Problems exporting to Bryce

Hi all i'm just wondering if anyone can help me with the following problem. im trying to export a 3d drawing to Bryce and have followed the instructions given in the tutorial on this website. however, when i try to select the filetype, the .3ds type isnt there at all. According to the tutorial it should be. Can anyone help?

Hi Kev.... if i remember correctly you first need to export from Autocad your 3d model as an 3DS object file type and then open Bryce and insert the file.

I found this tutorial see if it helps

However the 3DSOUT function was removed from after 2007 so i think you have to download an 'add on'

Thanks for your reply, any idea where i can get the add-on??

autodesk website?.... google it... also i know its been discussed on this forum many times so you can search using the search funtion at the top.

Hope this helps

Yes i googled it and found it which is excellent but now i have another problem, when i try to import my model into bryce i get an error message saying "A file error has occured (i/o bad media)."

Anyone know whats wrong???

I know the 3DSOUT utility works in versions up to 2008. Does it actually work in 2009?

if it doesnt work in 2009 is there another way to export to bryce?

You can download and install a free program called Blender.

Export from Autocad in .dxf format, Import to Blender and then Export as .3ds format.

Other than that, I don't know?
