# Modify Brace Group
### Add Diagonal Bracing
**Add Diagonal Bracing** – enables options for adding diagonal braces in the brace group.
*Diagonal braces can be disabled:*
*Example with wood floor:*
*Example with metal frame - diagonal braces can be disabled:*
### Diagonal Brace sizes
**Type –** select the family and type which will be used for diagonal brace. Default family is **M\_WF Plate.rvt** (for Metric projects) and **I\_WF Plate.rvt** (for Imperial projects).
**Width (b)** – shows b size of selected type.
**Depth (h,d) –** shows h or d size of selected type.
**Define Depth (h,d) by Layer Thickness** – **Wall+** will automatically create new type for selected family with new depth equal to selected wall layer thickness.
### Rotate 90°
**Rotate 90°** – diagonal brace can be rotated 90 degrees to its initial position.
*Example: when **Rotate 90*****°** *is switched ON:*
*Example: when **Rotate 90*****°** *is switched OFF:*
### Extend Ends
**Extend Ends** - extends diagonal brace ends when it connects to other elements.
*Example: when **Extend Ends** is switched OFF:*
*Example: when **Extend Ends** is switched ON:*
### Add Diagonal Last
**Add Diagonal Last** – tries to finish a group with diagonal braces.
### Add Bridging/Nogging
**Add Bridging/Nogging** – enables options for adding horizontal bridging/nogging in the brace group.
*Horizontal braces can be disabled:*
*Example with wood floor:*
*Example with metal frame - horizontal braces can be disabled:*
### Add every Second
**Add every Second** – adds every second horizontal brace in the brace group.
*Example: when **Add every Second*** *is switched ON:*
*Example: when **Add every Second*** *is switched OFF:*
*Example with wood floor - when **Add every Second*** *is switched ON:*
*Example with wood floor - when **Add every Second*** *is switched OFF:*
*Example with metal frame - when **Add every Second*** *is switched ON:*
### Start from Even Number
**Start from Even Number** **–** possible option when **Add every Second** option is enabled. It starts every second horizontal element from even number.
*Example, in the left side **Start from Even Number** is switched OFF, in the right - switched ON:*
### Add as Virtual
**Add as Virtual –** deletes horizontal bridging/nogging in the brace group but keeps the distances between diagonal braces the same as if there were horizontal braces.
*Example: when* ***Add as Virtual*** *is switched OFF:*
*Example: when* ***Add as Virtual*** *is switched ON. The distances between diagonal braces are the same as if there were horizontal braces:*
*Example: when* ***Add Bridging/Nogging*** *is switched OFF. The distances between diagonal braces are recalculated:*
### Calculation from Bottom Plate Axis
**Calculation from Bottom Plate Axis** – starts calculation from bottom plate axis.
### Spacing Type
**Spacing Type** – define spacing calculation rule: **Fixed Spacing**, **Maximal Spacing**, **Fixed Angle**, **Fixed Number and Fixed Spacing**, or **Fixed Number**.
The options below will change regarding this setting.
*Example: when **Spacing Type** = **Fixed Spacing** and **Spacing = 600**:*
### Brace Connection Offset from Plate/Bridging/Nogging
**Brace Connection Offset from Plate/Bridging/Nogging** – brace offset from connection point with a plate, bridging, or nogging.
*Example: when **Brace Connection Offset from Plate/Bridging/Nogging** = 100:*
### Connection Offset between Brace Elements
**Connection Offset between Brace Elements** – defines the offset between brace elements.
### Brace
**Brace** – select brace and stud connection cutting type.
Possible options: **Don't Cut**, **Cut Studs** and **Cut Bracing**.
*Example with wood wall - when **Cut Bracing** is selected:*
*Example with wood floor - when **Cut Joists** is selected:*
### Bridging/Nogging
**Bridging/Nogging** – select bridging/nogging and stud connection cutting type.
Possible options: **Don't Cut**, **Cut Bridging/Nogging** and **Cut Bracing**.
*Example with wood wall - when **Cut Studs** is selected:*
*Example with wood floor - when **Cut Joists** is selected:*
### Frame Side
**Frame Side** – select whether a brace group should be applied in the center, external, internal, or on two sides of the frame.
*Example with wood wall - when **Frame Side** = **Two - Sided**:*
*Example with wood wall - when **Frame Side** = **Center**:*
*Example with wood floor - when **Frame Side** = **Two - Sided**:*
*Example with metal frame - when **Frame Side** = **Two - Sided**:*
### Build in Place
**Build in Place** – writes Yes/No information into the brace instance parameter if it is build-in-place or is prefabricated with whole wall frame. Later this parameter can be used in schedules or view filters.
*Example with wood frame:*
*Example with wood floor:*
*Example with metal frame:*
