    Angular Parametrics

    I'm trying to make a family to represent an occupancy sensor. It'll only be shown in plan view.

    The attached image shows what the boss wants it to look like. I'm trying to make the arrow parametric so that I can choose the angle (it represents the direction the sensor faces).

    I'd prefer to be able to pick a glyph of some sort and manually change this angle but I'll type it if I need to.

    I've tried everything I can think of. But although the reference lines seem to change ok when I update the angle, as soon as I lock lines to the reference lines and try to flex it, it breaks.

    I've tried both symbolic lines (what I think I should be using) and model lines.

    Host the arrow head reference lines to the arrow body reference line. Host the lines to each individual reference line.

    Try this one. ( Revit 2015 )

    I simplified it. Grouped Ref Lines , named the Group Arrow.

    Deleted your dimensions and parameters, then placed an angular dimension. Flexes fine.

    Nope. Change the angle to 45, then to 0, then to 45. It breaks. I don't think the group can be locked to the pivot point in this way.

    Yup. This is correct, and with the correct shape (ellipse instead of circle).

    Also, attached is the version I did last night, and an image showing the family in all directions. I made it as a Lighting Device family, with a Generic Annotation nested in, that scales up and down with the scale of the view. The family posted in the original post of this thread was not going to scale with the view because it was just a model category with no annotation. The rotation of the arrow does not need more than one parameter and one reference line. The lines are simply hosted on the line (including the little arrow lines).

    Thanks Alfredo. I have a couple questions about this family.
    1. I don't see any reference lines in there. Show how did you lock the lines to the right angle?
    2. How did you lock the arrow head lines to the right angle, length and location along arrow body?
    3. I placed the family in my project and it worked great! Until I printed that is. Even though the arrow is masked by the Mask Ellipse in Revit, the mask does NOT hide the arrow on the print.

    EDIT: Disregard #1 & #2. I previously missed your comment about hosting the line on the arrow body line.

    Hmm... I was not expecting that. I saw it working fine on the screen, but I did not print any view. I don't have an answer for this at this moment.

    It's not like the arrow needs to be inside the ellipse. Could just drag the line out of the ellipse and the gap will be negligible all around. Unless scaling would interfere with that.

    After all the time spent on this--wouldn't a Tag w/ leader work just as well?. Tag by Category or Multi-Category Tag? Put info / Mark inside Motion Sensor Family? Or nest an annotation family in the Motion Sensor Family?

    Made a quick GM Tag, Oval shaped w/ leader.

    Created quick GM for Motion Sensor, use Mark of MS ( or OS for Occupancy Sensor, etc.)

    Done. Rinse. Repeat.
