Room-model coordinates and levels: keep the geometry consistent

Pick a clear origin and direction

Choose a point on the plan that is easy to identify again, then define which direction increases each coordinate. For a rectangular study, you might place the origin at a lower-left interior reference and describe positions along the plan's two axes. Record that choice in the brief. If another person uses a different origin, their values may be correct in their convention but incompatible with yours. Coordinate notes prevent that confusion.

Check position as well as size

Suppose a living room begins at x = 0 and has a width of 20 feet. A neighboring room beginning at x = 20 shares that boundary in the same coordinate convention. Beginning at x = 19 creates a one-foot overlap, even if both rooms have plausible dimensions. Check adjoining boundaries explicitly rather than relying on a zoomed-out view. Small overlaps can be easy to miss when a scene uses translucent colors.

Distinguish a floor label from an elevation

Ground floor and level one are labels; their actual vertical relationship comes from project information. Ceiling height and floor-to-floor height are also different measurements. A simple concept viewer may arrange room boxes using a convention that is not a verified building elevation. Do not infer slab thickness, stair geometry or structural relationships from that arrangement. Use sections and qualified review for questions that depend on actual vertical dimensions.

Document the tool's convention

TranslateDesign's manual editor uses feet, nonnegative plan coordinates and numbered floors. It rejects overlapping rectangles on the same floor. Its export arranges conceptual levels using a simplified height convention, not surveyed building elevations. Use floor views to review local layouts and include those limitations when sharing an OBJ. If the project's geometry cannot be represented accurately as rectangles, record that limitation instead of describing the study as complete.

• Record the origin and axis directions.
• Check shared boundaries numerically.
• Keep room height and floor elevation separate.
• Confirm units again after export.
