Dimensional drawings · technical sheets

Every line
from one spec.

LeftBlank ships a drawing guide for agents. Give it a reference — a spec sheet, a screenshot, your own measurements — and it draws a monochrome sheet whose views, dimensions and table all come from one small dictionary of numbers.

Connect your agentTry this prompt ↓
A dimensional drawing of a shelf bracket: top, front and right-side views, a 4× slot detail, and a table of dimensions with assumptions and open items.
Rendered by Typst 0.15.1 from examples/drawings/main.typ. Select for full size.

What your agent can do

  • ViewsAligned top, front and side views; enlarged details at a stated scale.
  • DimensionsDimension and extension lines, leaders, short codes on the drawing and values in the table.
  • Traceable numbersMeasured, derived and assumed values are kept apart. Unknowns stay [TBD] rather than invented.
  • UI anatomyThe same kit draws interface components: insets, nested corner radii, layout slots.
  • RedrawChange one number in the spec and every view follows.

Read the dimensional-drawing guide, then draw a concept sheet for a steel shelf bracket: 150 mm arm, 120 mm leg, 40 mm wide, 4 mm thick, two countersunk 6 mm holes 70 mm apart, one 14 × 6 mm slot in the arm. Show top, front and right-side views and a 4× detail of the slot. Mark material and tolerances as TBD.

Paste it into your agent once LeftBlank Office is connected.

Good to know

  • The guide is an MCP resource at leftblank://guides/dimensional-drawing/guide.md, with the drawing kit and two worked sheets. Its method adapts Enes Ozturk's MIT-licensed dimensional-drawing skill.
  • These are communication drawings. A sheet is only as precise as the numbers you give it; it is not a certified manufacturing drawing.
