We just made the switch to Cadworx 2013, I import some legacy specs created in cadworx 2012. I have three different size ranges of pipe that are showing RED and hovering over gives me... "component data file not defined"

I have three other pipe size ranges that import without problem...... I am perplexed ?

size ranges in question are:

.75"-1" = sch 160
1.5" = sch 80
2"-4" = sch 80


ones that work are:
.5" = sch xxs
6"-10" = sch 40
12"-24" = sch (calc)

You'd want to import the extra data files associated with those legacy specs into your catalog. Out of the box, CADWorx does not have Sch.80 and Sch.160 (amongst others). Open your company catalog, and then choose "import by spec" on the Legacy Catalog Data ribbon tab; it will read everything that is needed for your spec, analyze what is missing and do the import for you.
