The grid is defined by coordinates in 3D space. It is shown two-dimensionally on the view plane by dash-and-dot lines. A grid can be rectangular or radial.

It is possible to have more than one grid in a model. For example, a large-scale grid for the entire structure, and smaller grids for some detailed sections.

It is also possible to show grids and grid line labels in drawings, and to modify how they are shown in the drawings.

visualization with DirectX renderingprocess of making the model object faces visible

The rendered model object faces can be transparent or non-transparent

has been improved for reinforcing bars, handles, and stick representationthe way that the information included in a model is represented visually

:

  • Curved rebars are not anymore shown with a stick line in certain zoom levels.
  • Highlighting for thin rods now always appears.
  • In rebar set: selecting a modifierline or polyline that can be used to locally modify reinforcing bars in a rebar set

    Rebar set modifiers can be rebar set property modifiers, end detail modifiers, or splitters. Also rebar set secondary guidelines behave like rebar set modifiers.

    Polyline modifiers may have corner chamfers. Each rebar set modifier only affects those rebar set reinforcing bars that its projection touches.

    does not change the visibility of the unaffected bars.
  • Rebars do not disappear when zoomed to closely from the top/front angle.
  • Snap symbols are the same size in DirectX rendering than in OpenGL.
  • Changing the rendering mode now works after redraw.
  • Parts change color after redraw.
  • Visualization of parts is not affected by redraw in the Ctrl+1 mode.
  • DirectX rebar representation is now correct after rebar creation.
