Position and Elevation

The Position and Elevation part of the Create Rung Ladder window contains all the tools to select the position and elevation of the rung ladder and if required modify the position or elevation.

By default, the Evaluation part of the Create Rung Ladder window, is populated with the statement Top Exit Edge and Bottom Elevation not specified.

Top Position

The top position of the rung ladder element defines the position and direction of the rung ladder. The position of the rung ladder is the center point of the top face of the top rung (level with the FFL), use the Top Position part of the Create Rung Ladder to select the position of the top of the rung ladder.

From the Top Position part of the Create Rung Ladder window, click Pick Top Exit Edge (FFL) you are prompted to SLH Rung Ladder - Pick Top Exit Edge:

Once selected, the Top Edge is labelled in the 3D view and the Top Elevation (FFL) field is populated with the elevation.

Front Exit Ladder

For a front exit ladder, the position of the rung ladder is offset from the picked edge top by the foot clearance. The direction of the rung ladder is perpendicular to the picked edge top.

Side Exit Ladder

For a side exit ladder the position of the rung ladder is offset from the side exit cage clearance plus half the cage width. The direction of the rung ladder is parallel to the picked edge top.

Bottom Elevation

The Evaluation part of the Create Rung Ladder window prompts Bottom Elevation not specified. Click Pick Bottom Elevation (FFL), you are prompted to SLH Rung Ladder - TO Elevation (Distance[0]): Snap.

Once selected, the Bottom Elevation is labelled in the 3D view, and the Bottom Elevation (FFL) field is populated with the elevation.

If required you can modify the position of the top exit edge, click Modify Position to display the Rung Ladder Position window.

Modify the position of the rung ladder as required.

Click Offset to modify the position of the top exit edge as an offset value measured from the original position. Click Return from offset mode to exit the offset display.

Click Apply to modify the position of the rung ladder.

Click Dismiss to discard any changes and close the Rung Ladder Position window.

Once both the Top Exit Edge and Bottom Elevation have been selected, the Evaluation part of the Create Rung Ladder is populated with the statement Climbing height complies with the standard.

Positioning Tools

Use the Positioning Tools part of the Create Rung Ladder window to flip the direction of the ladder or reposition the ladder from a dominant foot clearance edge. The ladder can also be moved in the X or Y direction.

If required, you can flip the ladder direction 180 degrees across the picked exit edge, select Flip Rung Ladder Direction.

Pick Foot Clearance Edge

Pick Foot Clearance Edge allows you to reposition the ladder from a dominant foot clearance edge.

• For front exit ladders, an edge that protrudes further than the top exit edge can be selected and the ladder is then positioned away from the exit edge so that the foot clearance is maintained.

• For side exit ladders, the ladder is positioned along the exit edge and against this picked foot clearance edge.

From the Positioning Tools part of the Create Rung Ladder window, click Pick Foot Clearance Edge. You are prompted to SLH Rung Ladder - Pick Foot Clearance Edge.

X Offset

The selected exit type determines which direction the ladder is moved along the top exit edge.

• Front Side Exit - the ladder is moved along the top exit edge in the X direction.

• Left/Right Side Exit - the ladder is moved along the top exit edge in the Y direction.

For the purposes of this user guide, a ladder with a front exit is moved along the top exit edge in the X direction.

Use the X Offset to position the rung ladder a pre-set distance from an object along the top exit edge.

Input an offset value into the X Offset field (the default units are mm), then click Pick Offset Edge, you are prompted to SLH Rung Ladder Offset Position (Snap) Snap: in the 3D view. Once the offset is picked, the rung ladder is offset with respect to its centerline.

Nudge

Use the Nudge arrows to move the rung ladder incrementally (user defined) along the upper reference edge.

Click Build Rung Ladder to create a new rung ladder element and close the Create Rung Ladder window.
