Scope Box Visibility

Scope Boxes are a very useful tool to keep extents of views uniform across the project. There are a couple of ways to control their visibility. The obvious method is to utilise the Visibility Graphics Overrides to turn them on or off in views, but this method will control all of the Scope boxes together.

If you would like to control the visibility of Scope Boxes individually and pre-determine the views in which they will appear, this can be controlled in their Instance Properties.

When a Scope Box is selected, in their Instance Properties there is a ‘Views Visible’ parameter. 

If this is selected it will bring up the ‘Scope Box Views Visible’ dialog box, where you can see which views the scope boxes are automatically visible and you have the ability to override their default settings to make them visible or Invisible specifically in each model view.

Grid Design Option

When you have Grids in your Project, the last thing you want anybody to do is accidentally move them. There are a few ways of locking these away so that they are protected from accidental relocation. You could use worksets or pinning the elements, but a useful Revit feature is using the Design Options.

You don’t need an elaborate naming convention, just create a new Option Set and Option and name them ‘Grids’.

When you go back to your model add the Grids to the Grid Option and they will be secured away. 

The Grids will still be visible but to access them users have to make a conscious choice to activate the Option to make adjustments.

While it still isn’t a fool proof way of securing the Grids, it will provide a good level of security from accidental adjustment.

Structure and Partitions

When you have structural walls and partitions intersecting in your model, it is important to get their intersections looking correct. Revit will always try to join your walls together and usually the resulting intersections is shown correct graphically, in the case of structure and partitions this is where the ‘Disallow Join’ tool can give you a preferred result.

The example below indicates graphically when the walls are automatically joined and when the partition has had the ‘Disallow Join’ applied.

To use the ‘Disallow Join’ just select the wall and right-click on the dot at the end and you will have an option to ‘Disallow Join’.

You will notice that the intersection of the joined walls results in a change in line weight of the structural wall at the intersection, this is not desirable.

When the partition has had the ‘Disallow Join’ the structural walls line weight is continuous and graphically gives the desired result.

So, the moral is to always check the graphical output of your model and don’t settle for what Revit applies automatically.

Associate Family Parameter

When you are working with nested families associating parameters can really help linking your parameters from the nested family into the parent family. The only problem is that unless you know they are there you would miss the Associate Parameter button.

When you select your nested family any of their instance parameters are visible, in the Properties Dialog box the little grey button on the right is the Associate Parameter button. You select this to associate a parameter from the nested family to a parameter in the parent Family.

Dimension Visibility

This is more of an observation of Revit behaviour rather than a tip, but it may be a useful thing to know.

When you have created dimension strings and the elements dimensioned are no longer visible, the dimensions try to adjust accordingly (in some cases).

If I turn the Visibility of the windows off, the dimension string remains but hides the dimensions that relate to the window. The dimensions string can still be selected as one element.

When the windows are turned back on the dimensions will reappear.

If you adjust the View Range of the view, to a range where the doors and windows are no longer visible (moving the cut plane above the head height of the elements). The dimension string still remains intact and visible, even though the doors and windows are no longer visible in the view.

Project Info and Shared Coordinates

When you are working in a Workshared Project, that utilises Shared Coordinates and Linked Revit Models, one side effect is that whenever you alter the location of a Linked file you become The Owner of the ‘Project Info’ Workset in the linked file. Especially if you don’t save the position back or synchronise the file.

So if you open a linked file, even to have a look and accidentally move one of the linked models, you may be getting a call from one of the other Revit users to relinquish the ‘Project Info’ Workset, even if you think you haven’t saved anything.

Revit knows where you have been and what you have been doing!!!

It is watching you right now!!! :)

Computation Height

If you are placing rooms in your Revit model and you have a room that seems to be enclosed on all 4 sides and yet when you go to place a Room, Revit informs you that it is not enclosed. It may be because of the Levels ‘Computation Height’.

Revit identifies the enclosed perimeter of a room at a distance above the level, set by a parameter called the Computation Height. By default the computation height for all levels is set to 0, and usually it works except if you have the base of the walls set above the level, like in the case of a room being set on a plinth or a mezzanine.

If you need to adjust the Computation Height, you have to go to an elevation or section view, select the base level line and look at the Properties palette, under Dimensions, and enter a value in the Computation Height parameter that will raise it up to a level above the base of the walls.

You room now will be enclosed.

If you have sloping walls in your model, be aware that the Areas and Volumes calculated will alter depending on the computation height set.
