Automated gridmodeling aid that represents a three-dimensional complex of intersecting grid planes or intersecting grid planes and curved grid surfaces

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.

dimensioning in cast unit and assembly drawings now only places dimensions on grid lines where objects are placed.

Export Unitechnik (79): The following options have been added on the Reinforcement tab:

  •  A new Reinforcement export type option called Designated welded bars has been added. This option works in the same way as Fabrication of welded rebars, but you can use it with the Collect based on option to designate the rebars that will form main layers with reinforcement type 1 or 2, while the rebars remain as RODSTOCK depending on object typedescription of a group of objects that share common characteristics

    The objects are grouped based on different characteristics in models and in drawings. Examples of model object types are beams and rebar sets. Examples of drawing object types are parts and marks.
