Autodesk Revit: Splitting Elements

In this Autodesk Revit tutorial, I am going to show you how to use the “Split Element” tool. There is a also video version of this tutorial which can be viewed by clicking the box below……

 

 

In order to demonstrate this tool, let’s first start by creating something to split! In the image below you can see that we have a single wall instance. We want to split it at the position shown with the red arrow….

Switch to the “Modify” menu and choose the “Split” tool. Please note that there are 2 versions of the Split tool- they are “Split Element” and “Split with Gap”. We will cover both of these in this tutorial. We will start with the “Split Element” tool. Go ahead and select this from the drop-down menu…..

 

 

As soon as you activate the “Split Element” tool, you’ll notice that your cursor changes to an icon of a knife / scalpel blade. You can now simply hover over the element you wish to split and Revit will display a blue line to indicate where the split will be made……

Go ahed and left-click with your mouse. Revit then splits the element at this point. In the image below you can see that we now have two instances of wall (of the same type)- which butt up against each other at the split point…..

 

These are now two separate walls and (as such) can be manipulated individually. If we go ahead and select the right hand wall, we can click (and hold) on it’s “Drag End” grip and shift the end of the wall over to the right…..

 

 

Let’s now look at the other version of the Split tool- “Split with Gap”. Go ahead and select this from the drop-down menu….

 

 

Notice how (with this particular tool) the Options Bar has a parameter for you to adjust- the “Joint Gap” parameter. This is the width of the gap that will automatically be created between the 2 elements when you use this tool. I am going to leave it on the default value of 25.4mm. Please note: There may be a different value shown here on your screen, depending on the Units you have set in your project.

 

 

 

So with the Gap width set, go ahead and hover over the wall. Notice the blue line that denotes where the split will be made. Go ahead and left-click your mouse to split the element and form the Joint Gap….

 

Note (in the above image) how a locked constraint is automatically formed between the 2 sections of wall. This is because Revit assumes you want this to behave as a single, overall wall- it just happens to have a joint in it.

This version of the tool (“Split with Gap”) is intended to be used when you need to model (in the case of walls) an expansion / thermal movement joint.

 

Key Points

  • The “Split” tool comes in two versions
  • Not all elements in Revit can be split using these tools
  • Walls, Detail Lines, Sketch Lines and Model Lines are elements that are commonly split using these tools
