do not delete dimensions

do not delete dimensions

Sometimes when I change a family and reload it into the project I get the warning that Revit wants to delete my dimensions. Right now there is only one thing I can do, just delete them. Otherwise my family will not load.

 

Is it possible to just keep the dimensions and flag them in the corresponding views, mark them red or with a big exclamation mark connected to them?

 

I am getting tired of shifting to all of my views to find which dimensions have been deleted.

Yes. It would be nice if Revit were a little more intelligent about finding new elements to associate to. I have similar problems when dimensioning to floors, columns, etc. that generate "new" faces when I edit an element that it's joined to (and therefore break the dimensions). One particular project comes to mind that really annoyed me - I had a beam (representing a thickened slab) and I dimensioned to the bottom points, then every time I changed something (I think it was the Floor), I'd loose the beam's Dimension!

 

The first time I tried submitting it to support (that time it was a bunch of column dimensions that got lost whenever I edited the Floor above), the tech kept trying to say it was "user error"! :cara_de_decepción:

 

I understand that we don't want to go the way of AutoCAD and have a bunch of dimensions that are just floating around and not attached to anything, but when something is in the SAME EXACT PLACE, Revit should be able to figure out that it can just use the "new" element (even if internally it has a different face or edge identifier). It would be nice if we just got a bunch of warnings "Dimension was reassociated from [old ID] to [new ID]" instead of just "Dimension was deleted".

 

BTW, is your family in the same version of Revit as your model? We sometimes get odd behavior when upgrading.

Show view with deleted Dimensions after deletion warning.

Yes plz.

 

This is so annoying.

 

Just let us see wich one needs to be deleted and maybe we can change the referencpoints so we don't need to delet it.

I have the same problem when I open my file with linked files (which is 100% of the time with MEP) and it cannot find the linked file it deletes my dimensions without giving me a chance to relink my file, and now I have no ide whe dimension have been deleted.

Dimensions in Revit have a dual role. They show the location of an object but also define the location of that object. In most cases this is a blessing but if you want to dimension a repeating apartment the dimensioning can be repetitive. If you try to duplicate a dimensioned plan view by copy or adding the dimension to the apartment group you often get mixed results with dimensions finding different targets for different groups. We now solve this issue by making a detail group and adding detail lines that align with the walls witch are dimensioned and grouped. Such a group you can copy without a problem.

 

It would be much easier if you could disassociate dimensions so you can group copy them.

This is a HUGE pain for me, and I am sure others have experienced this problem. Revit has MANY idiosyncrasies, and this is one of them .

 

Dimensions, placed. Took a while to get it all looking right etc. You need to move something or edit an object. Say the slab line or some other object which usually lies over another object. BAM!, Dimensions disappears. because you referenced the modified object!

 

You have an inserted dwg file as an overlay, (still waiting on PDF support guys)... You have to update the reference. BAM! Dimensions disappear! Have to redo them! Why? Because the reference, or witness line rather, was attached to the object that was modified. Sometimes you can pick up on the losses, and redo the lost dims, but many times, the dims get wiped out places you weren't expecting.

 

Copy and paste dimension in other views. Some dimensions can't be copied because they, "couldn't find a reference"... Really? Can't Revit just find an object in the place you want to paste and link to that?

 

Revit should be SMARTER than this.

 

SOLUTION: If a dimension witness line lies over multiple objects. eg, Wall, Slab, Lines, etc, and the referenced object gets deleted or altered, make the existing  dimension pick up on the next available object underneath or over it! Make the dimension automatically re-reference the altered object!

 

Think about how much time would be saved if you didn't have to hunt down your lost dimensions and redo them?

I'm adding my vote but with the important caveat that I don't want Revit to default to the 'nearest' object or something like that. I want it so become 'orphaned' (just like tags can be). They could be included in the reconcile hosting dialog. Ideally combined with a "don't print unhosted tags and dimensions" option in the printing dialog.

Great idea, seawasp. Can't agree more.

I agree 100% and although REVIT error window notifies user that some dimensions will be deleted i think a smarter option would be to offer a new dimension option, where REVIT auto-calculates the new position/modification and offers the user to select that dimension string in lieu of any dimensions being deleted or reference dimensions being lost.

If you place dimensions to geometry that's with a linked model, you must have noticed that if the geometry is amended or replaced Revit will delete the dimension automatically when the link is reloaded (it gives an error message).

Whilst I understand why this happens, Revit does not do this with tags that lose their host, with them the user can click on the re-host icon and fix them.

This is inconsistent. Revit should take the same approach with dimensions.

So if a dimension can't find it's host, the user is given the opportunity to select a new one.

Agree. I am having this problem with my my project where the links cause regular issues with dimensions.

Great suggestion- this is really frustrating with linked files, which we use a lot for multi-family projects.

I think the solution should be to change the dimension colour to an error colour (orange or red? whatever the ini setting is) and make it non-printable. The option to re-host often fails when opening a file where the link has changed as you can't re-host a until the file is open (but can't open without resolving the problem). You could then work though these error dimensions in your own time. Also same should apply where there is a text override, why Revit assumes that the contractor should no longer confirm the dimension just because I have change the witness line is beyond me.

I'm happy with the way tag handle this, essentially the tag turns into a question mark, and then the user has to click on it and select a new host.

 

My only issue with this work flow is that the question mark can be hard to find on a complicated drawing - I would refer a little yellow warning triangle next to the dimension.

Yes or just if it becomes a coloured text. That would work well for the dimensions as well.

Maybe a combination of the tag (question mark/option to re-host) method, and a change in color? I also like the idea that non-hosted dimensions wouldn't print until they were resolved- perhaps this is a checkbox, like the option not to print unreferenced views?

Yes - all that sounds good.

 

I would like the ability to click the dim and then select the warning icon to rehost it as opposed to clicking on the ribbon rehost button as this would be slightly faster.

What would be really nice would be an option when a dimension cant find its host for the dimension automatically to re-host to an object if its in exactly the same place as the object it was originally hosted to.

 

We get issue with dimensions when users delete objects and replace them with something exactly (or almost exactly) the same.

 

One example of this is dimensions floor plans, some of the dimensions host to the floor, not the wall (the floor and wall line is in the same place) - the floors are then deleted and replaced causing the dimensions to delete.

 

If the dimensions could automatically re-host to the wall line that would save a lot of time.

I'm kind of ok with that one as when people use that process all of my floor, wall or ceiling (services) hosted families in my linked model lose their host. I sleep better knowing that this poor BIM process also causes pain to the perpetrator. It is a pain when you split a floor, wall or beam and all the hosted components (including dimensions) now belong to one half and not necessarily the one they are on.

Allow for keeping the dimensions that have become invalid, not just to delete them.

 

However, when this option is chosen, these should be overriden (maybe colour and by adding a non-removable prefix) so that they can be clearly identified for quicker correction.

 

Also, add the list of invalid dimensions to the Warnings list.
