Share your Rhino window and say what's wrong. Cadet reads the model on screen and your brief, then points at the next click — you make it.
Your pavilion surfaces won't join. Here's your plan:
Rhino help
The Rhino problems students get stuck on — and the fix
Surfaces only join where their edges meet within the file's absolute tolerance (Document Properties → Units). Run ShowEdges → Naked edges to see the gap, close it with MatchSrf or by rebuilding the edge curves, then Join again. Set the tolerance your brief needs before you model, not after.
ShowEdges with Naked edges highlights every open edge. Tiny gaps can be closed with JoinEdge (sparingly); real gaps need the surface fixed — Untrim and re-trim, MatchSrf, or rebuild the patch with NetworkSrf or Patch. You're done when What reports a closed polysurface.
Booleans need closed polysurfaces and fail on faces or edges that exactly coincide. Check both objects are closed (What), push one slightly past the other so they overlap cleanly, and break complex booleans into smaller steps.
The curves' seams or directions don't line up. Run CrvSeam to put every seam in the same place and Dir to match their directions, then loft again — or pick each curve near the same end, and use Align curves in the Loft options.
The radius is usually bigger than a neighbouring face or a tight curve allows. Try a smaller radius, fillet in stages (largest edges first), and check for tiny sliver edges with ShowEdges. A different rail type (Rolling ball vs Distance between rails) often succeeds.
Run Make2D from a named view (Top, Front, Right or a perspective) and keep the result on its own layers. For a scaled sheet, use a Layout with detail views and add dimensions in layout space.
Check Document Properties → Units against the brief. Change the units and choose to scale the model, or use Scale with a reference distance for imported geometry.
OffsetSrf fails when the distance is bigger than the surface's tightest curvature; reduce it, or simplify the fillets first. Shell needs a closed polysurface and a face to remove; for thin walls, OffsetSrf with Solid=Yes is often more reliable.
The object must be a closed polysurface. Export Selected as .stl and use the detailed mesh controls (a small maximum distance, edge to surface) so curves stay smooth. Check the mesh with Check or MeshRepair before printing.
Turn Gumball on in the status bar. Click a Gumball arrow and type a value to move an exact distance, or use Move with Osnap and SmartTrack for point-to-point moves.
Grasshopper shows a preview, not real geometry. Right-click the final component and choose Bake (pick the layer) to turn it into Rhino objects you can edit and export.
Work in Wireframe or Shaded rather than Rendered or Arctic, hide or lock layers you're not using, lower the render mesh quality (Document Properties → Mesh), and use Blocks for repeated parts.

Cadet
£2.99
for a whole night before a hand-in — or 5 free sessions every week
A freelancer takes weeks, costs hundreds, and hands you a file you can't explain in a viva. Cadet sits with you in your own model and shows each step, so the work — and the understanding — is yours.
It shows the step; you make the click. That's why departments can recommend it.
A session is one problem, start to finish — retries are free.
£0 / forever
5 sessions a week with a daily usage allowance. Full quality, never degraded.
£2.99 / one day
For zero sessions left, inside deadline week. Credited toward the semester.
£7.99 / per month
Sessions every day, every tool, project memory. Priced where Quizlet Plus and Spotify Student already sit.
£24.99 / 3 months
The headline plan. No annual, because nobody wants Cadet in July.
Cadet also helps in SOLIDWORKS, Fusion 360, Revit and many more apps.
