Object 32 "Dimension Perimeter" (Entity Type "Object") Changed in Version 2021.0

Data Block Sequence

Data Block 000( Position )

Data Block 000( Direction )

Data Block 100( Perimeter )

Data Block 110( Prefix )

Data Block 110( Value )

Data Block 110( Postfix )

Data Block 110( Tolerance1 )

Data Block 110( Tolerance2 )

Data Block 230( Options )

Parameters

Position

[MKI_POINT] Position of the dimension.

Direction

[MKI_POINT] Direction of the dimension.

Perimeter

[double] The perimeter value is explicitly stored in Perimeter, using internal [mm]. When updating this dimension, the value stored in Perimeter is written to Value, considering the current scale and length unit. The value of Perimeter itself remains unchanged!

Prefix

[MKI_STRSHORTW] Prefix text for the dimension.

Value

[MKI_STRSHORTW] Dimension text for the dimension.

Postfix

[MKI_STRSHORTW] Postfix text for the dimension.

Tolerance1

[MKI_STRSHORTW] Upper tolerance text for the dimension.

Tolerance2

[MKI_STRSHORTW] Lower tolerance text for the dimension.

Options

[MKI_DIMLARGE] Dimension parameters.

Prefix, Value, and Postfix will be connected to one text ("Main dimension text") without separating characters.

Attributes New in Version 2021.0

A perimeter dimension may contain attribute data blocks (see MKI_BLOCK_ATTRIBUTE) only of type "local". They must be placed behind all other datablocks. Attributes of types "outline" and "point" must not exist. The total number of local attributes per object is limited to MKI_ATTRIBS_PER_OBJECT.

Specific Usage of Data Block 230

|System|

0;

This perimeter dimension will be lettered with the font "DINDRAFT", using pen 1. The main dimension has a text size of 5 mm, the tolerances have a text size of 3.5 mm. The dimension number is rotated and will not automatically be updated.

The dimension will be calculated according to the settings in the coordinate system 0 ("- Standard -").

The image above shows a perimeter dimension created using the settings described above. The points Position and Direction place and rotate the dimension number.
