Modeling - building - exterior - details - Windows

Highlight single vertical beam and single horizontal beam - hold shift and drag to duplicate

(unnessasry however since simple geometry is required this can be a good time saving shortcut

Duplicate these beams and position around window frame (add more then sufficient depth as this can be corrected later)

Create plane - position over window panel - alt x to make see-through
Covert to editable poly

Apply connect (highlight top and bottom edge in edge mode - connect tool)

Increase segments to cover all vertical geometry

Repeat to cover vertical geometry

Add depth to geometry (shell or highlight entire plane and extrude)

Highlight all created squares (segments) - BOTH sides

Apply inset

Remove inset geometry only

Bridge gaps (aiming to create solid window frame geometry) - edge selection mode - highlight opposing single edges - bridge tool

Repeat until all gaps are filled

Add single plane of geometry (to be used as glass when material is applied later)

Clone window segment to cover all four window planes

Copy vertical beam - horizontal beam - window segment

Align to window using scale tool

Size to fit window and repeat window segments as required

Some window frames only require four segments instead of 5
Isolate window fame geometry (copy as new geometry to manipulate) - alt + q = isolation mode

polygon mode - highlight bottom set of window frame segments - delete

boundary tool - highlight newly formed hole boundary - cap
Scale new frame and window to fit as before

Align windows with walls (worry about outside only at this point)

Create windows for opposing side of building

Align with wall as before

Create layers for windows so can be hidden and frozen as required

Not all windows in project have square segmented windows

Create plane to span window - alt + x to make see through - increase segment amount to create segments with sizes comparable to grid pattern

Alt + q = isolation mode
Alt + x = remove see through

Highlight alternating ring geometry as shown

Apply chamfer - increase size until geometry lines are about to touch (intersect)

Vertex mode - select vertices on top half (triangles) to lower vertically until diamonds are nearly created (place vertices very close to each other)

Shrink intersecting gaps until diamonds are next to each other

Repeat until geometry is collapsed to form diamond grid

Highlight rows of vertices placed next to each other
Apply weld - change threshold if necessary
This will create actual diamonds in intersecting grid

Edge selection mode - remove unwanted horizontal geometry

Raise / lower the top / bottom edges
Weld as before

Apply lattice - alter settings until desired result is obtained (4 sides, single segment .5 radius)

Rotate 90'

Turn of lattice
Use cut tool add geometry lines to incase required amount of geometry (number of diamonds)

Highlight all other geometry

Remove all other geometry

Turn lattice back on

Turn isolation mode of and align frame to window

Copy frame to cover  entire window space
Copy windows frames to cover next window

Repeat to over all windows as required
Create frames for windows as before

Align with wall

Add planes to be used as windows

Make see through to alter size as before if required

Place over frames

Since geometry is narrow can intersect frames (place in middle) to create appearance of glass

ADDED NOTES............

Applied chamfer to all window frames - highlight entire frame - chamfer - build method allows for desired results obtained through full chamfer
