To change this, go to your left pane and click onto the “Collaboration” tab, expand the “Environment” option and click on “Ground”. The properties of the “Ground” will appear and half way down these options you will see “Ground Texture”.
The default entry (which creates the Dassault Systemes logo, if you want to change back at any point) is “%DS%”. To change this to an image of your choice click the entry box and browse for your image, click OK and you will see your image appear as the ground texture.
Hint: You may want to modify your image file to create a white border around your actual image/logo; 3DVIA automatically tiles your image file as you scale this, so to see your image nice and central, simply add a white border.
Also, as the name suggests, the image doesn’t have to be a logo. Try setting this as a ground texture (tarmac/grass/etc.), flick on the “Shadow” option in the ground properties and click to “Set the height on geometry”.
Finally, if you want to make the new image/logo your default for every document opened, you can do this through the “Default Document Properties”. Simply go to File, Properties, Default Document Properties and click on Viewport. On this page you will see the directory of the current image (again, this will more than likely be set to “%DS%”), browse to your image file and click Apply. This image then will be the default for every new document created.
