Share your SOLIDWORKS window and say what's wrong. Cadet reads the FeatureManager and your brief, then points at the next click — you make it.
Your gearbox assembly has a rebuild error. Here's your plan:
SOLIDWORKS help
The SOLIDWORKS problems students get stuck on — and the fix
A red X or yellow triangle in the FeatureManager means a feature can't rebuild. Right-click it → What's Wrong. Usually a sketch lost its reference (an edge or face you changed), so fix the dangling dimensions and relations (Display/Delete Relations) and rebuild with Ctrl+Q.
Red mates or a (+) in the tree mean the assembly is over-defined; a component marked (f) is fixed and won't move. Use MateXpert to find the conflicting mate, delete it, and right-click → Float for parts that shouldn't be fixed.
The contour is open or crosses itself. Tools → Sketch Tools → Check Sketch for Feature finds the gap or overlap; Repair Sketch fixes small ones. To extrude only part of a sketch, pick the region in Selected Contours.
The radius is too big for the geometry next to it. Try a smaller radius, fillet the larger edges first, or use FilletXpert to find which edge is the problem.
Blue lines are under-defined, black are fully defined. Add relations (Horizontal, Coincident, Tangent) and dimensions, anchor the sketch to the origin, or use Tools → Dimensions → Fully Define Sketch.
Evaluate → Interference Detection lists every overlap between components. Use Clearance Verification for minimum gaps, and fix the mates or dimensions that cause each one.
File → Make Drawing from Part, drag in the standard views, then Insert → Model Items to bring the model's dimensions across. Add section and detail views, and fill in the title block in the sheet format.
Right-click Material → Edit Material to set it, then Evaluate → Mass Properties. Check the units under Document Properties → Units so the mass matches what the brief asks for.
SOLIDWORKS can't open files saved in a newer release. Use the same version as your lab, or ask for a STEP file, which opens anywhere (without the feature history).
Every instance must still be valid geometry. Check the axis or direction you picked, reduce the count or spacing, or switch to Geometry pattern for simple features.
In the ConfigurationManager, right-click the configuration → New Exploded View, then add steps by dragging components. Animate it with Animate explode, and show it in a drawing view through the view's properties.
Open it with components Lightweight or in Large Assembly Mode, suppress parts you're not working on, and turn off RealView and shadows.
It needs sheet metal features (Base Flange) or Convert to Sheet Metal, with one consistent thickness. Then use Flatten in the Sheet Metal tab.
