> 3-D Grid

Grids are an important construction aid for 3-D design.

The properties of a 3-D line grid:

The grid line can have different distances in x- and y-direction. Different distances between 2 grid lines of one direction are also possible.

The grid can be placed anywhere in the drawing.

The intersection points of the grid lines are isolated points. You can access these points with the point option J.

3-D grids can contain of several layers (planes).

The Grid dialogue window is displayed to enable you to configure steel engineering grids.

Options and Buttons
Number	Number of grid lines in x-/y-direction
Distance	For even axis distances, enter the distance between the axes in the Distance field. If you want the distances between the axes to be uneven, you can enter the values directly into the table on the right-hand side of the window.
Axis annotation	An axis annotation will always be created; if the checkbox has been activated here, you can enter a start value for a consecutive axis annotation. If you do not want the axis annotation to be consecutive, deactivate the checkbox and enter the axis annotation directly in the table on the right hand side of the dialogue window.
Planes	3-D grids can consist of several planes. Specify the Number of planes and the Distance between each of the planes.
Projection	This value determines how far the grid lines will project beyond the border of the grid.
Line parameters	Click this button to specify the parameters for the grid lines. The Line parameters for 3-D grid dialogue window will be displayed, enabling you to select the colour, line type and layer of the grid lines.
Text parameters	Click this button to specify the text parameters for the axis annotation. The Text parameters dialogue will be displayed, enabling you to select the colour, layer size, font etc. of the axis annotations.
Save	Click this button to save the current grid settings. The data is saved in the HiCAD subdirectory Makro 3-D/Raster under the specified name with the extension .RST. The RST files can be reused at any time – even for other steel engineering constructions.
Load	Click this button to load a saved 3-D grid (.RST).

Options and Buttons

Number

Number of grid lines in x-/y-direction

Distance

For even axis distances, enter the distance between the axes in the Distance field. If you want the distances between the axes to be uneven, you can enter the values directly into the table on the right-hand side of the window.

Axis annotation

An axis annotation will always be created; if the checkbox has been activated here, you can enter a start value for a consecutive axis annotation. If you do not want the axis annotation to be consecutive, deactivate the checkbox and enter the axis annotation directly in the table on the right hand side of the dialogue window.

Planes

3-D grids can consist of several planes. Specify the Number of planes and the Distance between each of the planes.

Projection

This value determines how far the grid lines will project beyond the border of the grid.

Line parameters

Click this button to specify the parameters for the grid lines. The Line parameters for 3-D grid dialogue window will be displayed, enabling you to select the colour, line type and layer of the grid lines.

Text parameters

Click this button to specify the text parameters for the axis annotation. The Text parameters dialogue will be displayed, enabling you to select the colour, layer size, font etc. of the axis annotations.

Save

Click this button to save the current grid settings. The data is saved in the HiCAD subdirectory Makro 3-D/Raster under the specified name with the extension .RST.

The RST files can be reused at any time – even for other steel engineering constructions.

Load

Click this button to load a saved 3-D grid (.RST).

If you have made the desired grid settings, choose OK to exit the window. HiCAD displays a preview of the grid.

To position the grid exactly:

Choose a fitting point on the grid.

Specify the position of this point in your drawing. If you want to place the grid in the origin of the coordinate system, press the right mouse button twice.

You can define so-called Grid sub-systems to refine the structure of 3-D grids or a Steel Engineering grids. Different sub-systems can be created on the various planes of the grid, and can also run diagonally to them. A grid sub-system consists of a start point and an end point and is represented as an edge. Along this refined grid, constructions can be erected, and the corresponding beams can be placed. You can find the function in the context menu for grids. You open the context menu by right-clicking the grid

Please note:

The grid is inserted into the 3-D part structure as a main part (Type = dummy part)

called Grid. For each level of the grid, a sub-part named Grid (Type=part with free edges) is assigned to the main part.

The isolated points for the grid line intersections are only displayed and can only be identified if the representation of isolated points has been activated. You can access this function via Drawing > Visualisation > Hide/Show, Via element type

. Here, the Isolated points checkbox needs to be active.

A drawing can contain several grids.

If you want to apply changes to a grid, e.g. if you want to move it, right-click the grid and select the appropriate function in the context menu. To change the grid settings, select the Change parameters function.

The annotation of 3-D grid axes will not be shown in cut-outs, sectional views and detail views. In all other views the visibility depends on the viewing direction to the respective view, with a limiting angle of 5°. This means that if the direction vectors of the 3-D axes deviate less than 5° from the normal vector of the view (e.g. in front view or side view), the annotations for these axes will not be shown in this view, as they would otherwise intersect. As the visibility of the annotations must be set for each individual view, the annotations can only be assigned to the existing views. If new views are created, the annotations of existing grids will initially be hidden in these views. The information as to whether the annotations in this view should be shown will only be available after a recalculation of the grid. Therefore, annotations (if any) which were previously hidden can only be visualised after recalculation.

On the Steel Engineering tab, select Further functions > Settings > Grid annotations to annotate the grid axes individually. In addition, you can apply the 3-D dimensioning functions to grids if desired.
