This worked example creates two free holes, with and without a sleeve, and a fitting hole in a panel.
12.7.1 Creating a Free Hole
Select Design > Structures > Panel & Plates…from the main menu to enter the Panels & Plates application.
Empty the drawlist then add building B01 to the 3D view. Select a plan view north, then remove the roof panel from building B01.
Select Utilities > Steel Penetration > Create Hole… from the main menu to display the Create Penetration form. Click the Pick Penetrated Item button and pick the ceiling panel in the somewhere near the north west corner of the panel. The panel name is displayed in the upper form grid. Select Rectangular Hole - Type HR from the Hole Type list and click the OK button.
The hole is displayed graphically, using the default values at the point where the panel was picked.
Aids showing the position and the X and Y directions with respect to the panel are also displayed.
Clicking the OK button also displays the Hole Management
– Free Hole Definition form.
In the Hole shape parameters area of the Hole
Management – Free Hole Definition form enter the
following details:
Width - 2800
Height - 4000
Radius - 50
The hole shape changes to the reflect the new values in the 3D View. The width is in the Y direction and the height is in the X direction.
The axes directions depend on the relative positions of the first two vertices of the panel upon creation, i.e. the panel’s
Y direction is the direction between the 1st and 2nd vertices. In the Hole Position and Orientation area of the form enter a value of 2000 in the Y Offset textbox. Note that the hole has moved in the Y axis and the Y Offset value has been updated on the form.
Click the Align in X button. Set the Positioning Control toolbar to Element/Mid-Point and select the beam running east/west adjacent to the north west column.
Click the Associated elements tab on the form to make it current. In the Modify associated items area of the form click the Pick items button, note the prompt ‘Pick associated item:’, and select
the beam that was used to align the hole in the X direction. The SCTN, and db reference no., are displayed in the Current
associated items grid.
Press the Esc key to end the selection process.
This example is only to demonstrate the principle of associating design items.Click the OK button on the form to create the ‘virtual’ hole. Navigate to the virtual hole fixing and query the attributes. Note that the Spref has been set to /HM-HOLE/TYPE-HR and that the Design Parameters contain the entered values.
Create a new free definition hole in the north east corner of buiding B01. This time select a Rectangular Hole – Type HR with Sleeve from the hole type list. Enter the following values in the Hole shape
parameters textboxes: Width – 1500 Height – 1500 Radius – 25 Sleeve Height – 150 Sleeve Thickness – 10
Click the Align in X button. In the Positioning Control toolbar set the Pick Type to Element, the Pick Method to Distance and enter
1000mm. Select the beam running east/west close to the north east
column.
Click the Align in Y button. Leave the Positioning Control toolbar settings and select the beam running north/south close to the north east column.
Ensure the rotation is set to 0°. Click the OK button on the form to create the ‘virtual’ hole. It should look similar to the Iso 3 view shown.
Navigate to the ‘virtual’ hole fixing and query the Spref. Note that it is set to /HM-HOLE/SL/TYPE-HR, i.e. a different catalogue
12.7.2 Creating a Fitting Hole
Add the roof panel back to Building B01. Make the roof panel the CE and select Utilities > Steel Penetration > Create Fitting Hole… from the main menu. The Create Hole Fittings form will be displayed.
On the Fitting Definition tab Select /Managed- Access-Holes from the Table options list and Managed Access Holes from the Type options list. Select STANDARD-HATCH from the Item grid and note that a representation of the hatch is displayed in the form 3D View.
Click the Pick Penetration Item button and pick a point in the northeast corner of the panel.
The fitting is displayed graphically with its origin at the picked point. Graphical aids display the fitting/hole position and axes with respect to the panel origin. The Hole Position and Orientation and Adjust
fitting orientation areas of the form are now active
and the X Offset and Y Offset textboxes contain the respective values of the picked position
Enter a value of 13000mm in the X Offset textbox. Enter a value of 0mm in the Y Offset textbox. Select Back Face from the Panel side options list. Rotate the panel and note that the fitting is now on the ‘reverse’ side of the panel. Select Front Face from the options list to bring the fitting back to the original side of the panel.
Click the OK button on the form to create the ‘virtual’ hole.
The ‘virtual’ hole fixing owns a template (TMPL) element that owns an NXTR. This NXTR will be copied to the panel when the hole is approved.
12.7.3 Requesting and Approving the Holes
Select Utilities > Hole Management… from the main menu to display the Hole Association Manager form. Make the panel the CE and click the Apply filters button on the form to update the Hole Associations grid.
The Hole Associations grid on the form should display three new hole associations, HM-VH-0003, HM-VH-
0004 and HM-VH-0005 with a Discipline entry of GEN, GEN and FITT respectively.
Select the three associations by holding down the Ctrl key and clicking on each one in turn. All three associations will be highlighted. Right click in the grid and select Validate from the pop-up menu. All three holes will pass.
Click the Manage Selected Holes link label to display the Hole Management form.
Make HM-ASSOC-0003 current; click the Request link label under the Originator Tasks and then the Approve link label under the Reviewer Tasks, clicking the Yes button on the two status change confirmation messages.
Repeat the process for the remaining two holes. Click the Return to Hole Associations link label and dismiss the form. Save Work.
