Hi Massimo, Nice to hear from another Allplan user. first of all where are you based if I may ask? I Initially imported the allplan model as a 3DS file in Vue without any textures assigned. Iwhen opened in Vue, I noticed a lot of numbers/materials/objects when looked at the world browser list. I only had about 12 or 13 drawing files and the default colors for Allplan does not exceed 30. But I noticed I had more than 100 material/object/numbers. I then imported the very same model with textures already assigned in Allplan. The result was the same thing. Again too too many material/objects/numbers. I would gladly email you both files if I can have your own email. There is a max. file size limit here. Also I would really appreciate it if you could email me a step by step exportation from Allplan to Vue as a 3DS with any options that i might need to check in Allplan. Looking forward to your response and thanks so much. Regards, Nick
