If you ever need to add a Level parameter to you tag, when you place your label you will notice that most of the Categories won’t have the Level Parameter in the ‘Select available fields from:’ list.

So you have to apply a little work around to gain access to this field.

  • Firstly change the Category of the Tag to a ‘Ceiling Tag’. 
  • Place a Label on the screen and select the Level parameter from the fields. 
  • This will create a Level Parameter Label. 
  • Select the Label on the screen and ‘Cut to Clipboard’. 
  • Now you can change the Category of the Tag Family to the one you require. 
  • Paste the Label back into the Tag family and you now have a Label reporting the Level parameter.

Formula Greater Than or Equal To

If you have a situation where you would like to control a parameter determined on whether another parameter is Greater Than or Equal to a third parameter. You might think that the formula should read….

Parameter A = Parameter B >= Parameter C

The only problem is that Revit won’t allow you to insert the condition >= in the Formula, and will return an error.

So if we think in reverse and work with a ‘not’ statement we can use Parameter B < Parameter C.

So the formula will read….

Parameter A = not(Parameter B < Parameter C)

Sometimes you have to think a little out of the box to bend Revit to your will!

Paste to Selected Levels

If you have a selection set you would like to copy to multiple levels in your project model, you can quickly and easily complete this process by using the Paste  ►Select Levels tool.

Firstly select the Elements you would like to copy.

Then using the Copy to Clipboard Tool in the ribbon above, or using the ‘Ctrl’ + ‘C’ on the keyboard.

Now click the ‘Paste’ drop down arrow, to bring up the extra ‘Paste’ options.

Click the ‘Aligned to Selected Levels’.

This will bring up the ‘Select Levels’ dialogue box where you can select the levels to paste the elements. You can select multiple Levels by holding down the ‘Ctrl’ or ‘Shift’ Keys. Once selected click the ‘OK’.

Family Creation Process

When creating families for your project here are some basic best practices to keep you family running smooth and trouble free.

  1. Plan your family before you begin creating, this will allow you to make informed decisions during the creation process. Try to keep it simple for others to use and edit.
  2. Select the correct Family Template file to start. 
  3. Define Category and additional Sub-categories. 
  4. Create a skeleton of Reference Planes. 
  5. Dimension and create appropriate Parameters and apply to Reference Planes, (remember to utilise Shared Parameters where required). You should also create your Parameters in the appropriate ‘Group Parameter Under:’ section, this will help users find your parameters quickly. Don’t put everything under ‘Other’. 
  6. Test your Parameters, flexing your model and ensuring you don’t get any errors. (You can create additional ‘Family Types’ of you family, this will help testing as you can switch between Types rather than having to alter values all the time.) 
  7. Create 3D and 2D elements and lock them to the Reference Planes where required. This process may include the addition of nested families. 
  8. Apply Visibility Settings to control individual element visibility. 
  9. Test your Parameters again. 
  10. Save you Family, in the correct location and Name it in accordance with the your offices' Naming Conventions. Remember the model is going to be sent out of the office, People outside of your company are going to need to find and analyse these families. 
  11. Test the Family in a Project environment. Open a new project and test the family before you load it into your actual project model.

Although there are many variations of Family creation, if you follow these simple steps no matter how complicated your Family is it will have the best chance of working first time, every time.

The common thread through this outline is to test and test often.

Browser Organisation

A really quick way to change you Project Browser Organisation without having to go to the View Ribbon and then into the User Interface tool, is to highlight the ‘Views (all)’ heading at the top of your Project Browser and then in the Type Selector in the Properties dialogue box, select the Browser Organisation you would like to apply.

This process also works for the Sheets Browser Organisation.

When you are working on a workshared project file it is always a good idea to keep an eye on the Active Workset. Whatever the Active Workset is set to, this is the Workset all of your new modelling will be created under.

You can find the Active Workset in 3 locations.

In the Collaborate Ribbon, In the Worksets dialogue box, or the most convenient which is located at the bottom of your modelling area.

The Active Workset can change without you realising, resulting in your work being located on the incorrect Workset. This is because different users change the Current Active Workset in their local file. When they synchronise it will make their Active Workset as the default Active Workset next time you open the Central File.

The Moral of this story is to keep an eye on the Active Workset, when you next open (or create) your Local file.

Dynamo - Twisting Tower

Whilst I primarily use Dynamo for BIM Management tasks, I do like to delve into the Computational Modelling for facade optioning and building forms.

I am constantly getting asked about.... How do I create one of those twisting towers?

So I decided to put up a small tutorial and the Dynamo script for anybody interested in creating a twisting tower.

Starting with a Mass family, I create a rectangular shape on the Ref Level and a point element to act as my rotation point.

From there Dynamo takes over with inputs for "Number of Levels", "Floor Height", "Bottom Floor Rotation" and "Top Floor Rotation"

Just select the Rectangle and the point and twist away.....enjoy.....

You can take this much further by adding floors and facade elements, but playing with the form is so much fun!!!
