I hope hjacobs will place this new tutorial under TUTORIALS and give me some new points...
Perhaps after some modifications of the tutorial?!., Perhaps correcting some English expressions?!.,
The tutorial is about how to make a sloping rounded roof by using
Modelling > Create > Solid > Sweep
because you can not use eg Roof by Extrusion to make this sloping rounded roof

Hey Mr GG,
Had a look at your tutorial, you realise this roof could have been easily created using the roof by extrusion method rather than using an in-place family??

Well I tried to use the roof by extrusion method
but as far as I experienced
you cannot do a rounded roof that is sloping.
Because you can not use a workplane that is sloping to draw the contour of the roof.
That is the problem that struck me.
I did not succed in Picking a sloping plane nor did I succed in picking a line in a sloping plane.
Revit just ignored them!
Perhaps you will succed but I did not.
And a not sloping roof made with Roof by extrusion
you can not rotate to give it a slope as far as I know.
Well, perhaps I am wrong
but I do not believe that just now!!!!
Show me an example and I will believe you...

Here is an image of the two ways
I tried to make a rounded sloping roof..
No one worked...
Perhaps there is some better way???

Mr GG et all:
This was very helpful instruction on a subject that was, for me, immediate in nature. I can provide an image of what a sloping rounded (eliptical) roof -does- look like as an extruded solid and void. I am glad to see other options.

I have also tried using a sloping reference plane
but Revit does not permit me to pick it
then I am trying to do a roof by extrusion.
I cannot imagine any more alternatives
but I hope you Mr Spot has an alternative
but perhaps you are mistaken....
So I hope for an example
showing how to do a rounded sloping roof
using Roof by extrusion.
OK! There is a way. You can do it in a .rfa-file
and load it as a component
because then you can rotatate the component
making the roof slope.
But I think my way is better
with Modelling > Create making an inplace-family
with Solid > Sweep

HALLO! Mr Spot!
You told me:
this roof could have been easily created using the roof by extrusion method rather than using an in-place family.
BUT THAT IS INCORRECT I BELIEVE! Can you show me an example I will believe you.
You can not make a sloping roof wtth Roof by extrusion
because Revit do not let you choose a work plane that is sloping. It have to be perpendicular or horisontally.
I have tried to pick a slooping Reference Plane, a sloping face of an extrusion and a sloping line in the plane of the extrusion - but Revit does not permit you to pick something sloping. Have a look at the image of my tries. The picture is named Roof_examples.jpg and you can find it a bit higher up on this side. PERHAPS YOU HAVE A WORKAROUND???
I suggested - see one of my comments - to do a Roof by extrusion in a .rfa-file and then rotate it in the .rvt-file but I WAS INCORRECT in that matter. You cannot do Roof by extrusions in a .rvt-file and you can not either do a Solid > Extrusion in it and then rotate it. So that does not work either!
So I still believe my way is the only possible way - doing an inplace.-family - to get this sloping rounded roof. I hope you can show me an example or admit that you were incorrect because I want to have my tutorial published if it is correct.

I added your tutorial to the tutorials page, but in light of Steve's post, I changed it slightly to note that your method is not the only way to accomplish your goal.

Thanks a lot hjacobs
for placing my tutorial on making a rounded sloping roof in the tutorial section.
I can see that you have made it easier to take part of the tutorial
through dividing it into parts. Thatīs good!
But I think you have made a slight mistake - or two I think - by writing this in your introduction:
In Revit there are two ways to accomplish this. Use a roof by extrusion in combination with voids, or an in-place roof family. This tutorial explores the latter method.
The LATTER method is not explored by this tutorial. It is the FIRST one yiu mentioned that is explored by this method! OK!?.,
You also write that there are two ways to accomplish this. But I do not still believe in that. I have tried to pick a sloping plane,line or ref.plane to make the profile for a Roof by extrusion.
BUT REVIT DOES NOT LET ME PICK SOMETHING SLOPING IN THIS CASE!!!!
Perhaps Revit let YOU - NOT ME -. pick something sloping for a Roof by extrusion but I do not believe in that before I can have an example. I have asked Mr Spot for an example because he was the first to tell me I was a bit incorrect. Steve and AUGI I do not believe they can pick something sloping either in this case,.,.. Perhaps I am wrong... I just want to see an example of the opposite...
And a little more correction in your introcuction ... You telll that VOIDS are needed in "my method". NO!!! the VOID is just there to cut out a piece of the roof. If you do not want to cut out a piece of the roof you do not need to use Void. The round sloping roof is ONLY made with SOLID > SWEEP.

Good day, and as I am new to this forum (not forums ingeneral) I will keep my conments to a minimum.
Mr.GG - I have appreciated many of ur posts and images greatly, but I will have to say...are are a hair mistaken. If you real your post carefully thesecond method is the one you origionally discribed using an "In-place family" model-solid-sweep as opposed to a roof extrusion. I do however agree very much with what you are sayingabout not being able to choose a sloping plane to create an extruded roof on, I havn't been ablt to do so either. That said, the "Other" option does work,but in my opinion does require a bit more thgouth and work. What they (from steves example) are basicall doing is creating a sloping BOX that can encompass the entire barrel, than using a reference plan set at a "facial Level" making a void that dictates the thickness/shape of the barrel.
In reading this I am not entirelysure this is any clearer than the origional, but it is my attempt explaining what is actually going on, US BIM guys gotta stick together until everyone else out there gets their heads on straight and realises that this is Indeed the ONLY way to go.
Thanks again for all your help (everyone) thru the forums and I lookk forward to being a muchmore active forum member and contributer.
PS> Keep an Eye open for my First Gallery Submission...comming soon has an integrated barrel/single slope roof (done with a Create in place family)
Ciao,
DeastyBoy
