Modify Panels


This command brings up another menu with seven options for modifying the panels.


This command automatically draws individual sheets on a selected roof plane in the model. You would use this command to change the starting point of the sheets on a plane.

After you select the command you are prompted to select the plane you want to generate the sheets on. Then you locate a point through which you want a sheet edge to go.

After you have located the point, the sheet alignment is updated to suit.

The following diagram shows the selection of a plane (d1) then snapping to the hip apex (d2). This forces the seam to go through the ridge apex point.




This command lets you split metal panels on a roof based on maximum length of the panels or by the positions of battens on the roof.

The dialog box displays parameters for standard panels and the splitting methods you can use.

Overlap – Bottom of Panel sets the amount added to the sheet for lap. It is, in actual practice half this amount as it is calculated about the centre line of the purlin or batten.

Underlap – Top of Panel is the amount added to each panel at the top of the panel and this is also calculated about the centre line of the purlin or batten.

If the base of the panel is at the eave, then the eave overhang value is added to that panel length.

The panel parameters of “Eave overhang” are set under the Gen-Panels > Allowances option.


Splitting Methods

Specify/Use the maximum panel/stock length

This method will use the maximum panel length you defined for this panel to split the panels in the roof or the number you specify when prompted –

The length starts at the base of the panel. You can modify which panels are split by selecting an option under “Apply split to”. Here you can limit the splitting to a single roof plane or a single panel rather than splitting all panels on the roof.

Select the batten up to the maximum length

This method lets you select the batten to split the panels. In this case, you need to select the batten for each roof plane.

Auto select the batten up to the maximum panel length

For this method the split position will be at the intersection of a roof batten which falls short of the maximum panel length. (You must have inserted battens using Cover > Battens for this method to work). Again, you can modify which panels are split by selecting the relevant “Apply split to” field.

Insert a new panel between battens (Roof Lights)

This method lets you insert a new panel between battens and adjust the lengths of the adjoining panels to suit. You would have already split the initial panels at a batten before carrying out this command. After selecting the new panel to insert, you then select the 2 battens between which the new panel will be inserted. You then select pairs of panels, each on the same run which will be trimmed back to squeeze in the new panel.


This command allows you to merge two panels together. You can either merge two panels butting into each other to make a longer panel or two adjacent panels to make a wider panel


This command allows you to change the material for individual panels. By selecting this command the roof metal panel dialog appears. Simply click the change button, select the new material and click [OK]. Crosshairs will appear and the panels will become highlighted. Simply select the panels that you would like to change, right click the mouse and confirm the entities. You will need to Tally the panels for the changes to be calculated.


This command allows the operator to change the calculated length of an individual panel, or group of panels by adding or subtracting and amount to or from the calculated length. This function allows for the panel length(s) to be adjusted subsequent to a site check-measure, without remodelling the entire job.

Select the panels to add/subtract an amount to; confirm selection.

Then specify the amount to add or subtract. A [+] sign adds to the calculated length, a [–] sign subtracts from the calculated length.

This will subtract 50mm from the calculated length.


This command allows you delete singular panels manually or every panel shorter than a specified length. By selecting this command the following dialog will appear.

By setting a number in the Select Sheets Shorter than field, then clicking Delete, any panels shorter than this length will be deleted automatically. By clicking on the Delete Sheets Manually, crosshairs will appear and all of the panels will be shown, simply click on the panels to delete. When you have selected all of the required panels, right click the mouse and confirm the entities.


This command will automatically re-number all of the panels for you.


This command will highlight all of the panels.



Should the location of the annotation still be difficult to read, a function exists to move the annotation and the leader line repositioned to suit. Select the option Move-Text and the prompts guide you through selecting, moving and moving the text and reposition the leader line. If you move the text, the software remembers where you move it to when the panels are ‘re-tallied’, unless the text is deleted.


This button also provides for deleting or adding a leader line to a panel annotation.
