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.

Hello Joseph,
You wrote "Try Objective to make it happen with the split tool; fast."
I went to the Objective site and looked at the split tool and from
what I can tell the split tool just rotates an element about a given axis.
This is not really the issue with raking moldings. Does the split tool
reshape a contour so that it can be used as a raking molding that
correctly miters with an eave molding ?
Thank you,

Using the construction method for drawing the profile
of a raking molding described in Architectural Graphic Standards
classical orders and detail. It worked out quite well. see attached.

Hi Peter,

What you're describing is the rotate tool, i.e. rotating about a selected axis. The Split tool splits the selected object(s) across a line you specify. These tools work well together to produce complex shapes that don't rely on SEO's or cutting planes. You can see how the split tool can be used on profiles in the example clip for creating custom profiles.

I can't fully reply to the problem you're trying to solve without fully understanding the end result you're looking for. I've attached an image which may be what you're after - if it is, I'll explain how I made it.

Hello Ralph,
Thank you for posting on this thread.
As to my problem, if you look at my post of October 19 2007
on this thread, you will see that I have solved my problem
as posed in my post of January 31 2006, also on this thread.
Joseph Harouni suggested, or I thought he suggested,
that Objective could reshape the cross section of an eave molding
to make a raking molding that would correctly miter with the eave molding.
I cannot tell from looking at the description of what Objective can do
whether this reshaping is possible using Objective or not.
Thank you,

I'm not sure if this is the method Joseph was suggesting, but you can make the connecting profile really quickly by the following steps (see attached image):
  • 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.
This could be added as an automatic feature of OBJECTiVE if enough people want it - anyone care to comment on whether this is a common problem?

Hello Ralph,
Isn't your step #2 doing exactly what I pictured in condition #1
in my image titled "eave and rake molding.jpg" in my post of
January 31 2006 ? If it is then what I said about condition #1
holds for what you are suggesting and is not a classically correct detail.
If it is not then please explain further what you are suggesting.
Please show me what the eave and rake and the miter look like.
Thank you,

Hi Peter,

What I've done would only match condition 1 if I hadn't rotated the eaves molding back by the angle of the raked molding. What I'm doing is placing my viewpoint in the same plane as the roof, i.e. I can see what the connecting profile looks like by looking along the line of the raking molding.

Peter,

I've elevated the raking molding and eaves, hopefully to clarify further. Was this what you meant?

BTW - I just realised why you think this might match your condition 1. My step 2 is only a temporary construct to generate the required profile. The eaves molding in the completed model is still upright, i.e. not rotated. Make sense?

Hello Ralph,
My eyes must be playing tricks on me because 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 ?
When you say "What I'm doing is placing my viewpoint
in the same plane as the roof"
does this mean that Objective can make
a section/elevation that is not laying in a vertical plane
but can be rotated about the X or Y axis ?
Thanks,
Peter Devlin
