Hullforms must meet several high-level requirements for NPT (non-procedural thickening) and ACIS detailing. The following table summarizes the requirements for hullform models used in Smart 3D.

Description

Checking and Repairing

Smart 3D

Inward- pointing normals

You can visually check the normals in the graphic view. To view the normals, you can use the Show Normals.

In addition, you can use the Process Geometry Data to check and repair the normals. To check the normals, use the Outward Normals option on the Check Settings Dialog Box, and to repair the normals, use the Orient Normals option on the Repair Settings Dialog Box.

Smart 3D

Single lump sheet-body

You can visually check the sheet-body in the graphic view.

In addition, you can use the Process Geometry Data to check for multi-lump bodies. On the Check Settings Dialog Box, use the Multi-lump Bodies option.

Smart 3D

Double-sided sheet-body

You can visually check the sheet-body in the graphic view. If the sheet-body is double-sided, you can see both sides of it when you rotate it. If it is not double-sided, one side disappears when you rotate it.

Convexity errors should be avoided, but are allowable in early design.

Use the Process Geometry Data to check the continuity. On the Options Dialog Box, you can set the Acis check level.

NPT

Non-planar patch edges aligned

You can visually check the patch edges in the graphic view.

You can also use the Process Geometry Data. The Check Settings Dialog Box provides the Non- Aligned Edges option.

NPT

Uniform control point mesh size for non-planar patches

You can visually check the control point mesh in the graphic view.

You can also use the Process Geometry Data. The Check Settings Dialog Box provides the Non- Uniform Control Points option.

NPT

Only planar "trimmed" patches supported

You can visually check the patches in the graphic view.

You can also use the Process Geometry Data. The Check Settings Dialog Box provides the Trimmed Non- Planar Surfaces option.
