Hey children!
So I've been taught this once or twice and I feel like I'm doing what I was taught but not working.
I designed a 3 unit screw retained bridge. The screw access hole will be right in the contact area of one of the abutment crowns and pontic. So I was told to design it and save the scene of the bridge and jaw. Then start a new case and call all the units anatomic waxups from digital copymilling. So i start designing and import the already designed bridge and get to the point of the design where it adapts to the pre op and the two abutment teeth morph just fine but tthere is no pontic/middle tooth. I have no idea why.
Ergo....I am here to ask my humble superiors for help.

Muchas gracias
A bit late to the party here, but whatever. Somebody will find this useful. Hopefully.
There is no reason to do it this way (make it, then save it and import in another project for copy-milling).
Here is what I do when I have a case where the implant is between teeth.
Depending on that version of exocad you have, you may -or may not- have this option available.
If this option is available, set the job normally, and set Cervical adaption to "Preserve tooth library shape" (default is "Pull to margin")
The wizard will make the teeth that are on the implants look like pontics, go through all the steps (place, free-form, shrink, connect),then it will create a virtual waxup of the entire bridge and attach it to the implants. Doesn't matter where the screw channels are.
If you don't have the above option on exocad (which your screenshots lead me to believe),here's how to do it.
Setup the job, nothing special.
Start designing, and on the step where you place the teeth, go on expert mode.
Right click on empty space and select this.
You'll get a prompt, click yes. This should be the result.
Now we are in the same place I described above. Restart the wizard and finish the design (place, free-form, shrink, connect). The wizard will do the rest. You will have the option to free-form the entire thing before the screw channels step.
Here is the finished design from the above pictures. Metal framework in my case, but it's the exact same steps.
Let me know how it goes if you try it.
