Profile to follow slope of roof

4hotshoes
Advisor
Can I use the same complex profile for a roof eave and rake? I want it to look the same with the detailed fascia and soffit wrapping and joining at the peak. I pretty sure I can do the eave with the fascia perpendicular to the roof plain. But it is not clear how to get it to wrap the corner and follow up the slope. I know that I can thicken the roof and set the ends, but I want to add detail to the profile. Is there a video for this? Can it be done? I am still new to AC. Thanks

If you model it all as a Complex Profile, I figure you should be able to use the beam tool then change the rotation and slope of the segments as required after drawing it in plan. ArchiCAD will finish all your connections then.

The annoying thing is that there is no way to make it associative, so any changes to the roof size need to be reflected onto the fascias.

Railings can be associative.
And railings can use custom profile rails.
And also they can be angled so they are vertical or perpendicular to the roof plane.
And they can continue around corners.

I am not saying this will be a perfect solution, but it might be one worth exploring.

Hm, I had assumed railings would not work in this case due to how it handles connections.

EDIT: After a quick play around, I cannot figure out how to get the connections to clean up nicely and end up getting the twisted kinks that I had figured would happen... It might work if there is a way to get the entire railing to align perpendicular to the reference line, rather than just the posts.

It will certainly work on the gable alone but I am not sure about turning the corner to then go flat along the eave.

I kind of got it working with a railing. With zero length direct connections, deleting the kinks cleans up the connections nicely.

If you are wanting it to be associative along gable ends, you will need to use single pitch roofs as you cannot associate with the ridge for some reason, while you can associate with every other node... If you do not mind fixing the ridge point each change then there is no issue with using a multiplane for gables.

One flaw in the railing tool is that it would seem that you cannot make an enclosed railing, so you will have the add an extra node of the edges in order to get it to appear continuous.

I was just playing with it myself and discovered the gable ridge problem too.

I even managed to get the transition at the corner when the side profile remains vertical.

The enclosed railing (finishing where you start) is a known problem and hopefully one that will get fixed.

For those following along.
It seems to work best if you use a profile with the origin on the outside of the profile (for testing I just used the stair nosing profile).

Use the profile width as the offset for the railing.
This will move it out from under the roof.

Set the rail connection to a 'Direct Connection' and use the profile width for extension 1 length.

You may need to do this for extension 2 length depending whether the railing was drawn clockwise or anti-clockwise.
The direction of the profile (which side of the origin it is on) will determine which direction you have to draw the railing (I think - I am still testing all of this).
