Problem wtih adjustable angle

[agnija.praskelevica]

Hello! 

I have a problem with adjustable angle. 

I made file with light and set all setups (work plane based and shared) to load in another family (generic family type)

Then I made my second family file (generic type) and host ref. line with adj. angle.

Then I try to load my lighting fixture family to generic family and host on plane. Than I pick a ref. line.

And then my light is uncontrolled rotate to 90 degrees and I can rotate back and host to ref.line with my adj.angle. 

Can anyone help with that? 

Thank you!

• When you are placing the light fixture in the generic, are you placing it on face or on work plane?
• When nested it needs to be hosted on the respective plane (it has 2, the base plane and a normal plane) not on the reference line... To do so you need use pick plane >> hover over the line till you highlight the desired plane

Apart from the above, it is not clear what type of light, where it will be hosted in the project, how will it be expected to rotate!!! from the image you posted it looks like a recessed can or similar and doesn't really look rotatable 

Post the family components to have a closer look

This light can be rotate above -15 and + 15 degree, like that:

And I add my lighting fixture family file with light and generic file without light.

Hello @agnija.praskelevica ,

When it comes to hosting on a reference line, your nested family has to be face-based. As far as I know, making it workplane based will not work.

Then as @RDAOU said, when nesting the family you have to :

- edit its workplane

- pick a plane and click OK

- then hover on a reference line and tab it to select which plane of the line you want the nested family to be hosted on

- adjust the position of the nested family on the line

It is still not working. 😞

Maybe my skills in Revit are too bad. 

I try adjustable angle already 3 months, and not result. 😞

Your nested family CAN be a workplane based like what you already have.  You just need to move the light to the Level/Origin reference plane.  Then the rest of hosting it on a reference plane of of reference line (not the reference line itself) has already been explained multiple times.

You've been at this for 3 months???  Wow.

Post your file and let us fix 'er up for you. Probably take a few minutes though. That okay?

If I try this method, then my light source rotate, like that, but angle is working.

As stated in my initial reply...the purpose or intent of what you are trying to so is not clear. The light family which you have placed therein, is an object (1 element) ie: it has no rotating part in it. This means rotating that spot light as is will not function similar to the CAD detail you have posted. 

1. If you want to have the light physically rotate as per your cad detail, you need to remodel it in Revit.
   • You will need to model the frame in one family and the core (spot) in a second family
   • Nest both into a lighting fixture
     1. the frame constrained to the reference plane parallel to the ground
     2. the core to a ref. line or a revolve which allow its rotation
2. If you only want to rotate the light source, you can do that without rotating the geometry of the light itself. Simply use the OOTB Tilt Angles (see GIF below)

Attached is a family for a rotating Spot light...it is based on the one you posted but not as detailed but I think you are capable enough to edit and Refine the Extrusions so that it looks like urs

It rotates Max. 15 degrees in all directions hence you will find 2 Angles ...See GIF BELOW

[agnija.praskelevica]

Yes! You are right, in that way rotate the light! Maybe we have misunderstanding, because I still learning. 

But it is possible this solution - If I rotate the core, then light source rotate too, example, if I have a only A angle from -15 to 15 degrees, then light source rotate in the same angle?

@agnija.praskelevica 

You can link the core rotation to that of the light source yes...However, the family attached measures angle from the Normal to the spot ie: the 15 degrees = 75 degrees if you need to control it via the Source Tilt parameter ... to do that

• Either change the parameter in the family to measure from horizonal plane instead of vertical
• Or in the host associate the Source Tilt angle with the Angle A ... ie: = 90 - Angle A

If you do not need the sport to rotate in a conically...then set Angle B to 0 always

Thank you! 🙂 This was really helpfull!
