isometric

[tcdavis]

Hi...I have not done much isometric work for quite a few years now but i have a new company i am doing some freelance stuff for and the last in house person did all his drawings as isometrics. My problem is not working in isometric but when I switch to paper space..how do I convert those isometric drawings to regular 2d?...this might be basic stuff for some but like I said I havent done this in quite some time. Any suggestions?...oh..they are using AutoCadLT 2005 & Building systems MEP...I usually use AutoCad 2000 at home.

 

Thanks

Chris

u can convert 3d objects to 2d using flatten (not sure if LT has flatten command tho)

[tcdavis]

No..just tried it. thanks though.

Maybe I'm not understanding what you're asking? Isometric drawings are just 2D representations of 3D objects. They just give the illusion of 3 dimensions. They are already flat. Sorry, but there is no way to "convert" an isometric drawing into a plan view or elevation or whatever view you need. You just have to redraw it.

yeh iv never seen a 3d iso before so make sure u have a look in the model n change views, i think u'll be happy to discover that u already have wat ur lookin for

[tcdavis]

its when I change to paper space for printing and the original drawing is in the isometric format still...but I need it to be in the standard 2d view.

not sure i follow maybe attach some images to show wats happening

Not sure if this is what your after...

 

SNAPSTYL is the system variable for isoplane (0 - normal, 1-isometric), you could customize

a button with "SNAPSTYL 1 " for iso on & "0" for normal.

If it is indeed a 2D Isometric drawing then here is a semi-affective, semi-ineffective method. As previously stated, it may make more sense to just redraw.

 

In the attached, the layout “Front” has a viewport tweaked to allow for the orthographic projection.

Maybe moving to 3D modelling will help.

 

It avoids a lot of pitfalls.

Can you post a screen shot?

[tcdavis]

Thanks for everyones help. Unfortunatly I havent been able to resolve this. Looks like redraw will be my only option for now.

well if anyone is still interested I have figured it out inadvertantly with some help from one of the Cad tutorials...just had to go into ddvpoint and change to plan view.

[Strix]

Can somebody explain for the benefit of the thread how that works please?

[Cad64]

I think he may be referring to this tutorial: http://www.cadtutor.net/tutorials/autocad/basic-3d.php

 

I didn't know DDVPOINT was available in LT though?

does this answer that question?:

sorry been away for a bit...yes it is available in LT...not on any drop down menu but at the command line.

Hey Chris.

 

So what did you eventually do, I am finding myself in the same situation with a wiring schematic. Was drawn in 2d Isometric to represent 3d, but seems like a waste of time to redraw.

[tcdavis]

If you type in ddvpoint at the command line and then click on "set to plan view" it restores the 2d view.

I saw someone doing the following:

- make a drawing on top view

- go to sw isometric

- export that isometric view as if it was a top-view drawing

 

That was awesome to pick up some architectural drawings and use them as a base for piping isometrics. Can anyone remind me HOW that is done?
