4.1 Add mid floor




  


  • Internal load bearing walls are highlighted.

     

  




Switch to 1st Level deck layout


  • Before drawing the floor you need to switch to 1st Level deck layout.
  • In case you are in 3D view just press 'F2' to switch to 2D view.




Add Reference Drawings or Set visibility 


  • In 'Modelling' tab  Add ‘Reference Drawings’ → ‘Quick Load Drawing-Model Pair’.

Or  Set Visibility


  • Select 'Ground floor walls', since you want to add mid floor over it.

  • Before you add the mid floor, make sure that the floor / room height and floor thickness is set to suit or as per the requirement.
  • In 'Project Document Browser'  select 'Settings' right click and from the contextual menu select 'Edit 3D Levels'


  • So we have fixed 2700mm room height and 419 deep mid floor ( 400 deep floor trusses and 19mm  yellow tongue floor board.




Add Floor to 1st Level deck layout


  • In 'Modelling' tab click on Floor icon.

  • Press ESC to exit the floor command.
















  • Press 'F2' to switch to 3D view






Create Stair void / Whole in the floor


  • Change to 1st Level, deck layout drawing pair and in 2D view. and 'Plane Structure' tab get activated.
  • Select Hole icon  and  'Hole' 







OR



  • Select the floorright click and from the contextual menu select ‘Create Hole’.



  • Pick a rectangular point ( as per the dimensions shown ) at the end right click and confirm. Or hit ‘V’

  • Fill out as per the dialog box and click OK


  • Rotate the stair with the arrow keys for correct position ( As shown ).


  • Press 'F2' to switch 3D view to ensure the stair is in the correct position.


TIP

Use shortcut key 'W' on the keyboard to see through the surface.

You can also select an object through a surface in the model by pressing the 'W' key.

This is a one-off function, so you have to reselect it, if you want to select more objects through a surface

  1. Select an object or profile. ( Hold down the CTRL key to select several profiles )
  2. Right-click to open the context-sensitive menu.
  3. Select Trim to Plane.
  4. Move the cursor over the surface, which you want to select through.
  5. Press the 'W' key. The program will make the nearest surface transparent. Keep pressing the 'W' key until the desired surface is visible.
  6. Click the surface.



  • You can all also set 3D limits  
      from the tool strip for better visibility.

  





Create Floor Joists ( Floor Trusses )

  • Now we can create 400 deep Floor Trusses. You can use this function ( shown below ) to define a truss area and to add trusses to a floor. The top and bottom surface of the truss area are determined by the top and bottom surface of the floor's FRAMING type layer.
  •  Change to 1st Level, deck layout drawing pair.
  • In ‘Modelling’ tab → Truss → Floor Trusses


  • 'Truss Parameters' dialogue box appears.


  • Label type can be changed but here we will only change Spacing to 450 Centers.


  • In this exercise we want to use blocking between the floor trusses ( by the external walls / end of  floor truss ). So Tick  'Blocking' and 5mm tolerance at each end ( can be changed as per the requirement )


  • Click OK.


  • Vertex prompts you to Select area. Right click and click OK to confirm or press 'V' to  confirm
