    Drain with 3 AP

    Hi guys,
    I try to create a kind of drain with 3 adaptive points. Between the AP I have created reference Lines. On the reference lines are hosted 3 reference points (with normalized 0 or 1 to have them at the end of the line). Hosted on each of these RP are AP Profiles. Because I need a rotation parameter I have nested the profiles. The profiles are AP families with one Adaptive points, and RP hosted on the AP. The RP are connected with model lines

    Problem1: I cannot select 2 Profiles and generate a form
    Problem2: I cannot use a reporting parameter of the angle to drive the angle of the profile

    Attached are some pictures with description. In the onedrive link is the revit project

    One Drainage is without the rotation parameter in the profile: the volume creation works

    The other drainage has the profiles with rotation parameter and a correct angle but the form creation does not work in the family.

    Any tips how to continue?

    Thanks,
    Thomas

    I would suggest you only host a single profile at the midpoint of one of you path lines. Then create the swept geometry. It should split your mitered condition equally as you are attempting without adding additional parameters and constraints.

    If you want a drain that follows a series of points, in this way, do this:

    • create adaptive points 1, 2, 3...
    • create a reference line that goes from point to point.
    • host a point on a reference line,
    • host a generic model family, work-plane based, with the shape of the profile that you want, hosted on the new reference point.

    That is all. Then, in the project, click 1, 2, 3... and this will create a continuous gutter or drain, with the profile.

    Having said that, notice how many extra steps you have taken so far, that are not necessary and/or that actually make the family not usable:
    1) a "profile" that is also an adaptive family with an adaptive point, (not good)
    2) a "profile" that is hosted at every point (not necessary unless you need the profiles to rotate around the host point)
    3) an angular dimension to control the angle between two lines driven by adaptive points, (not possible)
    4) normalized curve parameter to keep a point at the end of a line, (not needed)

    Thanks Alfredo for your help! I'll try it asap
    btw: It's not for me, I just try to solve a problem from someone else in another forum The goal is to create something like this:

    Drain with 3 AP-15-06-_2019_14-13-03.png

    The profile is not perpendicular to the reference line, how can I change that?

    I get always an error when I want to create the form.

    As soon as I create a straight line it works:

    Drain with 3 AP-17-06-_2019_23-44-14.png

    but it breaks as soon as I place it in the project

    Creating the profile manually with model lines in the adaptive family - then I can create the form

    /e: Got it the mistake was to make the nested family "Always vertical" =)

    Profiles for extrusions in adaptive families work better if they are generic families, workplane based, not always vertical.
