Create frames and slopes

A frame is a 2D view of the model, created in a vertical plane defined by an existing grid line. Since only the members that lie within the plane of the frame are displayed, a frame view can be particularly useful for defining bracing.

A slope is a 2D view of the model, created in an inclined plane. You can define a slope by selecting 3 existing grid points. Since only those members that lie within the plane of the slope are displayed, this type of view can be particularly useful for defining inclined roofs and ramps.

Create a frame

  1. Obtain a 3D view of your model where you can see the base grid line associated with the frame that you want to create.
  2. On the Model tab, click Frame.
  3. Position the mouse pointer over the grid line for the frame that you want to create.
  4. Click to create the frame.

    A frame for the selected grid line is added to the Frames branch of the Structure tree and a rectangle is displayed in the 3D view to illustrate the frame extents.

    Tip:
    To open a 2D view of the frame:
    1. Click the + sign on the left side of Frames in the Structure tree.

    2. Double-click the name of the frame view you want to open.

Create a slope

Note:

Before creating a slope, note that:

  • In order to create a slope, you need to be able to click three existing (not co-linear) grid points that lie in the plane of the slope.

  • Grid points are formed at grid line intersections on construction levels. Therefore, if the points required to define the slope do not currently exist, you may need to insert new construction levels and grid lines to form them.

  • A sloped plane must be entirely contained within a single sub model because the sub model determines the mesh parameters to be applied.

  • In a sloped plane, positive Y is always aligned to the up-slope direction, so that positive X is always perpendicular to the slope.

  1. Obtain a 3D view of your model where you can see three grip points that define the sloped plane.
    Tip:
    If you cannot see the grid line intersections on a particular construction level in the 3D view:
    1. In the Structure tree, select the level.

    2. In the Properties window, select the Show grids in the 3D view option.

      If you wish, you can clear the Show grids in the 3D view option for other levels to simplify the display.

  2. On the Model tab, click Sloped Plane.
  3. Click the three points which define the sloped plane.

    A sloped plane is added to the Slopes branch of the Structure tree and a polygon is displayed in the 3D view to illustrate the slope.

    Tip:
    To open a 2D view of the slope:
    1. Click the + sign on the left side of Slopes in the Structure tree.

    2. Double-click the name of the slope view you want to open.

Show frame or slope references

The Show references command can be used to list all entities referenced by a selected frame or slope.

  1. Open the Frames or Slopes branch in the Structure tree.
  2. Right-click on the required frame or slope name.
  3. From the context menu, select Show References...

    All entities that are referenced by the selected frame or slope are listed in a dialog box. If entities are selected from the list they are highlighted in the 3D Structural view and their properties are displayed in the Properties window.
