Need help cutting hole

[sjsl]

Trying in vain to cut holes in an elliptical ceiling i.e. coffers. Made ceiling but cannot use opening tool. Only choice I can think of is void masses.

any other ideas welcome and appreicated.

When creating an opening, you cannot sketch loops within other loops. The highlighted loop(s) are contained within another loop.

Voids would be the way in this case.

In the French web library there is a hole/dome family that goes in ceilings. I tried it and it work with elliptical ceiling. Go to French library/plafonds/niche de plafonds.

hope this helps.

an inplace void family should do the trick.

Remember, everything doesn’t have to be 3d modeled in Revit. You could always just use Detail lines to do the job. I find a lot of first time Revit users think that they have to model everything. The only thing that has to be 3d modeled is any exterior components because that will be shown on all your elevations.
The question that you have to ask your self is, will I be showing this to the client, is it quicker to model it or just 2d draft it. Let’s take a kitchen for example. Will my client see this in 3d (through a camera shot? Will I be doing any sections through it? Will I be doing any elevation(s) of it? If no to all these questions then why don’t I just draw it with 2d lines and label it as required. I know every project and firm is different but you really should ask this question before modeling something interior.
But for something like this Sbrown is right about creating an in-place family.

There’s my 2 cents for the day….

Well from my experience and going by the advice of others here, you really need to model as much as you can. Lines really jack up the file size if you have alot of repeating lines (exploded AutoCAD views are the worst). A model family in a project really only affects the file size by whatever the size of the family is, since the program only has to remember the different parameters for each instance of the family.

Plus the more you model, the less you have to draw in each view. Everything will show up correctly in all the views if it's modeled.

In my experience new Revit users (especially those who have known AutoCAD before) try to draw alot of things with lines, things like casework in plan, floor patterns, etc., and I'm like noooo you need to model it, it will be much easier later! ;)

As for the ceiling, is this just a ceiling that pops up higher that makes an elliptical shape, or does the ceiling actually have a curved surface? If the former, I usually just draw the lower part of the ceiling with the elliptical-shaped cutout, then draw another ceiling that's the inside higher part, and then draw a soffit/wall that connects the two. Doing it this way will make it show up correctly in all views, all elevations, all sections, etc.

Thanks for the input. I think I like the last idea the best.

Oooh yes. Model. It seems like longer in the short term but in the long term its brilliant. All i can say is for a new user it takes abit of getting used to, but once you get the hang of it....:)
