Every term here is used with exactly this meaning throughout the course. Where CAD packages disagree on a word, the Onshape sense is the one given.

The fact that a printed part is weaker between layers than within them. The reason print orientation is a design decision.
Taught here →What a feature does with its result: new part, add to an existing one, remove from it, or keep only the intersection.
Taught here →A flat span printed across open air between two supported ends. Clean under about 5 mm; sagging beyond that.
Taught here →An angled cut edge. Self-supporting when printed, which is why it is the right choice on any edge facing the build plate.
Taught here →The gap deliberately designed between two mating parts, quoted per side. A diameter needs twice the per-side value.
Taught here →A mechanism for generating variants of one model — sizes, options — without duplicating the Part Studio.
Taught here →A geometric rule between sketch entities: coincident, horizontal, tangent, equal, concentric, symmetric. Removes degrees of freedom without naming a number.
Taught here →An unknown the sketch solver has not yet been told. Each sketch point carries two — an x and a y. A line segment starts with four.
Taught here →The relationships a model encodes about what must stay true — which dimensions move together, what each feature is measured from. Lives in your references and constraints, not in comments.
Taught here →A numeric value applied to sketch geometry. Also removes degrees of freedom — the difference from a constraint is that it fixes a size rather than a relationship.
Taught here →The bulge at the bottom of a print where the squashed first layers spread. A small chamfer on the bottom edges makes it irrelevant.
Taught here →Push a flat profile along a straight line to make or remove material. The default verb of solid modelling.
Taught here →How wide a bead of plastic the nozzle lays down — close to, but not identical to, the nozzle diameter. Walls should be whole multiples of it.
Taught here →Fused deposition modelling — the layer-by-layer molten filament process almost every desktop printer uses. Every design rule in this course follows from it.
Taught here →One operation in that list — an extrude, a revolve, a fillet, a variable. Features are editable after the fact and execute in order.
Taught here →The ordered list of features. It is the program that produces the part, and reading it top to bottom should describe how the part is made.
Taught here →A rounded edge, applied as a feature. Structural in loaded inside corners; an overhang problem on downward-facing edges.
Taught here →A dependency on a face or edge that a later edit can rename or destroy, causing downstream features to fail. The usual cause of a red feature tree.
Taught here →Zero degrees of freedom remaining. The sketch has exactly one possible shape and nothing in it can be dragged. Onshape draws it black rather than blue.
Taught here →A shape stored as a set of triangles, with no record of how it was designed. STL files are meshes; they are an output, never a source of truth.
Taught here →The permanent point and three planes every document starts with. The most durable thing to anchor geometry to, because no edit can delete them.
Taught here →More constraints and dimensions than the geometry has freedom for, usually because the same fact was stated twice or two facts conflict.
Taught here →A surface leaning out over nothing, measured as an angle from vertical. Beyond roughly 45° it needs support.
Taught here →A modelling approach where the file stores the ordered operations that build the shape, plus the numbers driving them. Editing a number replays the operations and rebuilds the part.
Taught here →Onshape name for the modelling environment. One Part Studio can contain several parts that share a coordinate system and variables — the right place to model things that must fit each other.
Taught here →Assembles with force and stays; assembles by hand and holds; moves freely. Roughly increasing clearance, with the actual values measured from your own printer.
Taught here →Flat 2D geometry on a plane or face, used as the profile for a 3D feature.
Taught here →A depth option meaning "as far as there is material", rather than a typed number. Keeps a hole a hole when the part gets thicker.
Taught here →How much a dimension is permitted to vary from nominal. A property of the process, not something you choose.
Taught here →A named value usable in any dimension field, written #name in Onshape. Turns a repeated number into a single stated fact about the design.
Taught here →Every claim on these pages links to its source. If a source looks wrong or out of date, check the resource list and tell your teaching agent — the course is meant to be corrected.
