3D shape shifter

[PBCAD]

autocad 2009
***"CORRUPTED" DWG ATTACHED***
***PICTURE ATTACHMENT INCLUDED***
created a 3D part (which was 1/4 of my final assembly)
since it is symetrical, mirrored that to get my final assembly

(do not want to union the 4 parts)

when i saved my file and re-opened it
some of my parts were deformed,
my complex-smooth edges were missing and the side had become a flat surface
***refer to picture attachment***

extra info:
I created the model the way I wanted
then saved it
opened a new file and xref it in, it looks perfect
but when I open the original file again, there are extra edges

also when I open that original file, as autocad is still loading,
the model appears the way I want
but once autocad is done loading, the extra sides appear
-------------------------------------------------
-tried opening it on diffrent computers w/ different graphics cards
-tried re-creating on different computers
-tried using copy and rotate instead of 3dmirror

Use AUDIT command for any bugs.
The object is construction as a surface or as a region.?

AUDIT didnt find any errors,
by region if you mean solid = yes

It looks like the "solid fillets disappear on file close/open" problem.
It has been mentioned around here a couple of times before.

I did a search but this (http://discussion.autodesk.com/forums/thread.jspa?threadID=696179&tstart=135) is the closest I found and it doesn't help.

yeah except my shapes were created using sweep of two sides and intersecting
but autocad might be interpreting both of those methods the same way?
..either way ill try to recreate it using fillets
but for now, thanks

as for that link, im dont think its network related..because my autocad is not on a newtwork

original post updated.

Your update suggests that the model is still correct but its display is wrong.
Does changing things like viewres, hideprecision or even your Windows display resolution make a difference? How does it look in a plot preview?

changing VIEWRES didnt work
changing HIDEPRECISON didnt work
plot preview shows the 'deformed' object
tried multiple windows resolutions, still no difference

thanks,
still open for any suggestions

Change facetres = 10
In command line type: -shademode-->g

FACETRES
or
-SHADEMODE
didnt fix the problem
-SHADEMODE>G = cool effect though

i want to find a solution for this so any ideas are accepted :)
also if you need any other info, please ask

For trouble shooting try to create a layout tab and set a view that is screwed up and create a solid profile using solprof, and turn off the layers of your solid and see what it does. AutoCAD has a lot of issues with complesx 3D objexs with multiple curves. What about in a render? Have you rendered the object to see if the result is still deformed. It appears to be a problem in the processing of the object. How to fix....SolidWorks...... You may have to break the object down into even smaller components and see if it still has the problem. I do not believe it is the video card as much as it is AutoCAD. Hope this helps.

Would you post a file here containing just the problem part?

"CORRUPTED" FILE

[jaberwok]

I turned on solid history display (SHOWHIST command) and it's a mess. Each real section contains history from 2 of the other segments. I don't know how you got to that point.

Anyway, I deleted 3 segments leaving one that I think is how you wanted it and mirrored again to get four segments. I saved and closed it and re-opened it and I think it's okay though the old solid history has been lost.


Edit: yes, I did see the correct shape whilst the original file was loading.

k, thanks so much
i tried save and re-open it was fine


,so the method i used to make this was, used front and side line profile, and extruded both of them
then i used intersect to get the nice curves,

is that a 'bad' way of doing this? what would you recomend.. or where did i go wrong?

thanks again

[jaberwok]

I'd use the same method to make the shape.
I'd guess you may have had several goes at copying, mirroring or somesuch, possibly with lots of undos in between and the solid history got confused.
