Load Cases

Organize your loads into logical groups for analysis.

What are Load Cases?

Load cases group related loads together:

• Dead Load (DL): Permanent loads (self-weight, fixed equipment)
• Live Load (LL): Variable loads (occupancy, furniture)
• Wind Load (WL): Wind pressure loads
• Snow Load (SL): Snow accumulation loads
• Seismic (E): Earthquake loads

Managing Load Cases

Open the Load Cases panel from the left sidebar:

• Add: Create a new load case
• Rename: Change load case name
• Delete: Remove a load case and its loads
• Duplicate: Copy a load case

Active Load Case

The active load case determines:

• Which loads are displayed on the model
• Where new loads are added

Click a load case to make it active. The active load case is highlighted.

Load Case Colors

Each load case has a unique color. Loads are displayed in their load case's color for easy identification.

Self-Weight

Self-weight can be enabled per load case. When enabled, the weight of all members (based on their section area and material density) is automatically applied as a distributed load.

Analysis with Load Cases

When you run analysis:

• Each load case is analysed separately
• Results can be viewed per load case
• Load combinations can combine results from multiple cases
