remove the floor in the room DBX and use a ramp as the floor. Not exactly sure what your condition is though.

If i use a ramp, can I have the width at the bottom smaller/larger than the width at the top?  Example:  bottom width 5', top width 7'

Unless I am mistaken ramps are parallel so no to your question. You could use p solids and solid subtraction to create the floor.

Create a wedge shaped "Face" in cross section view and then sweep/extrude it about a center point.  This is not simple but with some calculation and experiment you can get what you are asking for.  Another way to do this would be with a Molding Profile assigned to an arc.

Yes

Yep.  This is what I would probably do as well.

IMO, the simplest method is to use a wedge shaped molding profile on a Molding Polyline.  It's really easy to adjust the radius of the Polyline as well as the width & height of the Molding Profile.

For a simple shape yes, but for something with no radius or a more complex floor shape...not so much.

Here's a stepped floor using a Molding Profile on a Polyline.

Isn't that what a ramp is? Ramps are not parallel.

As I understand it, the OP was referring to the PLAN VIEW shape being a non-rectangular shape.

Yes Michael that is what I assumed as well. As far as I know, we cannot "flair" the ramp, instead it has parallel sides.

Yep, that's why I would use the Molding Polyline.  I agree that to flare the sides you need to use an arc - but I think that for a theater, amphitheater, etc it would commonly be an arc anyway.

I though he was talking section view and a garage would most likely have parallel sides

But he wasn't talking about a garage.  He specifically stated a "Music Venue".

A music venue can be square can't it

It could but much more commonly it's like an amphitheater.  This is true for most entertainment venues facing a stage.

Guys I thank you for the help.  I and wanting to design a venue like a concert hall that would have a sloped floor for the audience.  I have played around with p.solids and created ramp with a wider width at the top and a narrower width at the bottom, was not too easy for me.  I already designed the facility without the sloped floor and now I need to figure out how to put one in without starting over.  I should get it right in about a year, lol

Post the plan jberd, pretty sure there will be more help to come if you do.

I would use a roof plane - very straight forward and controllable.

You can shape it and slope it any way you want.

Copy it to a blank plan and convert it to symbol and copy back into the original plan.

By making a symbol of it, it won't be treated as a roof plane and thus it won't cut walls, etc.

Only takes a couple of minutes to build it.

Another option would be to build a sloped terrain,  build a sidewalk and then turn it into a symbol.

 

The roof plane is probably the best solution.  I do not like converting to symbols because the editing is lost.....  but not sure if there is much choice.....  the roof does not need to be turned into a symbol if there will not be a problem with cutting walls......

Scott,

 A bit hard to control exact slope using a terrain. ie, making it 10deg slope (2 1/8 in 12)

 

And I think having roofs inside rooms with other ceilings and roofs above is asking for trouble

I don't think Chief was developed to design Concert venue's even though I'm sure someone could do it. I would use some other program that does commercial better.

Just throwing this in for some feedback because I don't have the skill level to compete with all you guys. But lots of ideas here.

 

What are the possibilities of using a sloped ceiling plane and an extra floor? I think it could be framed structurally as a floor and not have the potential drawbacks of a roof plane.

 

If the OP intends to build a wood structure I think this could work.

      I wonder why my second floor loft flooring is sticking through the roof and can be seen on the outside of the building?

      I accidentally deleted the floor surface from my layout of a building. It appears that the top floor surface is missing leaving the subfloor. I don't know how to add a new floor surface to the subfloor (walls are built and floor plan is otherwise complete).

      I have designed a pergola and a deck. I cannot get the terrian to show right. It needs to be zero of level at back of deck by pool deck and slowly slope down to a bayou. it needs to be 36" to grade at edge of outer deck Then a stair going down to the end of stair which is around 5 fr lower that top of deck. I have not did much terrian and would appreciate your help. This is just a remodeling and adding a deck from the pool. 
       
      Thank  you,

      I've been an active user of Chief Architect for about 15 years now. I am currently using the X11 and have an SSA.  In all of these years using the software I have been frustrated with a couple things in the electrical area. First was the terrible placement of electrical connectors, they were never placed in a way that was visually appealing. I was always wasting time adjusting the lines after placement just to make them look nice on the plan.  Thank you Chief, in X11 the lines now, most of the time, place in a visually acceptable manner. A great time saver when doing the electrical! 
       
      The second, frustrating issue is the lack of programming to address the floor-to-floor light switching. I have over the years visited ChiefTalk hoping someone had a good solution to address this issue. I have never liked any of the proposed solutions, namely placing the correct 3-way or 4-way switch on each floor then placing cad arcs or splines to represent the electrical connector. I felt it to be a time waster and it just did not feel right using a cad line instead of an electrical connector. 
       
      So, in response to my frustration with floor-to-floor switching I came up with an idea and ran with it. I created two floor-to-floor connector symbols. The symbols are identical except that one is designated as being switched and the other is not switched.  Both are, in plan view, a 2" circle, defined as an electrical item, In 3D they are a 2" clear glass sphere and attach to the ceiling, being virtually invisible in a 3D rendering. When I am doing a floor-to-floor switch connection I place the switched symbol in the stair well then connect the switch to the symbol. The switch then automatically changes to a 3-way. I have a set of text labels that I then place over the switched symbol to indicate the usage of the switch, i.e. "To light above", etc. I have attached an X11 library containing the two floor-to-floor symbols, (switched and not switched), and the text labels I use.
       
      I hope these will save you a bit of time. Enjoy!

      Chief Architect has been a blessing to me in the last year that I have been utilizing the software. However, I work in the United States Virgin Islands St. Thomas,  where there are seldom flat land to build on. Therefore, there is always a slope in the land and I am having a hard time landscaping. Are there any techniques or tips anyone can offer.
