Troublesome DWG slow to open

[enthralled]

Hi,

Attached is a DWG drawing which is too slow to open.

Things I tried that doesn't fix it:

1- Recover drwaing.

2- Purge.

3- Copy entities to new file.

4- DXFOUT/DXFIN (gives error at dxfin).

Any ideas?

I think you overlooked a few things. Try opening this version. Any faster?

How did you do that?

I did a little house cleaning on your drawing as you missed a few spots.

 

Some of what I found with AutoCAD's help....

 

-PURGE > REGAPPS:

5 registered applications deleted.

 

-PURGE:

2798 zero-length geometric objects deleted.

20 empty text objects deleted.

 

-PURGE > ALL:

4 blocks deleted.

9 layers deleted.

3 text styles deleted.

 

OVERKILL found:

248 duplicate(s) deleted

823 overlapping object(s) or segment(s) deleted

 

The bottom left hand corner of your drawing has minus coordinates of:

X=-322134,2022, Y=-19573.7485

Is this because it is based on a survey grid of some type?

 

Bottom line. After I cleaned house I WBLOCKed the drawing out then inserted it in a new blank drawing with the lower left hand corner being set at 0,0,0.

 

File size now: 484KB. The diet worked.

 

Is this supposed to be a metric drawing by any chance?

 

Something else that is unusual. Some of your text has a "Z" value greater than 0.0000. Why? You alos have splines in your drawing with differing "Z" coordinates. Why? What am I missing?

It's an old drawing that I came across. The coordinates grid we use is Deir ez Zor stereographic (metric).

Thanks man!

Well that's not all. You have several lines (nine to be exact) in your drawing that only show up if you look at the drawing in an isometric view. Why? And I found text with negative "Z" values too.

You're right, strange drawing... I have no idea

Not very surprising though, given what clients usually send

OK...glad I'm not the one who has to work with the drawing. Good luck.
