This was a big issue for me on a current project and I wanted to make sure it was fixed before we start phase II In the 2016 version we created a script to change the color from blue to the color we wanted. The script was a huge time saver but even with that, it was 5 seconds per sheet every time we updated the view or the BOM.
This issue seems to be resolved in 2018. One thing to be sure to do (and not to do)
Do Not make the changes by unlocking the content and format.
In the Project Setup-->Ortho DWG Setting-->Setup Title Block
Click on the Annotate Tab then in the Ribbon Select "Tables"
Set AdskIso as the current table style
Select modify
Under cell styles, select the text style, height, color and angle for data, header and title (and any others you may use).
Set up your BOM table
Place BOM table on the sheet.
Select - "Return to project Setup"
Select OK
Now the set up will stay in place.
**Warning** If you make changes in to the font via unlocking the content and format, those changes will be overwritten when you update the view or BOM. All font changes need to be done in the AdskIso table.
I will also say, so far I have only tested this in a test project. I plan on trying out several things on an actual project soon. So if anyone tries this and it doesn't work, please post here.
Now, If Autodesk can figure out how to have the bolts in Ortho BOM display the actual number of bolts instead of bolt sets (like it does in the ISO BOM) then we may start to get somewhere with ortho creation in P3D.
