2-D Dimensioning + Text

With the following functions you apply dimensionings parallel to a line. You can use the following identification types to select this line:

• Parallel to 2 dimensioning points: Use 2 points to identify the line to dimension. The points are also simultaneously the termination of the line and where the projection lines begin. The projection lines form a right angle to an imaginary line through these 2 points. The dimension line is parallel to the points. Specify a 3rd point for the position of the dimension figure.
• Parallel to line: Identify the line to dimension. The projection lines form a right angle to the line. The dimension line is parallel to the line. Specify a first point for the position of the dimension figure.
• With reference line: Dimension parallel to a reference line. The two points that you identify after the reference line specify the length of the line segment to dimension. Then select a point for the position of the dimension figure.
• 2 reference points: Use two points to select a reference line for the position of the dimension line. The next two points specify the length of the line segment to dimension. Starting from them, the projection lines are drawn at a right angle to the reference line, which you identified by means of the first two points. Then select a point for the dimension line.
• Variable: The identified element determines the type of dimensioning.
  The identification of
• points creates a linear dimension
• lines creates an angular dimension
• circles or arcs creates a circle dimension.
  
• 2 points direct: Identify 2 points between which the dimensions are then placed without projection lines.

In addition, you have the following dimensioning types available.

 

Function		Description	Example
	Linear dimensions	The linear dimensions are defined by means of 3 points. The first two points specify the start and end points of a line to be dimensioned. The third point specifies the position of the dimension line and the dimension figure.
	Chain dimensions	The chain dimensions are defined by means of two points for the projection lines and one point for the dimension figure. The succeeding points can then be identified for further dimensions.
	Parallel dimensions	The parallel dimensions use the point options to define the first steps by means of the start and end points of a line. The third point specifies the position of the dimension figure and the succeeding points specify the further steps.
	Running dimensions	Running dimensions are chain dimensions with the same reference point. The dimension figures refer to this point.
	Half-section dimensions, parallel dim. points	This function generates the dimensioning of symmetrical parts as individual dimensions in half-section, i.e. with a hidden projection line and shortened dimension line. You can find this function at 2-D Dimensioning + Text > Direct. The dimensions are defined by identifying the symmetry line, the dimension end and the position of the dimension figure.

	Half-section dimensions (diameter)	This function generates the diameter dimensioning of symmetrical parts as individual dimensions in half-section, i.e. with a hidden projection line and shortened dimension line. You can find this function at 2-D Dimensioning + Text > Direct. The diameter dimensions are defined by identifying the symmetry line, the dimension end and the position of the dimension figure.
