Thanks Josh.
Sometimes (pretty much always) I think it's so easy it's hard and complicated (forced smile/grimace face emoji)
I'll give 'er a go

I think if you name your wax up as "pre- op" in DB and after you are done ballpark shaping the proposed veneers when you click next there will be a " adopt to pre-op. Click on that and the veneers will morph into the shape of your wax up as individual units. Then when you click next you get another chance to adjust the veneers.
One thing, after you scan the wax up, before merging(in Medit software) on the wax up scan, cut away everything except the veneers. That way it's easier for the software to merge the wax up to the workind model. So dont do copymill.

here's a real Exocad pain in the as$. I set the full lower case up but forgot to select green ball to bridge each unit together. When I noticed the mistake I did expert, change type and turned the balls green. the most distal crowns are cantileveer pontics. i've done this before with other bridges.

So, I finish the design and without doing a really good double check to make sure all the crowns are actually on the bridge, I just nested and milled. Pull it out of the mill and the cantilever pontics are not there!! I load a 3d preview of the saved file and they are not there. Why didn't it attach and save the pontics?

Cuss my life and the poor decision to buy exocad instead of upgrading my 3shape right? What's going on here? 1602984075141.png 1602984305427.png 1602984452477.png

Riley, cut your losses and get back to what you know best.

This is the software's fault Boring

The reason the pontics weren't connected to the merged resto is you didn't connect them. If you were doing something other than a wax up/copy mill for that bridge you would have been prompted to add the connectors in the design process.

One way to fix this without deleting merged parts. <---- this is a way to make your situation worse if you are not familiar with the process.

Save each pontic separately as stl. Choose the top option in the prompt window for which coordinates to save in.
In expert mode, add remove mesh, since you don't have a preop already, import those pontic stl files you just saved as preop mesh. After importing, still in expert mode right click one of the pontics, select free form scan data. Add to the mesial of each pontic to make a nice broad connector. Make certain the free form addition intersects the distal of your bridge.
Once you are happy with the connector size save the cantilever pontics again as stl in the same coordinates.
Continuing in expert mode, right click on the bridge, select free form restoration.

In the free form window navigate to ATT,
in the library drop down menu scroll to 'add from file'.
Navigate to the CAD Data Pt. folder you saved those pontics in if it doesn't open automatically.
Double click on the pontic file. Click apply, click ok or next. When prompted select yes when asked if you want to save your free form changes. The software will recalculate the restoration with the pontics attached and save a merged bridge.

There are several other ways and/or shortcuts to do this, but this is a pretty safe way until you are more familiar with the steps.

People like to gripe about the exowiki and how brief or outdated it is. It explains all the basic software functions pretty well and concisely. I still reference it when I haven't done a certain type of whatever in a long while.

I just started finishing a PMMA case similar to yours. Noticed something weird, the cantilever, bridge abutment and pontic were not included on the milled bridge.
I connected them all, I know I did.

It merged into a bridge.

Just not connected to 6-8.


Doh4.png

There is that section sitting all by itself. I missed it when sending to CAM.StonedHahaha


Doh3.png

Finally after double checking. Merged to 6-8.Ciao


Moral of the story? I'm glad I edited out all the pay attention to WTF you are doing, stupid mistakes, blah, blah, etc. before posting my reply last night.😖

There is more options to fix your F#ck-ups in Exocad that I'll ever learn in my lifetime!! Once you realize you messed up, back up to the final free-forming stage and switch to Expert. Then there is an easy way to add connectors by highlighting each restoration, then right-clicking over them and choosing either "connect to mesial" or "distal neighbor." Then Highlight them all using control button. Then on the bottom "pop-up" pick "Connectors" make 'em how you want them , then merge 'em.. Quick easy fix and "it's a good day in the "connector neighborhood"
Nobody is more riddled with ADD,OCD, and feeble-mindedness than me, LOL. Like 2th said Exo wiki could stand to be updated. And it would be nice if they added some of the tricky fixes! Here's a quick screen Vid where I purposely didn't check the connectors in the DB project...

@LarryRDC if you know a trick to connect to mesial or distal neighbor using waxup/copy mill I'd love to hear it.

Please don't tell me it's possible from using the menu that rises from the tool bar in expert mode. Lol

Yep you are correct 2th, as I set the test video as anatomic crowns, not waxup/copy mill...I told you I was riddled ADD!!

I 50/50 Agree with you, except that Riley has come so far since his original post of his thread, that I'd hate for him to totally chuck it in at this point.

I don't remember exactly what I did, pretty sure I did the save mesh as stl and used it as a preop and morphed to that. Doing it that way I found actually does a better job than morphing to a wax up.
