ADT to VIZ 4

[bully712]

I'm having a problem exporting extruded PLines from ADT to Viz 4. You can see what it's doing in the 2 attached images. I have no clue why it's doing it, and it's starting to drive me crazy. Does anyone have any ideas to resolve this issue?

 

Thanks

As far as i now, an extruded pline is a solid...no?....show in 3d, maybe you have a pline with a thickness, i never do that.

Anyway you shouldnt be exporting, you should be importing into VIZ or better yet file linking.

If you are importing a dwg to VIZ you shouldnt have these problems, and if you are, i would suggest a re-install or try saving as a R14 or R2000 dwg.

The bottom line is don't waste time trying to figure it out, especially if you have a deadline.

Also the geometry looks simple enough to replicate in VIZ in the amount of time you would spend trouble shooting.

when you export from autocad dxf it gives you the option to cap or not cap extruded plines. thats whats it's doing here. another quick solution is just to select the caps in viz and erase them.

Do you mean the fact that the foot print has changed or the fact that you can see the diagonal lines of the triangular faces. If you mean the latter its because when you extrude the Plines they become 3 dimensional and each side is made of a face which when exported to viz the faces become triangles ( I'm sure you already know that.) If you mean why has the foot print changed then I'm not sure.

(Island J) My PLines don't have any thickness to them. I export an extruded PLine to a .3ds file, then I import the .3ds into VIZ 4. I'm pretty quick at doing it this way, and I've been doing it for 6 years now with no problems until we switched to ADT 2004.

 

(tdarcy) Yes I do mean the Foot Print. I know 3d objects are made up of triangles. I just don't understand why the 3d Solids are shifting like that.

 

It seams to be doing it to only angled lines. All the rest seam to be fine. The images are of a column, but It's just a small fraction of the building. I would like to avoid re-modeling it in VIZ, being that this building has to be precise..

 

Thanks for responding, and I hope we can get this resolved..

(Island J) My PLines don't have any thickness to them. I export an extruded PLine to a .3ds file,

No thickness but extruded? same thing. they do have thickness. ADT is identifying closed plines and boxing them out.

 

either explode the plines first before 3ds export, or export as DXF switching off capping.

You could try just importing the dwg. file into viz rather than exporting from ADT, I usually do it that way.

ok... I've attached the ADT file below..

 

1. open the file, and draw a PLine around the red lines.

 

2. select the PLine and extrude it to 5'

 

3. select the extrusion, and export to .3ds file

 

4. import the .3ds file into VIZ

 

5. go to the top view a see what you get

 

dwg files from ADT don't show up in VIZ 4 thru exporting

 

Thanks and let me know what you get

 

A few of us a work think that there is something wrong with the file itself..

just tested it. and ur right, it dissappears in viz. because....

 

your acad file is too far removed from world ucs 0,0,0 (do an ID on your model and look at it's co-ordinates from the wcs 0,0,0 origin) so when it's imported into max/viz you cant see it. viz/max has trouble with this subject.

 

now in autocad, move the whole drawing from where it is, to 0,0,0 then try exprting again. this time it works fine

STRAT:

 

I just figured the same thing out a few mins ago, then I read your message

 

It was around 1.7 million feet off..

 

It's been driving me crazy the past few days. Now I got to remind the Architects to draw there floor plans at 0,0,0.

 

Thanks a million for your help!
