Forgecad Blockout Model

When you need to answer "does this fit" or "how should these parts relate" before committing to detailed CAD work, this skill builds rough spatial mockups from 3 to 7 simple primitives. It enforces discipline around what blockouts are for: layout, proportions, motion envelopes, and part relationships, not production geometry. The method is opinionated about naming uncertainty honestly, using transparency only for real physical volumes like sweep arcs or clearance zones, and stopping before you're tempted to add fake detail. It renders from multiple angles and includes a handoff rule that tells you when to graduate to the full parametric modeling skill instead of polishing a concept forever.
