resource as suggested by Lee Mac in another post:

 

C:\Program Files\Common Files\Autodesk Shared\acadauto.chm

 

A really good resource which I never knew existed - Thanks Lee Mac!

 

Cheers,

If I remember correctly, the rotation property of a block within a MLeader wasn't available. Actually, looking at one in the properties palette now, it's not even available there. I don't use many MLeaders with blocks, but for the few I do, if I do have to rotate them, I just use the rotate command. I didn't code this in because using rotate doesn't really work the same as 'put'ing a rotation, and since you don't really have a rotation to extract to begin with, there isn't much to work with on a reference for your new rotation angle.

If I have time, I might dig into it some more.

Alan,

 

Thanks for your response and explanation. I had an inkling that this would be a manual task.

 

In any case, a great routine which sits at the forefront of my custom menu. If I could count which lisps are used the most, this would be up there - Top stuff! I also like the AT:UCSAngle function.

 

Cheers,

Very good programm! But I have a question. Is it possible to rotate All the entities, as mentioned in a first post, to zero relative to current UCS?

[funkkybebel 10]

I have got used to rotate the cursor (to simulate UCS rotate) with Lee's lisp "CursorRotateV1-0.lsp".

I though it would work with that, but no. I have to totate UCS to make it works.

 

Thnak anyway, it's really useful.

Thanks for your lisp alanjit, if possible could you please look on to my request posted(Lisp required to make text rotated to 0 angle & make changes in font style & height)?

 

i need a help in creating a lisp, actually i have drawing with lot (nearly thousands of text to converted in a single drawing file) of text to be converted from different angles to zero angle & also to change its text height & font style as shown in attached .dwg file,

Another important thing is i need to remove the / symbol from that text & re-arrange as shown in the attached .dwg file.

Kindly look on this & requesting to please provide lisp for this work.

Also to remove the text P50/ ,like whatever text starts with P & ends with / to be removed.....is it possible? please help urgent help required.

Dear alanjt ,

 

Works perfect. thank very much.

[danglar 10]

Is it possible to add polylines to set of entities for zero rotation?

probably based on this approach?

now it works only for Blocks ,MTEXTs,*LEADERs and TEXTs.

With this addition it can works for polylines too
