4.4.15.4. Connection collision

Collision Connection

The Collision function in SuCri (Module 3 - Connections) allows you to precisely define connections between profiles. It assumes that the endpoint of the center of gravity axis of the profile to be connected (beam) lies on the center of gravity axis of the connecting profile (column). Although it is technically possible for a beam to end in front of or behind the center of gravity axis, an actual intersection point ensures the correct placement of the connection by the software.

Prerequisites

Installed AutoCAD Plant 3D or Advance Steel.
Installed and licensed SuCri Plugin (Module 3 "Connections").
Existing profiles in the model (at least one beam and one column) whose center of gravity axes ideally intersect.
Active SuCri workspace in the ribbon.

Step-by-Step Instructions

Step 1: Accessing the SuCri Connections Module

In your CAD program, navigate to the SuCri tab in the upper ribbon area.
Click on the corresponding icon for connection definitions within the "Connections" group.

Expected result: The SuCri connection interface or a submenu with various connection types opens.

Step 2: Selecting the Connection Type "Collision"

Look for the Collision entry in the opened menu and select it.

Expected result: The command line prompts you to select the first profile (beam).

Step 3: Selecting the First Profile (Beam)

Click on the profile in the model that is to function as the beam (the component to be connected).

Expected result: The profile is visually highlighted, and the system prompts you to select the column.

Step 4: Selecting the Second Profile (Column) and Orientation

Move the mouse pointer over the column (the profile to which the connection is being made).
Click on the column to confirm the selection.

Important for asymmetrical connections: For components such as angles or sloping brackets, the mouse position when clicking on the column determines the alignment. Click on the right of the column for a right alignment, and on the left for a left alignment.

Expected result: SuCri generates the connection based on the center of gravity axes and the mouse position and places it in the model.

Step 5: Review and Adjustment

Visually check the generated connection for correct positioning.
If a connection palette opens automatically, you can adjust parameters such as weld types or bolt diameters here.

Expected result: The connection is fully configured and integrated into the model.

Important Notes

Center of Gravity Axis: Accuracy depends on the clean modeling of the center of gravity axes.
Asymmetry: Remember: The mouse position when clicking on the column is crucial for the orientation of the connection.
Shortcuts: Use ESC to cancel, ENTER to confirm, and F3 for object snap (OSNAP) to accurately select profiles.

Troubleshooting

Connection is not created: Check whether the center of gravity axes of the profiles actually touch or intersect. Move the beam minimally if necessary.
Incorrect alignment: Repeat the process and pay attention to the position of your mouse pointer relative to the column axis in Step 4.
SuCri command missing: Ensure that the plugin is correctly licensed and restart the CAD program if necessary.
