How to obtain a conic surface in Creo Creo point cloud fitting conic surface operation process

In Creo, obtaining conic surfaces is a common task. Scanned data can be converted into editable surfaces by fitting conic surfaces to point clouds. PHP editor Baicao will take you step by step to understand the process of fitting conic surfaces with point clouds in Creo to help you process scanned data efficiently. Read the details to learn how to select point cloud data, define fitting parameters, and generate conic surfaces.

1. Open the part model where the point cloud is to be fitted into a conical surface. We will use the conical part point data in the input point cloud in the model to fit a conical surface.

2. Click and expand the [Surface] overflow menu from the [Model] tab, select [Reshape], open the Reshape tab, click and expand [ Curve] drop-down menu and select [On Facet].

3. Then move the cursor above the cone shape of the point cloud data and start selecting multi-faceted points continuously to form a closed curve, as shown in the figure below.

4. Use the same method to create another closed curve below the cone, as shown in the figure.

5. Click [Create Domain] and then move the cursor between the two curves created above to select a polyhedral point. The software will automatically create the point between the two curves. into a point domain, as shown in the figure.

6. Click and expand the [Analysis Surface] drop-down menu and select [Cone] to open the Cone dialog box, click and select the [Domain] option, and then select the just created area.

7. The software will automatically fit a cone-shaped surface based on the selected point domain, and at the same time display the key parameters of the cone surface in the dialog box.

8. Click [OK] to close the dialog box to complete the fitting, obtain the cone-shaped surface, hide the point cloud, and you can see the fitted cone as shown in the figure.

Notes

To use point clouds to fit the basic surface shape, it generally needs to be done through the point domain

Generally speaking, fitting The larger the basic shape point cloud data included in the conjunction domain, the higher the accuracy of the fitting.
