This worked example uses the equipment rack created in previous exercises. It demonstrates the creation and modification of a panel.

8.7.1 Creating the Panel

 Enter the Panels & Plates application by selecting Design > Structures > Panels & Plates… from the main menu. Clear the Draw List and add back the /EQUIP_SUPPORT structure. Set the limits to the

Draw List and view direction to Iso 3.

 Create a SBFR named EL(+)107820_TOS_PLATE owned by FRMW EL(+)107820_TOS. Make the SBFR the CE and set the Storage Areas by clicking the appropriate buttons on the Panels & Plates toolbar. Select Create > Panel… from the main menu to display the Create Panel form and enter 20 in the Thickness textbox and select Bottom from the Justification options list. Leave the Representation settings at their defaults.

 Make sure the Pline rule is set to Normal and click the Derive points from graphic picks button in the Create Methods area of the form.

Set the Positioning Control toolbar to Pline and Intersect. Zoom into the top of column C3 and select the outer top of steel (LTOS or RTOS) Plines of the two connecting beams (not the cantilever beam).

A text aid will be displayed at the intersection of the Plines showing the Origin of the panel.

Note that the message on the form now reads: 1 Vertices

defined (no Panel created).

 Pan the view to the top of column H3 and again select the outer top of steel (LTOS or RTOS) Plines of the two connecting beams.

Another text aid will be displayed at the intersection of these Plines at the position of the new vertex.

Note that the message on the form now reads: 2 Vertices

defined (no Panel created).

 Pan the view to the top of column H5 and again select the outer top of steel (LTOS or RTOS) Plines of the two connecting beams (not the stair landing beam).

Another text aid will be displayed at the intersection of these Plines at the position of the new vertex.

Note that the message on the form now reads: 3 Vertices

defined (Panel created).

 Continue picking vertex points At the corners of the cantilevered stair landing using this method. It may be necessary to switch to

wireline mode (F8 key) where the landing meets the main structure.

 Finish the panel by panning to the top of column C5 and selecting the outside TOS Plines on the two connecting beams (not the cantilever beam). Click the OK button on the Panel Creation form to create the panel.

The deck plate should look like this:

8.7.2 Modifying the Panel

The panel requires modification to create cut-outs in the panel edge around the columns. This is achieved by introducing new vertices into the loop.

 Make sure the panel is the CE and select Modify > Extrusion/Panel… from the main menu to display the Loop Vertex Editor form. Note that an axis aid, showing the axes with respect to the panel, is placed at Vertex 1, the panel origin. First new vertices will be added to the PLOO to make a cut-out around the top of column C3. Zoom into the top of column C3.

 Change the Positioning Control toolbar settings to Pline and Snap and press the F8 key to change the 3D View to wire-line. Make sure the Vertex counter is on 1 and the co-ordinates are X 0 and Y 0. The first new vertex is to be positioned between vertex 1 and vertex 2 and will have the same X co-ordinate as vertex 1.

 Click the Create points button and note that the Modify button at the bottom of the form has changed to the Create button, i.e. the form is now in Create mode. Click the X checkbox to lock the co-ordinate and pick the Pline on the north-west corner of column C3. A New vertex label is displayed at the new vertex position. Click the Create button on the form to create a new vertex 2.

 Rewind the vertex counter to vertex 8, i.e. the last vertex in the loop. Unlock the X co-ordinate and lock the Y co-ordinate. Pick the Pline on the south-east corner of column C3. A New vertex label is

 Vertex 1 needs to be moved to a new location. Click the Select point to modify button in the Mode

Selection area of the form and select vertex 1. The Create button has changed to the Modify button,

i.e. the form is now in Modify mode. Unlock the Y co-ordiante and select the Pline on the north-east corner of column C3. A New position text displays the new position for vertex 1. Click the Modify button to move vertex 1 to its new location.

 Similar cut-outs need to be made around column E3. Set the vertex counter to 2, lock the X co-ordinate and click the Create points button. Pick the Pline on the south-west corner of column E3 and click the Create button to create the new vertex 3. Unlock the X co-ordinate and lock the Y co-ordinate. Press the F8 key and pick the Pline on the south-east corner of column E3. Click the Create button to create new vertex 4. Unlock the Y co-ordinate and lock the X co-ordinate. Pick the Pline on the north-east corner of column E3 and click the Create button to create new vertex 5. Unlock the X co-ordinate then lock the Y co-ordinate. Pick the outside TOS Pline on the beam between column E3 and F3 and click the Create button to create the new vertex 6.

8.7.3 Using a Vertex Group

Column F3, F5 and E5 require similar cut-outs to column E3. This may be achieved by creating a group of the vertices that form the cut-out around column E3 and moving it to the correct location before inserting it into the loop.

 Rewind the vertex counter to 2. Click the Select group to modify button in the Mode Selection area of the form to display the prompt ‘Pick points <escape> to select’ in the prompt area.



Graphically pick four points, in a clockwise direction around the cut-out at the top of column E3 and press the Esc key. The group will be defined by four spheres, one at each of the four vertices that form the cut- out with a larger sphere at the first vertex on the group, i.e. the group origin.

panel and aligned with the corner of the column. Set the vertex counter to 6 and click the Insert selected button in the Modify area of the form to insert the group into the loop and create the cut-out.

 Unlock the X co-ordinate and lock the Y co-ordinate. Pick the south-east pline of column F5. The group is now located correctly at column F5, however, the order of the vertices in the group must be reversed to fit the clockwise numbering sequence and the group must be mirrored to form a cut-out and not an outstand.

 Click the Reverse group definition button in the Definition area of the form. Note the group origin has been placed on the north side of the group. Click the Mirror button in the Modify area of the form to display the ‘Pick line to mirror about’ prompt and graphically pick the edge of the panel. The group is mirrored to form the correct sequence of vertices for a cut-out. Set the vertex counter to the vertex before the group origin (i.e. 15) then click the Insert selected button.

 Ensure the Positioning Control toolbar settings are set to Pline and Snap. Unlock the Y co-ordinate and lock the X co-ordinate. Pick the Pline on the north-east corner of column E5 to move the group. Set the vertex counter to 19 and click the Insert selected button to create the cut-out around the top of column E5.

 Create cut-outs around the tops of columns H3, H5 and C5.

 Click the Select All button in the Mode Selection area of the form. Enter 10 in the textbox in the

Expand/Contract area of the form and click the Contract group button. Note that the vertex indicators move to their new positions. Click the Modify button to contract the whole loop by 10mm.
