Delete a lavel and missing objects

[Anonymous]

Hi, I Need to delete a level and missing lots of objects. How could I know which elements have been attached to a Level ? Thanks for help

Move level way up or down so you will see what move along with it.  Host them to another level if you want to keep them.

Another way is NOT deleting the level, set it to not structural / not building story, and put it in a invisible workset.

When you select an object, you will see the level that it is associated with in the properties -

Hi

Deleting level is a tedious process to make sure you are not deleting elements attached to it.

A. If the project is small then in 3d view, you can manually select elements one by one or by category and change the 

base level ( level you want to delete ) to new level ( the one you want to keep )

B. Keeping walls, curtain walls, columns,  unconnected helps the model to move levels without any errors. 

  ( cause they need base and top constraints )

If the project is big, then create a plan view for that level,

so most of the elements visible would be connected/ constrain to that level,

and then rehost, change the base constrains of all those elements to new desired levels.

General elements which are level based

1. Walls ( base and top level )

2. Curtain walls ( base and top level )

3. Floors ( only base level )

4. Roof ( only base level )

5. Mass

6. Column ( base and top level )

you can schedule these categories and change the base constraints in one go as well...

C. Deleting levels will delete anything which is associated to that like

1. floor plans

2. area plans

3. RCP

4. Structural plan

5. dependent views, plans

Best of luck

Cheers!

All good suggestions, but I'd like to back up here an ask the question: Why the heck are you needing to delete a level; especially one that is host to a bunch of elements?

Does it really matter why?

Maybe it's the thirteenth floor. Maybe it was made in error. Maybe it's for budgetary reasons.

No, I was thinking maybe there is something that shows what has been attached to a level at one shot like "reveal constraints" button. Thank you for all responds,

[loboarch]

You could make a multi-category schedule and apply a filter to it to see the elements attached to a level.

Thank you for asking @RobDraw.

If @Anonymous was deleting the level to mitigate another issue, it might matter if there was another solution.

It reminded me of something I did when I was first learning Revit.

Live and learn.

Does that help explain myself, Rob?

Thinking along the same lines as @loboarch...what about creating a view Filter (or two) to identify everything hosted to a level?

Hi..

There are elements which may not be constraint hard and fast constraint to Level but might get affected once level is deleted.

Consider for example Level 2 we are deleting..

1. Ramp for example : base constraint Ground and upper constraint Level 2.. the moment level 2 is deleted, the ramp will collapse..

2. Stairs for example : base level ( Ground ), top level ( Level 1 ), and multistory level ( level 2 ), the moment level 2 is deleted.. this stair will get affected..

3. Similarly for all 3d Elements, Walls, windows, inplace component, column, beams, roof, ceiling, floor, railing, ramp, stairs, model group...will get affected and there are no warnings of exacting whats getting deleted.. may be just the number of elements revit might mention which are getting deleted.

There is no short cut to fix or swap levels in one go..

one can filter only one category at a time with default schedules available in revit ( ex only walls, only furniture, only plumbing ) constraint to one level..

For Revit experts, there are many ways to fix it, like custom category to filters, dynamo etc..but it will be more about using experience than one particular method. some hit and trials and lots of cross checking..

Cheers!

That would only show the Level Constraint, not Host.  For example, the door below belonged to Level 2, but when Level 2 got deleted, the door remained and now married to Level 1.

[barthbradley]

Yep.

Interesting and thought provoking thread. I like it. A fun exchange.
