Visibility Graphics and Linked Files

When you link Revit models into your project, Revit allows you to control their visibility graphics in your host file. This can be controlled many ways….

By Host View – Visibility graphics is controlled by the host view.
By Linked View – You can use a view in the linked file to set the visibility.
Custom – You can independently control the visibility of the linked file.

When you select on the Revit Links Tab in the Visibility Graphics dialogue box, it will list all of the Revit links being used in the current project. If you expand the Revit Link, you will notice that there is a sub-category to the Revit link. This is the individual instance of the linked file and it can be controlled individually.

Changing from ‘Not Overridden’ can cause major headaches in your project file if you start manipulating the instance (sub-category) display settings unnecessarily, it makes visibility settings hard to find in views. Normally there is no need to adjust the visibility of the instance of the linked file, especially if there is only one instance (sub-category).

Please leave this as ‘Not Overridden’!

Use the main category of the linked file to control the visibility.

The only time you need to adjust this setting is if you have multiple instances of the linked file in your project that need to have their visibility controlled individually.

Wall Intersections, Structure and Partitions

When modelling in Revit the program defaults to joining walls when they intersect. When you model contains both structural walls and internal partitions the default doesn’t give you the correct intersection both physically and graphically. This is a situation where the walls should have the ‘Disallow Join’ function applied.

In the example below I have a partition wall intersecting with a structural wall. You will notice that the intersecting line weight does not show the structural wall continuous and the end of the partition extends into the middle of the structural wall.

If you right click on the dot at the end of the wall and ‘Disallow Join’, this will break the attachment of the 2 walls.

The end of the partition can now be dragged back to the intersection with the structural wall. 

The intersection of the walls is now correct.

I know that there are a few extra steps, but this will give you the outcome required to represent the model correctly in your documentation and also when it is exported for use throughout the Project Team.

Linked Levels and Grids

When you have linked Revit models loaded into you project file, the positioning is usually controlled by the shared coordinates system which makes the Grids and Levels of the linked file kind of redundant. This doesn’t stop them showing up in all of your Plan, Elevation and Section views of the host file.

A way of globally turning the Grids and Levels off in the linked model is to go to the Manage Links Dialogue box.

Highlight the linked project and select the Manage Worksets button.

This will open up the Manage Worksets Dialogue box for the linked file.

You can close the Workset for ‘Shared Levels and Grids’ by selecting the Workset and selecting the Close button.

If you ever need to check the linked files Grids and Levels, the Workset can still be opened through Manage Links.

Wall Length Adjustment

This is a relatively simple tip, but I was helping a user in the office today and when I adjusted an existing wall using this method, they exclaimed that they didn't know of this, just in case you didn't know....

 If you need to adjust the length of an already modeled wall, and one end is going to remain in its original location, select the wall and select the dot at the end that needs to be adjusted holding the left mouse button down, dragging the end of the wall in the direction of the adjustment type in the value of the desired overall length.

Another Interesting Error Message

I just love seeing the obscure warning messages…..we are getting quite a collection from Revit now….

Perhaps when they were writing the code for this one, they had been watching one too many Star Trek Episodes???

Schedule Hidden Fields

Scheduling in your project often calls for some sorting or filtering of the schedule fields. This can call for a bit of schedule magic, especially if you want a particular field to sort or filter the schedule but you don’t want that field to be visible in the final schedule.

This is where you can use a Hidden Field.

In the Example Door Schedule below, I want the schedule to group all of the Doors of the same ‘Construction Type’, but I don’t want the Construction Type to be visible in the final schedule.

To create this schedule ‘Construction Type’ needs to be one of the fields scheduled.

Then you can sort the schedule using the ‘Construction Type’ field. This will get the schedule in the correct order.

If you select the Formatting Tab. Highlight the ‘Construction Type’ field and tick the box labelled ‘Hidden Field’.

This will use the ‘Construction Type’ in the schedule to sort but hide it in the final schedule.

Rotation Center Point Correction

When we need to use the rotation tool in our model, the location of the rotation center point is critical to ensure our rotation is going to give use the correct final result.

When you select an element, pick the Rotate Tool (RO), Revit by default places the rotation point in the center of the element or elements selected. Very rarely do we want it in this location and we have to move it before we execute the command.

We have 3 options to relocate this point.
  1. Click + drag the point in the view
  2. Place Button (Options Bar)
  3. Space Bar (press to position the center point)

Using the Place button or Space bar we just have to click where the center point ought to be. These options are very useful if the center point is not visible in the view.

Using Click + Drag we need to click on the center icon (left mouse button), + drag it to the correct location. 

One thing that is often overlooked is the Copy, in the Options Bar. This will allow you to copy the element and rotate in one command. (Holding down the CTRL key will also activate the Copy option).
