issues with importing DWG from Autocad

[Guest syp]

Hi .

 

Since ever... when i import DWG plans into 3dsmax (201164bit)

it imports them on x: 17920000, y: 66220000 (instead of origin > 0,0).

which makes 2 issues,

 

1. max does not like objects far from origin, which means he shifts all the splines a bit which makes them not correct..

 

2. if i try to goup them together, so i can move them easly to 0,0 it also shifts everything.

 

 

i found a temporary solution by picking the whole dwg (all related layers) and moving it with the xyz field on the buttom - and im moving them in relative space.. (which helps)

 

but for some reason i still get slight shift in splines on some layers :\

 

as far as i know the original DWG is built origin point... but im not an autocad expert..

 

for all the ideas of importing the dwg as a block and then moving it >

** i gotta import the dwg into different layers because i need the different colors on the splines.

 

any ideas?

cheers!

Are you sure the dwg is drawn around 0,0? Isn't there a relative or temporary UCS that makes it look centered whereas it's not? It dosen'r make sense; I've done that for years with no issues at all since Acad 2004.

 

 

Can you post the dwg to take a look?

[Guest syp]

thanx for your quick response, ,

so im attaching one of the DWG's..

 

my 2 main question are..

 

1. how do i check what is the real position of the drawing.. + how do i move it to 0,0

2. im using Max2011, which format should i save the drawing... cad07, cad12, 13?..

tnx

1. Just type UCS and hit enter twice. That should get you back to the real world UCS. Then you can draw a line and type in 0,0. That end of the line is the origin. How does it relate to your drawing? Make sure all layers are on. Select all (ctrl-A). Move. Pick a nice point in your drawing (the corner, the center, that lamp post...) type 0,0; that point will move to 0,0.

 

While you can move the drawing to the origin almost as easily in Max, I'd worry that the geometry would already be messed up at the import stage beforeyou get a chance to work with it.

 

2. You should be able to save the drawing to whatever year your max is with no trouble. But I don't know if there are known issues. If you run into trouble, you can probably safely back down a few versions, say 2010, if you don't have any really modern acad features in use.

Tnx!, ill try it !

So, i tried to do it in cad.. something did not work.

 

1. when i created the line at 0,0 for some reason it went off screen and i cant even scroll to it as if it's "too far"

2. i selected everything typed "MOVE" then "0,0" and it said: "Dismention disassosiated" + 2 more errors with the word "disassosiated"

[Guest syp]

could you specify a specific tutorial?, i didn't plan on learning whole autocad... im just using it to clean and import my drawings

 

tnx !

dwgs are my worst nighmare

first thing i do with a dwg is screencapture it - then delete it forever

Zoom Extents

Type Z, then E. That's (Z)oom and then (E)xtents. That will show everything on your screen if AutoCAD decides to draw something past it's limits.

 

The fastest way to get CAD back to 0,0 is to do it inside AutoCAD. Just select your cleaned up line work, hopefully you are not importing everything. (Type LAYOFF to activate click-hide of layers and that will speed up your CAD cleaning process.)

 

Once you have everything selected, type MOVE, specify your base point (where you want AutoCAD to move it from) and I usually use the lower left corner just for ease of use, then type in 0,0,0 to move it to World 0,0,0.

 

Save it, or I tend to WBLOCK things so I only save exactly what I have selected. Your file type doesn't overly matter but I usually save to AUTOCAD 2004 so the line work file is literally compatible with any version of Max in the last 8 years. The only thing is that your AutoCAD version is at least the same as your Max version. If you are a higher version in AutoCAD then you must save your DWG as a the Max version. Say, if you have AutoCAD 2013 and Max 2012, then you'd need to save lower from AutoCAD.

- scott that was really really help full , thank you so much

 

Tnx ya'll... im gonna try it and repost

don't forget to hit F3 to turn on object snap, if is not already on.

[salvador]

The line from your drawing to 0,0 didn't work for you because sometimes AutoCAD won't reach the whole thing by Zoom Extents; in this case use Zoom All to see everything.

 

As suspected, the drawing was far far away from the origin. There is still something preventing me from zoom extents to only the building, but your drawing is now CORRECTED. Hold on I'm uploading it for you. . . .

 

CORRECTED DWG

1) Open drawing RCF-pl-01_CORRECTED

2) From the Home Tab go to Layers and Unlock layer AX (it is only some hash lines)

3) Type QSELECT

4) Select as follows:

5) Press Ok (Will say 9 objects selected)

6) Press on the keyboard

7) Go to the View Tab

8) Select to view either “All” or “Extents” with just about the same results

Draw a line form 0,0,0 to where you are in your drawing and then zoom extents.

[salvador]

1) Open drawing RCF-pl-01_CORRECTED

3) Type QSELECT

4) Select as follows:[ATTACH=CONFIG]48107[/ATTACH]

8) Select to view either “All” or “Extents” with just about the same results

 

I knew it ! I missed that one ! The problems of trying to make things too fast. Thanks Ismael

[salvador]

Ok. There were also three frozen layers with objects. I removed everything far from the origin and now it's peachy.

 

HERE'S THE CLEAN VERSION

[Guest syp]

wow!, you guys are great!, thank you sooOoo much!

[salvador]

Glad to help.

 

You should import fine into Max now. Yet, if you're still having trouble, call out again.
