What is void Revit?

How do you make a void visible in Revit?

Revit 2021 has included Void visibility control under the void’s properties. With this yes/no visibility control called “Cuts Geometry” we can now use it’s link button to be able to control it with a visibility parameter of our choice, inside the family’s properties.

What does cut with voids when loaded mean in Revit?

“Cut with Voids When Loaded: When selected, voids created in the family will cut through solids. The following categories can be cut by voids: ceilings, floors, generic models, roofs, structural columns, structural foundations, structural framing, and walls.”

How do you use voids?

When to use Void or Value-Returning Functions:

1. Void Function: when must return more than one value or modify any of the caller’s arguments.
2. Void Function: when must perform I/O.
3. Void Function: when in doubt, can recode any value-returning function as void function by adding additional outgoing parameter.

What is void extrusion?

A solid or void extrusion is the easiest form to create. You sketch a 2D profile of the form on a work plane, and then extrude that profile perpendicular to the plane on which you sketched it.

Why is my void extrusion orange?

“When you create a void form while in the Family Editor, it will appear in the 3D views as a transparent form and as orange lines in plan and elevation views, as long as it is not cutting any solid geometry.” So, if it’s not cutting anything, then it’ll be orange.

How do you hide a void extrusion in Revit?

There is no way to control the Visibility of a Void. The best you can do is to add parametric constraints to the Void Extrusion so that it does not penetrate the target Solid Extrusion under the conditions specified by the formula.

Can a void cut a void in Revit?

Open the Revit family with unattached voids and click Create tab Properties panel Family Category and Parameters. In the Family Category and Parameters dialog, select Cut With Voids when Loaded and click OK. Load the family into the project and place it. Click Modify tab Geometry panel Cut drop-down (Cut Geometry).

Why do we use void?

In computer programming, when void is used as a function return type, it indicates that the function does not return a value. When void appears in a pointer declaration, it specifies that the pointer is universal. When used in a function’s parameter list, void indicates that the function takes no parameters.

What is the purpose of the void?

When used as a function return type, the void keyword specifies that the function does not return a value. When used for a function’s parameter list, void specifies that the function takes no parameters.

Why is void main used?

The void main() indicates that the main() function will not return any value, but the int main() indicates that the main() can return integer type data. When our program is simple, and it is not going to terminate before reaching the last line of the code, or the code is error free, then we can use the void main().

How do you make a void roof in Revit?

Create an In-place family roof at choosing “Void extrusion”. Ideally in a section view draw the contourline of the void using the “Pick line” option on the base of the inside edge of the roof. Use the “Cut geometry” command and select first the roof than the void. After that you can click “Finish” to execute the cut.

How do you cut a void wall in Revit?

Solution:

2. Create a new void extrusion that will define the opening.
3. Use the “Cut” tool and select the void geometry.
4. Finish the solid edition.
