Tut_1
Construct a basic corner scene with low polygon count

1 
Construct a plane (using keyboard entry) 200x200, with a 4polygon count in the front view. 
2 
Mouse right click and convert to an editable poly.
 
3 
Highlight polygon and with window/crossing clicked, drag to grab the bottom two polygons. Press ctrl and add the top right quadrant. Delete.
 
4 
Construct another plane, 200x200, 4polygon count using keyboard entry in the front view.
 
5 
Right click and collapse into an editable polygon. Keep the bottom left quardrant, deleting the other three.
 
6 
Repeat step 4 and 5 but in the left viewport and keeping the top right quadrant.
 
7 
Open the polygon count via views/viewport configuration/statistics and in setup click the polygon count and show in active view.
 
8 
Open the create/cylinder and set radius to 5 and height to 10 and create in the front view via keyboard entry.
 
9 
With the cylinder highlighted click align and click the back quad in the top view and align XYZ and centre for both objects.
 
10 
Repeat the construction of a cylinder via keyboard entry in the left view. Align in the same way.
 
11 
Check the polygon count. Reduce the height and sides parameters in the modify panel to get the count down to an acceptable qualitative level.
 
12 This should give a corner room view, with two possible wall lights, in the perspective port.
 
13 Drop a target camera into the top viewport and move it into position to view the room. Start with a 35mm lens but change to suit. Click the perspective view and press 'C'
 
14 
Place a target light as a general in the top view about the same direction as the camera.15 Drop a free light into the top viewport about the place of the right cylinder. Align it with that cylinder.
 
15 
Shift click and move to copy that light then align it with the other cylinder.
 
16 
Experiment with different light templates and change the Kelvin value of one to 15,000 and cast a shadow.

Tut_2
Modelling unique rings
The bevel and bevel profile can give you that individual shape you might be looking for.

1
Select create/shapes/doughnut and drag in top view. Create two doughnut objects positioned side by side. Set the Rad1=80 and Rad2=75 for both rings.

2
In top view select ring on left. Open Modifier/bevel. In bevel roll out set
start outline=0
height for Lv1,2,and3=20
Outline Lv1=15, for Lv2=-15
Then enable the smooth across levels option.

3
Select create/shapes/line and draw a profile curve in the front view from bottom to top, about the same height as the first ring. This curve doesn't have to be a closed spline.

4
Select the doughnut shape on the right, open the Modifier/bevel profile. In the parameter roll out select 'pick profile' button and select the profile curve.

5
Examine other possibilities.

 A path can be any chosen spline, closed or open. The following is a reminder:
