How to Measure in SOLIDWORKS

The Measure tool in SOLIDWORKS lets you check distances, angles, edges, faces, circles, arcs, coordinates, and clearances without adding permanent sketch dimensions. It is one of the fastest tools for inspecting a model, checking imported geometry, confirming a fit, or answering a quick manufacturing question.

You can use Measure in parts, assemblies, and drawings. The exact information shown depends on what you select: points, edges, faces, bodies, components, arcs, or a combination of entities.

Open the Measure tool

1. Open the part, assembly, or drawing you want to inspect.
2. Go to the Evaluate tab.
3. Click Measure.
4. Select the geometry you want to measure.
5. Read the values in the Measure dialog and the graphics area.

Measure distance between two items

To measure a distance, select two points, two edges, two faces, or a useful combination such as a face and an edge. SOLIDWORKS displays the distance between the selections. In assemblies, this is a quick way to check clearance between parts before you create or edit mates.

If the result does not look like the distance you expected, check what is actually selected. A face-to-face measurement, point-to-point measurement, and edge-to-edge measurement can all return different values for the same area of a model.

Measure angles

To measure an angle, select two non-parallel lines, edges, planes, or faces. SOLIDWORKS shows the angle between them. This is useful when checking drafted faces, bracket bends, sketch relationships, or imported geometry that may not have clear feature history.

If an angle result is missing or confusing, clear the selection and choose cleaner references. Temporary axes, reference planes, and straight edges often make angle checks easier than selecting complex faces.

Measure circles and arcs

When you select circular edges or arcs, the Measure tool can show values such as diameter, radius, center distance, minimum distance, and maximum distance depending on the selection and options. This is helpful for holes, shafts, clearance checks, and curved profiles.

For hole-heavy drawings, you may also want to use a formal table instead of manually checking every hole. See how to create a SOLIDWORKS hole table when you need drawing documentation rather than a quick inspection.

Change units and precision

The Measure tool can display values in different units without changing the model document units. Use the units or precision controls in the Measure dialog when you need to check a metric part in inches, compare supplier data, or round values for a quick review.

Do not use a rounded Measure value as a final manufacturing dimension unless it matches the drawing or model intent. For released work, dimensions and tolerances should come from the drawing, model annotations, or controlled design data.

Measure in assemblies

Assembly measurements are useful for checking clearance, envelope size, hardware fit, and movement limits. Select faces or edges on different components to measure the distance between them. If a component can move, make sure the assembly is in the position you actually want to inspect.

For fit checks, the Measure tool and Interference Detection work well together. Measure shows distance and clearance; Interference Detection tells you when components overlap. If you are checking a mechanical assembly, also review how to use Interference Detection in SOLIDWORKS.

Common mistakes when measuring

• Selecting a decorative edge instead of the design reference edge.
• Reading a rounded value as if it were the exact design dimension.
• Measuring an assembly while a component is underdefined or in the wrong position.
• Using Measure when a drawing dimension or tolerance should control the answer.
• Forgetting to clear selections before starting a new measurement.
