ADT2007 to Max9 = huge files...how come?

[Greg Steckler]

I've got 1/2meg .dwg that balloons to 60-100 megs when in max9. How come? 120 fold increase or more? I can see a 5 fold or even a 10 fold...but 100+????

Could you elaborate on what exactly is in the file?

This is fairly normal. Inside ACAD the data it handles is parametric meaning they exist only relative to each other and mostly composed of POLYLINES, SOLIDS and surfaces that created the 'data' still there just hidden or turned off in the layers.

 

When you import that in Max everything is made 'concrete' and every surfaces is now triangulated to follow the 'CURVES' and lines of ACAD specially if u set the tolerance/curver deviation high during import.

The drawing is a 7 story hotel with lots of windows, doors, railings. I've gutted the drawing of interior walls and any extranious interior objects. I changed all the railings to 4 sided rails as opposed to round or octagon balisters every 4 ". I did a purge, audit and made the wall style very simple. Several of the folks in the max Forum have been helping me get the polys, vertices, and size down but even so a 100+ bloat seams crazy. But I am really new to max so maybe I'm just naive. Here is a link to the file if you're inclined to take a crack at it.

I'm sure it is some settings I have too high in the File Link Manager or something. It could be Max9....the max folks (they are using max8 or 7) are all coming in at 66 megs but the best I've gotten so far is 102 Megs

 

(Please forgive as this is a bit of restatement of my plea for help over on the Max Forum). So I just thought I'd ask if a 100+ bloat is normal?

 

Arnold, what would you suggest for import settings specifically?

Hi,

 

Don't know if this will help mate but have attached the File Link Settings I use in Max for you.

 

EDIT: on the advanced tab all I select is Layer, Blocks as Node Hierarchy

Hmmm....well my settings were the same except for the curve setting (mine was 10, yours is 20) so I changed to yours. I did a simple roof dwg for the hotel(a large flat and several hips and gables) and the ACAD size to Max size is about 1 to 4. Much more reasonable than 1 to 120. The mystery continues....

Is Max dealing well with blocks and AEC content? I haven't tried full-on ADT files to Max in a while, and not at the scale you seem to be doing it at, but if you took all that 3d AEC content that's described parametrically under the ADT system and translated it to 3d polygon data, I'd expect your file size to jump alarmingly.
