Material Properties

Logistics > Material Properties

Define the available materials and the properties for each material. Up to 60 materials can be defined.

Materials table

Each row in the table defines a material. The material properties are defined in the columns of the table. The following properties can be defined for each material:

  • Material code – The abbreviation used for the material type, with a maximum of six characters. An undefined material code can be specified by selecting Not specified.

  • Specific gravity – The relative density of the material. For an undefined material code, a negative value can be defined.

  • Bending code – The bending code for the material. This value is optional.

  • Pen number – The pen number used for the presentation of the part having this material type.

  • Thickness – The threshold for plates to be drawn with a hatch or a colour fill pattern. When the thickness of a plate is smaller than the entered value, the plate is presented with a default double line presentation.

    It is possible to set this threshold also with the Maximum plate thickness for lines setting in the Drawing Properties > Visibility dialog in the 3D-Contek application. The system will use the setting with the lowest threshold, and the other setting is ignored.

  • Fill type – Defines the fill type. The available types are Hatch and Colorfill. You must specify a pattern number next to the type.

  • Model name – The name of the model (located in the %ncgmodellen% directory) that is used for the presentation of the material type. This value is optional.

  • Part breadth – Defines the breadth of the part having this material type. If the part in cross section has a size between 95% and 150% of this breadth, the model is used for the presentation. Otherwise two lines are used for the presentation. This value is optional.

  • Insulation – Yes in this column indicates that the material is used as an insulation material.

    • To set an exixting material as an insulation material, select the material and the Insulation check box, and click Modify.

    • To create a new insulation material, define the properties as desired, select the Insulation check box, and click Add.

    • To set an insulation material as a non-insulation material, select the material, clear the Insulation check box, and click Modify.

Default material code

One material can be defined as the default material. To do this, select the material and click Set as default. The default material is indicated by the text (default) next to the material code.

Missing material type

If a material type is assigned to a construction part, but the material type is not defined here (anymore), then a specific gravity of 7.85 is used, if this value is required. To override this value, add a special "absent" (=missing) material type by adding a line, and then selecting Not specified. You can set the properties for this special material type in the same way as for any other material type.

By setting a very low or very high specific gravity, parts whose weight is not in the normal weight range can indicate a missing material type definition.

Material types for profiles and shell frames

For profiles and shell frames, material types are defined by the Logistics > Profile Material setting. The first material type in this setting is used as the default material type. If no material type is defined, the default material type is determined by the default material for plates and brackets. See Profile Material.

Hull Viewer

For Hull Viewer, pen numbers for plate and profile material types are defined separately in Extra > Hull Viewer > Pen Numbers > Plate Material Pen, and Extra > Hull Viewer > Pen Numbers > Profile Material Pen, respectively. See Plate Material Pen and Profile Material Pen.
