house/garden/site sketch plan drawing tools and drawing plan for lean-to roof or gazebo in back garden .. and BUILD May 2022

openscad is a bit head melting drawing 3d shapes .. but interesting ...

In ubuntu sudo apt-get install openscad
# I had to get my opengl to work (accelerated 3D library and drivers)
The cheatsheet and online help are useful while learning it and programming:


Also sketchup was interesting. No install needed. Runs in browser:
No programming interface so at first learning how to move camera and draw stuff takes time.

October 2022 garden lean-to build

See In google photos (PRIVATE to my Family (Sorry/NOT sorry :-7)
Sun 6 Feb 2022 
6 Feb 2022 perspective view from side of possible pergola and lean-to (North(house) is left)
 
6 Feb 2022 plan view (overhead) of back garden, measurements of paving by house and ideas for pergola/roofing cover at back of garden (North is down)


6 Feb 2022 perspective view of existing garden and ash tree with existing paving, showing wall heights, North is to left


Feb 6 2022 perspective view of existing garden with tracing paper overlay showing prospective gazebo and lean-to, North is left


May 2022 more diagramming:

side elevation and plan of simple lean to by house, North is down, East is left


BUILD: 15 Oct 2022 concreted in foundation under slab and bolt down post holder. Measure and cut frame pieces and oil/varnish.

Post holder bolted down on slab we lifted and put concrete foundation under, concrete(Post10) also used to re-grout slabs. North is bottom right.

Frame spars and light roof spars measured and cut to size and treated.

BUILD: 22 Oct 2022 Cutting and connecting frame to walls and together

Frame basic crude jointed together and screwed, bungee cord just holding unattached spars for measuring. North/West is left.

It rained a bit. Covered the new frame with old gazebo cover.

BUILD: 29 Oct Jointing and adding roof spars to frame.

Full Frame and roof spars nearly together. Supported by walls on 2 sides and post. North is left.


BUILD: 31 Oct corrugated transparent perspex screwed onto roof with help of Kate's hand drills, real drill fell in water bucket! Rainy day not ideal. Kate helped me. Yoga mats and need to go very gently on top of the roof. Finished in the dark. NOTE FOR FUTURE: try and pull the very thin and light sheets away tightly and screw down tight. On edges now we keep some sandbags to help stop wind cracking plastic (2 years later Feb 2024).

Screwing on transparent corrugated perspex. North is right.
