Overview

Nexus can create and modify geometry directly in SolidWorks — sketches, features, surfaces, and assemblies. You describe the shape and intent; Nexus handles the feature tree. This is useful when creating geometry from a specification, making systematic edits across many features, re-parameterising existing models, or applying changes that are tedious to perform manually.

​
What Nexus can help with

  • Part modelling — Create bosses, cuts, fillets, ribs, shells, sweeps, lofts, and complex surfaces from a written description.
  • Parametric editing — Change dimensions and relationships across an entire feature tree without opening each feature individually.
  • Assembly management — Add, suppress, or reorder components; create and update mates; run interference checks.
  • Configuration and variants — Generate a family of parts (small, medium, large) from a master model, or create a simplified body for simulation.
  • Import and repair — Import STEP/IGES files and repair common translation issues (missing faces, open bodies, duplicate geometry).

​
Example prompts

Create a new part: a rectangular base plate 120mm x 80mm x 6mm. Add four M6 counterbored holes at each corner, 10mm from each edge. Add a 2mm fillet on all top edges. Set the material to Aluminium 6061-T6.

In C:/Projects/Bracket/bracket_v3.SLDPRT, change the boss diameter from 20mm to 25mm. Then update the clearance hole in the mating part at C:/Projects/Bracket/clearance_plate.SLDPRT to match, with 0.5mm clearance.

Open C:/Projects/Pump/pump_asm_v2.SLDASM. Suppress all fasteners (screws, bolts, washers, nuts) and hide the housing body. Take a screenshot of the exposed internal components.

From the current master part, create three configurations named Small (scale factor 0.8), Standard (as-is), and Large (scale factor 1.25). Save each as a separate SLDPRT file in C:/Projects/Family/.

Import C:/Incoming/housing_supplier.step and check it for translation issues. Report any open bodies, missing faces, or duplicate geometry. Attempt automatic healing and confirm the resulting body is solid.

Tips for geometry prompts

  • Reference features by name — “The Base-Extrude feature” or “the M8 tapped hole pattern” is more reliable than “the first boss” when editing existing models.
  • Specify the plane — For sketches, say “on the top face” or “on the Front plane” to avoid ambiguity.
  • Use relative positioning — “10mm from the edge”, “centred on the face”, “offset 5mm from Datum Plane 1” — Nexus understands spatial language.
  • State current state — If modifying an existing part, briefly describe the relevant current state if it’s not obvious from the file name or context.
