Linetypes in CAD lost during import

The reason we would like PDF in there is for our Site Plans. We do those in Autocad because the line types are richer (fence line type, gas line, etc.) and when you bring them into Revit, you lose them.

I've tried doing the repeating detail family for fences (an arraying "X" symbol), etc. but it doesn't look that great and doesn't behave very well at corners and intersections.

Revit could up their linetypes to do more than just dash, dot, solid.

I use curtain walls and custom panels with nested generic annotation for the X - X fence symbol. It works great.

I haven't heard that one before - we'll have to try it. Thanks for the tip!

Hi @glnnbw

Thanks for posting on the forum!

Revit handles Line Types a lot differently than AutoCAD

In CAD applications, line-types determine the particular dash-dot sequence, the relative lengths of dashes and blank spaces, and the characteristics of any included text or shapes in lines.
In Revit, these properties are defined as line patterns, which are specified in the object styles assigned to element categories. These patterns can be overridden for a selected element in a specific view.

You can create a new Line Pattern under Manage tab » Additional Settings and select Line Patterns
See HERE for assigning a line style to your line pattern
See pages 2 - 6 HERE for more information on Revit line weights ( a few settings that need to made in Revit before importing CAD)

That a great tutorial on line types and styles, but the original subject concerns the lack of linetypes than can possess characters, not just dashes and dots, such as an "X" or "GAS" for fences or utilities. This thread will be answered when there is a feature added to Revit that allows linetypes with characters, IMO.

Allow me to suggest Line-based details with nested generic annotations for complex linestyles in Revit.

We've done line based detail families with nested symbols that array and they are OK, but when you get into corner situations, the symbols don't spaces out very well, you end up fighting them. I will have to try the curtain wall one since curtain walls have better spacing options.
