Openings in the floor

[alexsasu]

I cut an opening in a floor. How do I modify my opening, or remove it? If I try to modify the floor, revit is only showing me the original linework of the floor, not the linework of the opening!

Move your cursor over the opening profile untill it highlights blue (or Tab to cycle through selections) then select it, then select edit profile on Modify/Tab, opening profile turns pink, then make edits.
To delete, hover over profile, select , delete.

thx a lot...but it doesn't appear with blue,i tried. It only shows me the floor,not the opening profile. I have activated all the model categories in visibility, I tried to change the discipline of the view,but nothing works,like someone stole my opening!:banghead:. Merci beaucoup!

When you Tab to cycle through, pay close attention to the status bar on your bottom left corner of the screen. It might not be highlighting it but you might be able to tell if its being selected because it will tell you there what is being selected.

If not make sure you are in the right phase. or even make sure that the hole you created was a shaft or opening vs being a hole in the slab itself (try editing the slab)

Initially i've created an opening in the floor,but then i thought of simply redefine the boundaries of the floor....so when i redraw the sketch of the floor,with pink lines it looks good. Then when i finish, the contour of the floor follows the shape of my old-missing-long-gone-forever-lost opening....anyway, thank you for help!

Personally, I prefer simply editing my slab to include the opening (as opposed to using the opening or void/shaft tool)

The void/shaft tool has it's place (such as a lift core, or mechanical opening that MUST match level to level)
If it is a local opening, or an opening that only occurs in one level, I prefer to just edit my slab.
If you place a smaller border within the extents of your outer slab edge border it will simply create a void in this place.
In many ways, if you are creating a fall in your slab this is a MUCH better option, as it gives you points which you can modify in your slab profile to set your fall at those corners. Also from a structural perspective, most of the cut outs done in slabs are for wet area set downs, whereby another slab is then placed into that void area 25 to 50mm lower than the main slab.

In reality most of these set downs have a 'fold' where the lower slab will overlap the upper slab for structural integrity. Furthermore, if you use a void/shaft you cant put anything else in the space, including walls/beams/set down slabs etc etc.

At the same time the opposite can be true for this, sometimes you will have a void midway through a slab fall length. An opening in the sketch here forces you to setting heights at the void corners

But I would agree openings are managed most easily within the slab sketch first, secondly with shaft openings for multi floor openings. I would normally avoid using "by face" or "vertical" because it means trying to select the opening in the model by tabbing through the selection

Another workflow though is a specific family to cut openings. Up until 2011 you had to have the family floor hosted to cut the floor, but with 2012 you can have a face hosted family which will cut floors and beams. I havent used this on a project yet, but plan to try it once up and running with 2012

Good point Ben, as a personal preference, I would still rather input the heights at the void even if it were midway, usually this is known or can easily be worked out by knowing that the fall is 1 in 20 or 30mm overall etc etc...

I just find that it gives neater falls, when you go inserting points I find its quite hard to control the fall lines automatically generated (when you turn on the active component to see hidden slab edges) hope that makes sense...

Revit seems to treat a "slab sketch" void as a slab edge and produces nice straight lines to your fall points, where as adding in a point will sometimes produce strange results falling to other points and confusing the drawing a little bit, the 3d and section result is the same but it can end up with making the drawing a little messy if you plan on using those hidden fall lines in your documentation, at least that has been my experience.

Small points really but these are the minor differences produced with the different methods.

I am yet to try revit 2012 at all....reluctant to install it at this point as we haven't been using revit a whole lot in recent times...

Its worth the update for the new visualisation features alone, particularly the ghosting which makes modelling in 3D a lot better

Has anyone had any movement on this issue?

I am experiencing the exact same issue. This is also the same issue. Everything is visible in visibility graphics, phasing, workset, etc... I don't get any sketch lines.
I have a 3D view aligned to the floor plan, and can't see/select the opening, yet it exists....

I created a new project, and this doesn't happen. I have noticed that the opening cannot be overidden by category... Very odd...


*EDIT*
Okay, I have resolved my issue. I wasn't sketching the opening on the same workset as the floor..... very odd behaviour...
