Modelling - building - interior - Chairs

Draw line (use grid snap to obtain shown results) - top view - create - geometry - line

Make sure line ends at grid centre

Side view - start from grid centre - draw line (use grid snap to obtain shown results)

Perspective view - attach two line together

Vertex mode - select 2 vertex over lapping - weld

Highlight vertices right click - change from corner to smooth or corner biezers to obtain smooth transfer where required

Turn on render - render in viewport - select radius

Apply symmetry modifier 

Adjust vertices to obtain desired results

Enter hierachy mode - affect pivot only - centre to object - turn off affect pivot only

Pivot point will now be on object centre

Add box to scene

Highlight box

Shift + a  -  click on legs  -  will align pivot point of box with legs

Adjust position and dimensions to form seat

Edge selection - apply chamfer

Apply turbo smooth to test if geometry holds with chamfer

Add extra geometry as shown using connect tool

Select groups of vertices (in verticle plane) and move vertically to produce results as shown

view results by enabling turbosmooth

Copy seat piece of geometry

Re-position  and re-shape as shown

Render tested to check visual appearance

Decided to re-shape legs as shown

Import chair to table folder

Position at angle to sit under table - copy - position to sit adjacent - increase copt number

Group chairs - apply symmetry modifier

Position accordingly

Due to rotation applied to back rest of chairs on creation and selection method of group - guide incasement (box that surrounds geometry) is slanted to angle and projected in symmetry - will not effect model due to application but if were used for animation would require addressing

Apply same materials to chairs (table legs ~ chair legs - table main ~ chair seats)

Test render
