About Presentation

Below are some facts about presentation of exact or tessellated geometry.

Check recommended practices, licensing and application protocol requirements in Requirements.

This page discusses:

At Import

Below are some rules applied at import.

Line Types

  • The line type is taken into account.
  • If the requested line thickness is defined in your environment, this thickness is taken into account, else the nearest predefined thickness is taken.

Points Styles

Point styles are mapped as follows.

3DEXPERIENCESTEP


cross, triangle
plus
circle
square
asterisk
dot

Colors

  • Color exchange is supported.
  • When an entity OVERRIDING_STYLE_ITEM exists in the STEP file for a given face, this color overriding is taken into account: The color of the face is overridden.

Transparency

Transparency exchange is supported by exact and tessellated geometry.

For exact geometry:

  • The transparency of exact geometry (solids, shells and faces) is kept at import.
  • The transparency of a face of a solid can be overloaded and is kept in the STEP file.
  • The transparency set on a representation is ignored.
  • The transparency set on a body is ignored, but applied to the geometry it contains.

At Export

Below are some rules applied at export.

Lines

3DEXPERIENCE handles 7 types of line whereas STEP proposes 5 types only. The mapping is the following.

Colors

  • Colors are exported according to Requirements.
  • When the color of a given face is different from the color of its solid, an entity OVER_RIDING_STYLE_ITEM is created in the STEP file, and the face keeps the overriding color.
  • STEP limitation with assemblies: Since attributes can not be set on instances of components, the color of instances are not taken into account.

Transparency

Transparency exchange is supported according to Requirements.

For exact geometry:

  • The transparency of exact geometry (solids, shells and faces) is kept at export.
  • The transparency of a face of a solid can be overloaded and is kept in the STEP file.
  • The transparency set on a representation is ignored.
  • The transparency set on a body is ignored, but applied to the geometry it contains.
  • If the transparency of an instance in an assembly is overloaded, the transparency is ignored at export.
