Floor plan layout and loading plan of 1st floor are shown below. We are going to use following features while modeling on this floor.
→ Slab edge & slab piece
→ Slab opening
→ Copy from
→ Overlay above floor drawings
→ Circular & arbitrary & rectangular column
→ Column section change
→ Column transfer by slab
→ Shear wall & analytical wall
→ Shear wall opening
→ Beam & analytical beam
→ Area loading
If the reference drawing of 1st floor is not overlayed;
Go to 1st Floor → Overlay
Select 1st Floor linked drawing
Unselect ( if selected) other linked drawings
Click OK
Drawing Slab
Draw slab edge using slab edge command as explained before.
Draw slab pieces shown in reference drawings as expained before.
Or
Copy slab pieces which are the same from floors above.
You can copy slab pieces and slab openings at the same time.
Be aware that there is a transfer slab at 1st floor. Draw the slab transfer as 18” slab piece.
Edit the properties of slab objects in spreadsheet
Drawing Opening
Copy the openings which are the same from floors above if you did not copy at the same time with slab pieces.
Or
Draw the openings using commands shown on the right.
Drawing Columns
You must set foundation drawing as reference drawing file of 1st floor to see the columns below.
Go to Stories item in tree view
Change the drawing file of 1st floor
Select below plan (foundation) as drawing file
Go to 1st Floor → Overlay
Select 1st Floor linked drawing
Click OK
Now you see the columns and shear walls below for 1st floor.
Copy the columns which are the same from floors above
Be aware that there are discontinuous columns at 1st floor. Do not copy the columns to be transferred by slab.
You can see which columns are discontinuous by overlaying the columns above and reference drawing at the same time.
Go to 1st floor → Overlay
Select columns of 2nd floor
Select 1st floor linked drawing
Click OK
Columns of 2nd floor and reference drawing of 1st floor will be overlayed as shown below.
Drawing Shear Walls
Draw shear wall objects you see in the floor plan as explained before.
or
Copy shear wall objects from floors above.
Drawing Beams
Draw beam objects as explained before .
or
Copy beam objects from floors above.
Modelling of 1st floor is completed. Updated 3D view is shown below.
