SOLIDWORKS part

CAD & 3D

SLDPRT is a SOLIDWORKS part with geometry and design information. Use compatible eDrawings for viewing or SOLIDWORKS for editing. Check versions, dependencies and configurations when it fails on another PC.

Example: a practical checking sequence

Example: ask a manufacturer whether it needs native features or only geometry/dimensions. Check the receiving CAD version, export a suitable form, and verify dimensions and holes. Specify configurations. Viewer success is not proof of native feature editing.

Opening steps

Choose your environment or purpose to see its steps.

Edit in SOLIDWORKS

Compare producing and receiving versions first.

  1. Copy the source and external references.
  2. Open in a compatible version and inspect warnings and the feature tree.
  3. Check configuration, units and dimensions; save separately.
View in eDrawings

A viewer does not provide full CAD editing.

  1. Check eDrawings format and version support.
  2. Open SLDPRT and rotate to inspect geometry.
  3. Check edition and document permissions for required features such as measurement.

Menu labels and support vary by app, OS and version. Preserve the original before making changes.

Troubleshooting by symptom

  • Newer-version warning: check compatibility and request a supported export.
  • Missing geometry: check configuration and suppression states.
  • Missing dependencies: inspect derived-part and external references.
  • Neutral export lacks history: STEP does not reproduce the native feature tree.
  • STL dimensions differ: check units and mesh-export settings.

SLDPRT → STEP / STL

  1. Select the intended configuration and units.
  2. Export STEP for CAD exchange or suitably configured STL for printing.
  3. Verify dimensions, faces, holes and mesh in the receiving software.

Geometry exchange does not preserve all history or constraints; keep the native part.

Part versus assembly

SLDPRT is a part; SLDASM references components in an assembly. One part may not represent the complete assembly.

Handoff checks

Use supported collection such as Pack and Go for dependencies; arbitrary renaming or movement can break references.

  • Record version, configuration and units.
  • Identify viewing versus editing needs.
  • Verify dimensions after exchange.

Handling and security

CAD geometry and dimensions can be confidential; check access and avoid unknown online converters.

Questions and answers

Can a viewer edit the design?

Viewing is distinct from native CAD editing.

Can an older version always open it?

Check version-specific compatibility.

Does STEP preserve the whole feature tree?

It normally does not preserve identical native history.

Why do STL dimensions change?

Check units and export settings.

How do I transfer references?

Use supported dependency collection such as Pack and Go.
