Propagate Extents

[gibson.tim91884]

While trying out propogate extents from Steve's Blog (http://revitoped.blogspot.com/2006/01/propogate-changes-to-grid-lines.html), I get some weird (to me) behavior.

If I have a crop region in a view, and the 3D extents of the gridline are outside the crop region, then the propagate extents button does nothing. No dialog, just a silent failure.

If the 3D extents are inside the crop region, then the propagate extents works fine.

I also noticed that views with a crop region (smaller than the 3D extents, I think) don't show up in the propagate extents dialog.

Does anyone know if this is the correct behavior?

I see the same behavior as well. If the 3d extents of a grid lies outside a crop region Propagate Extents fails to launch. Bug? Intended? Not sure but it doesn't "work"... If you are careful to keep the 3D extents inside the crop region, change the 2D extents to be outside the crop region, Propagate Extents works as expected.

I am using a default template while trying this out. When i drag or change a datum level in East View, the Propagate Extends command highlights only the West View and not the North or South Views.
I do understand that it seems to be working logically, as far as the extension of the datum line is considered. But say if i have two levels very close to each other, and we normally break them, to see the text on both of them, then i would like to Propagate the same to all Views. Wouldn't this be possible, in this context?

[Steve_Stafford]

Revit will only offer similar views. Since North and South are viewing from opposite sides you get the "other" when you propogate extents from one. You have to do the same for East and West because they are 90 degress out of phase with North and South. Perhaps a little to literal of Revit?

Bringing this one back up, becuase im curious if the behavior is, in fact, intended. We have a LOT of drawings in a model where the crop region is MUCH smaller than the Grids 3d extents. (Tenant spaces in a mall). People are trying to use Prop. extents to set grids up on RCP's the same as they are on the Floor Plan, and its not launching...

Id love to know if there is something we can do about this, its costing us some time...

Three years and two months later, bumping my own post bumb again, LOL.

Two offices and 3 versions of Revit later, im still having the same trouble. Right now- at least- since we can now turn off crop regions without resetting the extents of them, it appears like we can grab the views, shut down the crop region, propogate the grid extents, and reactivate the crop region.

Otherwise, if the above mentioned conditions are true, the views dont show up in the PE list. Still wondering why that is the intended behavior. I sort of see why: if the extents of the propogating view are much farther out than those of the view to be propogated. But id rather do that intentionally and then drag the 2D extents (which all lock together) back to a respectable location, than have to OFFSET each individual grid head left or right for visibility (which you cant do en masse).

Thoughts?

Yeah, so is this is one of the more depressing threads I've read. I'm dealing with a huge project that uses lots of dependent views with multiple plans for each section. And with the convergence of new and several existing structures, each view has dozens of grid lines.

Propagate Extents is worthless in it's current form. And yet it is unsurprising the tool has made it this many versions with such asinine requirements to work (ie, all 3D extents must be within the crop region). They should at least revise the help file to specify these limitations.

[twiceroadsfool]

What version are you working in? My last post was prior to Revit 2011. Revit 2011 now allows you to Propogate Extents to views that have crop regions, and scope boxes assigned, and it works wonderfully.

I cannot get it to work. What am I doing wrong.

[m_r_meza]

I cannot get this function to work properly, but maybe I am not understanding what it should do. If I change the location of a HEAD of a grid line and then hit the propogate extents tool and go through which views I want it to transfer to, should it change that head location on all subsequent views? It seams to change the view settings, i.e. if grids are grayed out, the grids in other views get grayed out, but head locations don't change for me. Any suggestions are welcome.

[dznr27]

I figured this out. All grids must be in the 3D mode. All heads need to be adjusted so that when you pick a grid a little 3D apears versus a 2D. Also do not crop any of the views that you wish this function to work on, including the parent view. Some grid heads may need to be adjusted in the Z direction to be in the 3D mode.

It's absurd that this tool doesn't appear to be very useful for large projects with dependent views and cropped grid lines.

Add to wishlist?
