I need to determine the coordinates where two members intersect.

Solution

The Intersect Selected Beams tool can be used to add a node at a location which can provide the coordinates of this location.

1. To determine if two beams do, in fact, intersect and to automatically select them, do the following:
   1. On the Geometry ribbon tab, select the Intersecting Beams > Highlight Intersecting Beams tool in the Beams group. The Intersect Members dialog opens.
   2. Type a tolerance value to use for determining if beams intersection. The default value is 1mm (0.03937 in.).
   3. Click OK.

If beams intersect, they will be selected. Otherwise, a dialog message will inform you that no beams intersect given the tolerance value used.

Alternatively, you can manually select the beams.

2. To add a node at the intersection, select the Intersecting Beams > Highlight Intersecting Beams tool in the Beams group on the Geometry ribbon tab.

The Intersect Members dialog opens.

3. Type a tolerance value to use for determining if beams intersection. The default value is 1mm (0.03937 in.).
4. Click OK.

A new node is added at this location. You can view the coordinates in the Nodes table.

Tip: Press <Shift+N> to display the node numbers.

Tip: You can view nodal coordinates in a tooltip using the Nodes Cursor tool. First, select the Structural Tooltip Options tool in the Options group on the View ribbon tab. In the Tool Tip Options dialog, check the Coordinates option and then click OK.

If you do not need to retain this node, then you can either:

• Use the Undo tool in the Quick Access toolbar, or
• Use the Merge Selected Beams tool in the Beams group on the Geometry ribbon tab to merge the concentric beams back to single members. This will also delete the orphan node created by the intersection tool.
