Create cylinder to be used to create drain pipe

Extend profile to cover base section of pipe

Copy or create cylinder of equal diameter

Apply bend modifier to cover first 90'of bend

Adjust size to fit purpose

Copy and rotate to create second bend

Attach top segment if required

((Try to leave gap between each piece))

Attach segments to main pipe

Remove end caps of geometry pieces

(this could have been performed more easily upon separate pieces)

With end caps removed - weld exposed edges together to create single pipe

Adjust single pipe geometry if required to fit profile

PIPE HOLDER

Create cylinder

make sure outer diameter is greater then pipe

Alt + q = isolation mode

Add end cap segment (2) - convert to editable poly - edge selection - select loop (inside edge geometry segment - scale out as shown

Polygon selection mode - select all polygons as shown to leave arch

Delete highlighted geometry

Bridge sections INDIVIDUALLY to maintain arch

cap ends of arch

edge selection mode - Connect tool - add 2 lines of geometry as shown - use pinch to narrow position

Highlight newly created segments

Extrude - as group - local normal

highlight back profile as shown

Extrude - group - local normal

Exit isolation mode

highlight newly created object - shift + a - left click on pipe

This will align holder pivot point to pipes pivot point - side both cylinders will place holder around main pipe

Adjust diameter and extrusion depth to fit purpose

Rotate to represent fixing to wall

Create new layers to hide pipes

Copy pipe geometry

Place one new pipe to fit into corner

Add connect lines on pipe hight

Adjust holder height

Line up connect line to allow height to be effectively trimmed

Enter isolation mode - highlight all polygons above connect line

Remove geometry

Move pipe over extruding geometry of side wall

Rotate 180'

Trim as before (but opposite) to gain result as shown

Highlight and remove geometry as shown to leave most of single bend

This will leave pipe hollow and 2 dimensional on inside as shown

Apply shell to pipe

Make sure inner amount is applied but outer amount is reduced to 0.0

Adjust height so not to overlap with roof

Copy another pipe

Move to back face of building

Slide holders down into position

Trim using techniques as before to create small side pipe
