This week I had 2 calls from labs asking me the same question. In my eyes it tells me there might be others that experienced the same thing! Here is your answer...
When you design using the inLab 15 for a CEREC Office that will be milling chairside. If the Dr. calls you and says he can not mill the cases you designed because his screen only shows the admin but the model and mill icons are grayed out. Like on the picture below:
Now all of this could be avoided if when you receive the case via connect! You edit the restorations from the get go! Ask the Doc what material he will be milling in and you change it on your end.
Make sure you choose the MCXL
Make sure you choose the Material
When you export as a .dxd and upload it using the connect portal
