Level Symbols

Level symbols are auxiliary objects used to identify the elevation of a point according to a reference level (height), often the sea level.

Using level symbols

Level symbols are placed in the model to identify level dimension points. The level symbols placed in the model can be taken into account at drawing creation using an adequate drawing style. When modifying the reference level, in the details, the level dimensions are automatically updated.

Example

Using level symbols you can define a global reference level that can be added to all measurements so that the model may be kept at the AutoCAD WCS.

Note: All level symbols in a model share the same reference level.

For a leveled structure, you can place a level symbol at each floor level.

Representation

The level symbols are represented in the model as red arrows. You can modify their size in the level symbols properties dialog box.

Insert a level symbol

Inserts a small symbol into the model to identify the correct height at the selected reference point.

To access the command

Ribbon: Objects > Grid:

Command line: _AstM4heightkote

To create a level symbol

1. On the Objects tab, Grid panel: Click .
2. Define the insertion point for the level symbol.

• The level symbol is created. The Properties dialog box appears.

To define the reference level

1. Select the level symbols. You can use one of the selection methods.
2. Right click and select Advance Properties from the context menu.
3. On the Global tab, define the global reference level (the global height of the AutoCAD WCS origin).

Note: All level symbols in a model share the same reference level.

To switch off the level symbols

1. Select the level symbols to hide. You can use one of the selection methods.
2. Right click and select Advance Properties from the context menu.
3. On the Display type tab, select Off .

• The level symbols are hidden.

To change the symbol default size

1. Select the level symbols. You can use one of the selection methods.
2. Right click and select Advance Properties from the context menu.
3. On the Default tab, enter the desired size for the symbol.

• The size of the selected symbols changes. Newly created symbols will have the new size, by default.
