How to create multiple level lines in Revit Family?

[tsong]

I am creating families in Revit 2008, sometime, I need to create a second level line, does anyone know how to do it?

Thanks

Have you tried using reference planes instead? You can set the dimension between a level and the intermediate reference plane; this can be either fixed or parametrically changed. This quantity can be added as a new parameter to your 'family types' field. Let me know how that goes! Or click on the dimension string that you've just created and apply a label to it which will automatically show in the 'family types' dialog.

thank you for your answer, actually I was trying to make a downspout family.Please look at the attached file, you will know my problem. When I open the 1st level, i see everything of the whole downspout, (which I don't want, I just want to see a simple circle - the cut section of the downspout). I was thinking if I can create several levels in family, maybe I could solve this problem?

Thanks

1. Select the downspout geometry and modify the visibility settings, turning off visibility in plan and when cut in plan.

2. In the plan view, draw a circle using symbolic lines.
