Isometric Drawing

Hi,

I have block and text, that i need to display in a iso view drawing, in different planes. (2d drawings)

 

My collegues to do that must recreate symbols and text, and correct them with correct angle (oblique, rotation , etc).

 

Is it really the only way?

 

Isn't there the ability to toogle my drawing (text, or block, etc)beetween isometric planes to view them in accordance with the plane orientation? Just that easy?

****, if not, this is really paleolithic !

Sure you can change your view so that you are looking at a 2D object from an isometric angle but AutoCAD can't change a 2D block to isometric for you.

Drafting is a breeze and Revit doesn't always work the way you think it should.

You could maybe make a block for your text with different visibility states for the different views and then switch the visibility state when you switch views. You'd have to switch the visibility state manually but it might be quicker once you set it up. Depends whether you have standard annotations that you need to use or if all the notes are different for each drawing.

Draw an object in 3d and you can get 8 different isometric views almost instantly.

 

To convert a 2D orthographic view to one plane of a isometric view requires only a bit of customization involving projection math.  Go for it.

 

One way to kludge it without customization for a top plane is to rotate the objects 45 degrees and wrap them in a block. Then apply the following scale factors to the block:  xs=1.22474487, ys=0.707106781

It’s not clear what you have and what’s your goal.  “I have a block and text…”. Is that an AutoCAD block or an object that looks like a block? I assume it is 2D.

“My collegues to do that must recreate symbols and text, and correct them with correct angle (oblique, rotation , etc).”  Should this be interpreted that  you want symbols and text to be reoriented so that they appear in an isometric orientation? Are you hoping that AutoCAD can use AI to create a full isometric view from a single 2D, or collection of 2D, views?  What “correction” are your colleagues needing to make to symbols and text? Is it that they have a isometric orientation and you want them to be orthogonal to the screen?

The AutoCAD viewing options (e.g., SW Isometric, SE Isometric,…) will give you an isometric view of your 2D (or 3D) geometry.  If you want to reorient the geometry to an isometric orientation  (and not just the viewing angle)  you can use the rotate3d (not 3drotate) command as follows. Rotate3d the geometry, dimensions, text, by +45° or -45° about the Y axis then rotate3d the objects by -35.2644° about the X axis.  Note that rotating geometry yields an isometric projection that is about 82% the size of an isometric drawing. 

A sample drawing of what you are getting and what you want would be helpful in determining a more efficient workflow.

Short answer is no, its not the only way. 

 

The problem is that you must start with the end in mind. If you are starting with an iso and trying to walk it backwards then there is no way of doing this out of the box. Not saying impossible but i have not come across anyone who has done it programmaticaly. 

 

To achieve what you want (at least what it sounds like you want) to do you must draw in 3D then create your views.

 

If you are dealing with a seasoned drafter generally in my expedience let them do the different view isos. (as long as its not against policy) Time and resource wise some times its the best path forward. You have to let the job /client dictate the the pros and cons.
