![]() These drawings contain two types of automatic properties: drawing-specific and view-specific.ĭrawing-specific properties apply to the whole drawing: coordinate system, coordinate system rotation, drawing titles, drawing layout, user-defined properties, and some detail and section view properties. Single-part, assembly and cast unit drawing properties Hatch_types1.pat for setting hatch patterns. Rebar_config.inp for setting reinforcement, and Drawing settings that are defined through various options and advanced options in.You can open the drawing properties dialog boxes for setting the automatic drawing properties by going to theĭrawing properties and then selecting the drawing type. Properties can be adjusted also after you have created the drawing. When creating a new drawing, always start by loading automatic drawing properties that you think contain the best settings for the drawing you are creating, and then adjust the settings as required before creating the drawing. Properties can be defined separately for each drawing that you create, but it is advisable to save the most commonly used settings in property files for future use, for example, in The properties are stored in property files. Automatic drawing settings are defined before drawings are created.Īutomatic drawing settings are settings that are defined through:ĭrawing, view and object properties in various drawing types.

The dimension line of a datum feature and the datum are indicated apart from each other. Annotating an Axis or Center PlaneĪ datum feature is indicated by combining the dimension line and datum. To express the design intention with strict accuracy, pay attention to the position where you indicate the datum. The position of the datum symbol on the drawing is also relevant to the target area. The letters indicating the datums are always oriented to the direction the reader looks at the drawing. Datum symbols use either a white or black triangle. Drawing Indications of Datum Featuresĭatums are indicated using the following symbols (datum symbols). ![]() ![]() Therefore, a surface plate, gauge, or mandrel, which has a more precise surface, must come into contact as a simulated datum.Į Surface plate, gauge, mandrel, etc. The surface of a part indicated as a datum is not an exact shape. Datum System A group of datums created by combining more than one individual datum in order to use it as a reference for toleranced features. Simulated Datum Feature An actual surface with sufficiently precise shape that comes into contact with a datum feature and is used for establishing a datum (e.g. Datum Feature A real (non-ideal) integral feature of a target used for establishing a datum (e.g. ![]() Multiple datums can also be combined to make a datum system that specifies a feature. A datum is a plane, a straight line, or a point that is used as a reference when processing a material or measuring the dimensions of a target.Ī datum is defined as follows in the ISO standard: ISO 5459:2011 “One or more situation features of one or more features associated with one or more real integral features selected to define the location or orientation, or both, of a tolerance zone or an ideal feature representing for instance a virtual condition.” Types of Datumsĭatums are established using datum features and simulated datum features. ![]()
