Sloping Profiler

[Scott Bulmer]

I seem to have forgotten how to make a sloping profile. Can someone please advise me before I kill myself.
Thanks, as usual.

...it looks like in the part of your image labeled 3D the eave molding has a level top and is not rotated. Does this mean that after you have created the rake profile by viewing the miter cut edge at the angle of the roof pitch you rotate the eave molding back to level ?

Yes, that's right. In fact, I just used a copy of the eaves molding to rotate and then deleted it when finished. The eaves stayed on the level. It's really quick and easy to produce the raked profile this way.

Hello Ralph,
I am impressed. Thank you for explaining how to generate
the rake profile. It is easier than the projection method.

Does Objective rotate and split any element including AC tool
elements as well as objects ?

Thank you,

No - standard ArchiCAD elements (e.g. wall, slab, etc) lack the internal data structures to support these operations. Even rotatable elements like roofs and beams can't really be freely orientated in 3D because they can't ever be tilted to the vertical.

We're close to releasing a (free) update which will make it easy to construct objects from element selections which can be rotated and split - just striving to make this as seamless for the user as possible.

Thank you Ralph. It has been great talking to you.

In ArchiCAD 15, the Shell Tool can now handle such situations:

• 1) Use the Split tool to cut the connecting edge of the molding on the level
  2) Use the Rotate tool to tilt the profile back by the angle of the connecting molding.
  3) Place a section/elevation looking at the exposed end of the molding.
  4) What you see in the section is what the profile of the level molding will look like along the path of the molding on the incline. You can get a Fill to make a new profile from this by copy/pasting it to the floor plan.

Ralph,

I'm trying to create a rake molding to match my eave molding by your instructions. Where are you doing these operations? From this post it seems like there's a plan view and a section view? I've created the eave with a complex profile as a beam. My problem is you can't split a beam at an angle, correct? Please help!

Thank you.

If so, you are right - ArchiCAD has no tools to do this. I created, split, and rotated the object with OBJECTiVE, an ArchiCAD add-on.

Ah - gotcha. For $300.00 I might have to try Peter's way.....

I finally got around to experimenting with complex profiles

Using the construction method for drawing the profile

classical orders and detail. It worked out quite well. see attached.

Peter,

A couple questions on your method.

1. I assume you are using a beam for the profiles?

2. How are you doing the SEO's for the plumb miter cut? Are you using hidden elements to cut the edge of the beams? I try to do an intersect command on them and all hell breaks loose.

Hello Steven,
As stated in the graphic, the rake molding and the eave molding
are complex profile beams.
The SEOs are done with two slabs as hidden operators,
one for each molding to create the mitered end.
BTW the image is a .jpg and if you click anywhere in the image
it will open in a new browser window and can be dragged and dropped
on to the desk top and can be opened with Preview and is large enough
to see clearly and the text is readable.
