All lines with a Revit MODEL pattern can be aligned, while drafting patterns only allow the outside edges of the pattern to be aligned. Not for drafting patterns.
Pattern - as it is named in the Project Browser are not associated with Filled Regions or Fill Patterns but instead are Revit (Pattern Component Families) that use either the Curtain Panel Pattern Based.rft, or the Generic Model Pattern Based.rft Family template. When either family is loaded into a project with it is several builtIn types. Note: Pattern category in the project browser is only included if a Pattern family is loaded.
Filled Regions contain Fill Patterns and the names do not necessarily correlate to each other.
Fill Patterns (Drafting or Model) (Basic or Custom) are nested in Filled Regions and Materials and the names do not necessarily correlate to each other.
Revit .pat file can be found here, C:\Program Files\Autodesk\Revit 202X\Data\revit.pat . Inside the .pat file (really a text file, that may be opened with Notepad) you will find a commentary on the formatting of the file and the patterns. I recommend you read this entire commentary before editing anything. Also, be sure to creat a backup and copy not overwrite the file. In the Header of each pattern will be one of the following type directives, ;%TYPE=DRAFTING or ;%TYPE=MODEL. If neither directive is present, Revit assumes that it is a drafting pattern. Here is an example of each:
*Aluminum, Aluminum (cut)
;%TYPE=DRAFTING
45, 0, 0, 0, 0.25
45, 0.0625, 0, 0.25, 0.25
45, -0.0625, 0, 0.25, 0.25
*Block 8x16, 8 x 16 blocks running bond
;%TYPE=MODEL
0, 0, 0, 0, 8
90, 0, 0, 8, 8, 8, -8
To have the same pattern (convert or copy), one can copy the pattern and change the TYPE as required.
