Surface from Scattered Points

Turn measured data into a surface you can use

A scan or a set of sample points describes where a surface lies. Surface from Scattered Points helps your application turn that data into a fitted CAD surface.

Use it to rebuild a measured region, fill a bounded opening, adjust an existing surface, or improve a connection between surfaces and wireframes.

How it works

Select measured points, a suitable starting surface, and any boundary or tangent requirements. The calculation fits a smooth surface to those inputs. Review how closely it follows the data, then refine smoothing or surface detail before using the fitted result in a CAD model.

Guide fitting with points and boundaries

Provide points, boundary conditions, and tangent or other supported constraints. Use a suitable starting surface for the region being fitted.

The fitting process adjusts a B-spline surface while controlling smoothness. This gives your team a way to express both the data to follow and the shape quality needed later.

Balance fit and smoothness

A measured surface may contain noise. Smoothing, continuity, iteration, and surface-complexity controls help balance a close fit with a smooth CAD surface.

Review the distance between measured points and the fitted surface. Additional surface detail can follow complex data more closely, while a simpler surface can be easier to edit and process later.

Rebuild the region your design needs

A fitted CAD surface becomes more useful when the application knows how it will be joined to the rest of a model. Boundary position and tangent requirements help describe those connections. Selected measurement points describe the shape to follow, while smoothing controls help manage variation in the input.

Plan fitting around a meaningful region, such as a measured panel or a bounded area needing repair. Several carefully chosen regions can support a larger reconstruction process through your application’s surface-building and joining tools. Users can control the fit for each selected region and review how it joins neighboring geometry.

Rebuild a measured area for further design work

A tooling team may have measurements of a worn or modified region but no usable CAD surface for that area. Working directly from scattered points makes later editing and joining difficult. Rebuilding the entire object can add work when only one region needs attention.

A reconstruction application can select the measured area, set its boundaries, and fit a surface with the required smoothness and tangent conditions. Users can compare the fit with the points and inspect how it joins neighboring geometry. Smoothing choices help keep measurement noise from driving unnecessary surface detail.

Your application can retain the measurement set, fitting settings, and reviewed surface with the repair job. This helps design and tooling teams discuss the same reconstructed region and repeat the fit when measurements change. Joining patches and completing the usable CAD model follow through the surrounding modeling tools.

Build a reverse-engineering workflow

Choose regions and boundaries, fit surfaces, and connect them through your application’s model-building steps. Use BestFit to align measured data with an existing reference and Shape Healing & Validation for later preparation.

Bring your points and boundary requirements. We can help define a fitting workflow around continuity, accuracy, and the CAD result you need.
