A work task model created on the physical modeling surface.
virtual surface and explicit interface
before placing a block, register it's label
registering the label by using the explicit interface
new label has been recognized
align label, then register it to use it for modeling
stating modeling a few blocks
using connectors
process model on virtual surface is kept synchronous
continuing modeling ...
...
... using labels to identify blocks
closeup view of an activity block
open activity block
registering an artefact
putting the artefact into the block
artefact is now contained in the activity block

finished model on pyhsical surface
