Feature Summary

Info

Set the 2.5D Dimension in the Information Mode. If this dimension is set, if the section update occurs, the 2.5D dimension is also updated according to the section.

With the 2.5D Dimension, the user can input dimensions on the 3D projected section created from CIM.

Linear 2.5D Dimension [Shortcut command: LD2]: Draws a linear 2.5D dimension line in Iso View.

Aligned 2.5D Dimension [Shortcut command: AD2]: Draw an aligned 2.5D dimension line in Iso View.

Feature Explanation

Generate Drawing > 2.5D Dimension > Linear / Aligned 2.5D Dimension

Configuration of Iso View

On how to create an Iso View, refer to CIM's Drawing View generation method. [Named View]

  • Drafter's Iso View displays the 3D coordinate system on the angle viewed to create the View in the lower left corner. This GUI can be used as a reference when measuring the axial Delta value of the current member.

  • In Generate Drawing > Style > Concrete Member Style, select Hide Invisible Lines in 3D to make the invisible edge lines not appear in the Iso View

How to Create Linear 2.5D Dimensions in a 3D View Section Using CIM

This manual outlines the process for creating linear 2.5D dimensions in a 3D view section within CIM.
Linear 2.5D dimensions are a unique function of CAD ID that combines traditional linear dimensioning in orthogonal directions (based on the CAD workspace X and Y planes) with the tilt direction of a structure.

  • [Remember #1]

    • At the bottom left of the 3D view section, the 3-axis coordinate system is displayed at the viewed angle for creating the 3D section.
      This GUI is used to measure with reference to the axial Delta direction of the current member.

    • The position of the 3-axis coordinate system can be adjusted by dragging it on the work screen.

  • [Remember #2]
    Application Criteria for Linear 2.5D Dimensions and Aligned 2.5D Dimensions

    • Creates separate linear and aligned dimensions based on where the dimensions are placed based on the 3-axis coordinate system of the 3D view section.

    • Dimensions in the Delta-Z direction, which are the X and Y planes in the CAD work screen, are created as linear 2.5D dimension.
      The direction of dimensions to be created in the structure is based on the 3-axis coordinate system, and the dimensions in the Delta-X and Y directions are created as aligned 2.5D dimension.

  • [How to Run]
    Run the Linear 2.5D Dimension function from the tree menu or use the command LINEAR2.5DDIMENSION (LD2) in the Command window.

    • Specify the distance criteria for display [Distance(D)/Delta-X(X)/Delta-Y(Y)/Delta-Z(Z)/ <D> : Z
      Specify first extension line origin :
      Specify second extension line origin :
      (lightbulb) Create a dimension to represent the height in the Z direction with a linear 2.5D dimension.
      When you enter the Z value, the text for specifying the first dimension auxiliary point appears and specifies the location point for creating the first dimension.
      Next, specify the next point to represent the dimension.

Linear Dimension is used to express the value of the dimension line horizontally or vertically.

Use Aligned Dimension when the value of the dimension line is not horizontal or vertical.

  • [Command]

    • Specify dimension line location :
      (lightbulb) Specifies where the dimension will be created.
      The mouse can be pointed in the direction to indicate the dimension,
      or the length value can be entered directly in the Command window.

  • [Command]

    • Input slope angle (Press Enter key to skip) :
      Specify second point :
      (lightbulb) This process adjusts the location of dimension creation to match the slope of the structure.
      (Press Enter if no slope condition is needed.)
      Set the tilt based on the Snap Point of the object.

      (lightbulb) If dimensions need to be created continuously, specify the location of the next dimension,
      or press the Esc button when dimension creation is complete.

① Change the style to make the location of dimension creation clearly visible.

② Run the linear 2.5D dimension function.

③ Set the distance value standard for display.

④ Specify the first dimension auxiliary point.

⑤ Specify the second dimension auxiliary point.

⑥ Enter the tilt angle.
