Okay. You want to make a series of bamboo columns and framing pieces to start. For a bamboo pattern like your bamboo board, you make that like any other texture using a flat, full on seamless picture. Study any textured material [like brick] and imagine substituting a picture of a bamboo wall in there instead.
Making textures involves getting an appropriate image and sizing it in the material dialog.
For 3D bamboo framing: Archicad has a problem doing this and it is, therefore, an intermediate skill level challenge.
You'll use several tools:
The COMPLEX PROFILE
to define the contour of the bamboo shape from top to bottom.
complex profiles wiki article
and - for creating vertical bamboo, the WALL TOOL.
Draw a small circular wall using a complex profile, similar to a revolve in creating a circular section. Now you have a bamboo......
To tilt the bamboo for braces is trickier:
The bamboo column created with the complex profile and wall tool must be saved as an OBJECT, then again as a special Archirotate object using the free Cigraph tool ArchiRotate to tilt it.
