Problem

When you import long range scan data such as a building, a huge statue, a ship and so on, the origin of these data may be far from global origin of the application. Thus you may not normally work with these scan data in the application. One of problems is that you cannot create solid or surface body which is very far from global origin because of Parasolid limitations.

You can see the mesh data is positioned very far from global origin by creating a Ref. Point on the mesh such as shown in the image below.

If you try to create a surface using Extrude,

You cannot see the extrusion surface in the graphic window, even if it is registered in the Model and Feature Tree.

Solution

• When your imported scan data is very far from the global origin, you will be warned with the following message: “The center position of imported data is too far…”.

• After importing scan data, move the scan data to origin (0, 0, 0). Execute Tools > Align > Interactive Align command. Check the Pre-align With Global Origin and go to the next stage.

• Click OK. The mesh data is moved to the origin.

• Create the extrusion surface in the same way as before.

• Now you can see the extrusion surface without any problem.
