Direct modeling CAD systems (SketchUp) can be made more precise and predictable by adding some facility for parameterization, this technique is called: Variational Direct Modeling

http://www.ledas.com/pdf/VariationalDirectModeling.pdf

For an even broader overview of why variational direct modeling is a way forward: Direct Modeling - Who and Why Needs It? A Review of Competitive Technologies

A potential open source direct modeling CAD application should have this feature.

Researching the implementation of an Operational Transform web based CAD system.

Purchased a copy of this paper: Operational transformation for dependency conflict resolution in real-time collaborative 3D design systems

Which discusses a few specific OT functions necessary to deal with graphs of dependent objects, essentially this resolves some issues related to multiple people editing inter-dependent parametric data at the same time and how to merge conflicting operations.
