Modify a Section

As a design progresses it may be necessary to modify a section's parameters.

1. From the 3D graphical view, select the section to be modified as the CE.

2. From the main menu toolbar select Modify > Section > Specification to open the Section Specification window to change the specifications of the section.

   

3. Click Apply to accept the changes or click Dismiss to discard any information and close the Section Specification window.

   You must now select the section whose definition is to be changed as the CE.

4. From the main menu toolbar select Modify > Section > Definition to open the Modify STCN window and the Positioning Control toolbar.

   By default the Start position of the current element displays and shows XEast, YNorth and ZUp co-ordinated with respect to the world.

   

   

   The Start position is indicated in the 3D graphical view.

5. You can enter values in the Start, End or Centre fields to specify the point on the element to which the position co-ordinates apply.

   Dependant on the option specified the application of modified co-ordinates has this effect on the element:

   • Start - Relocates the start position of the element to the specified co-ordinates, but its end position remains unchanged.

   • End - Relocates the end position of the element to the specified co-ordinates, but its start position remains unchanged.

   • Centre - Relocates the entire element, its centre is located at the specified co‑ordinates and the start and end positions are modified.

6. To define a position by reference to design items that already exist, use the Positioning Control toolbar and the cursor to identify the required position by picking it in the graphical view.

7. Use the Settings option to change the length and direction of the section.

8. Use the End Direction option to change the end direction to Perpendicular or maintain the original direction.

9. Click OK to modify the section.

10. Select Modify > Section > Justification from the main menu toolbar to display the Section Justification window.

    The Section Justification window will be displayed in an inactive state before the section pick is completed.

    

11. To change the justification, select the required Pline Justification from the drop-down menu.

12. To select the justification manually from the 3D graphical display, click Justification.

    The prompt ‘Identify Pline to justify to.’ appears.

13. Select the pline with the cursor.

14. To maintain attachment to associated sections, select the Re-trim attached section checkbox.

15. Click Apply to make the changes or click Dismiss to discard any inputs and close the Section Justification window.

The modification of the wall Member Line, Joint Line and Joint Position Line is the same.

The Modify Section Justification and Member Line can be used to modify the attributes of a GENSEC. The Modify Joint Position and Joint Line can be used to modify the attributes of a FIXING element, owned by a GENSEC.
