  1. AEC Dimensions and Elevations in ADT Unit 7

  2. AEC Dimensions • AEC Dimensions are automatic dimensions based on Styles. • There are many variables in the dimension system, so there are many dialog boxes.

  3. AEC Dimensions • AEC Dimensions can be accessed through the Document pull-down menu aecdimadd

  4. AEC Dimensions • Standard AutoCAD dimensions can be converted into AEC Dimensions, and AEC Dimensions can be mixed with the manual AEC and standard AutoCAD dimensioning systems.

  5. AEC Dimensions • The Chains tab allows users to specify the number of chains

  6. AEC Dimensions • The Display Properties tab allows users to change the properties of the display components of an AEC dimension style

  7. AEC Dimensions • The Contents tab in the Display Properties dialog box lets you specify the objects and points to be dimensioned on an AEC dimension style

  8. AEC Dimensions • AEC Dimensions can dimension only AEC objects such as walls, windows, stairs, structural members, and so on.

  9. AEC Dimensions • If you add non-AEC objects to AEC objects, you have to add manual dimension points to the automatic AEC dimension. Else you have to create manual AEC or standard AutoCAD dimensions.

  10. AEC Dimension Wizard • Use the Wizard to change a number of AEC dimension style properties.

  11. AEC Dimension Wizard • Arrowhead shape and size • Length and color of extension lines

  12. AEC Dimension Wizard • Distance between dimension chains • Dimension text style, size, and color • Rounding-off value

  13. AEC Dimension Wizard • Layer assignment • Color of dimension lines

  14. AEC Dimension Wizard • If you choose a dimension style that has its property source set to System Default, you get a warning message. • If you want to edit the style, close the Wizard, open the style in the Style Manager, and set the display property source to a style override.

  15. AEC Dimension Styles • If the AEC dimension style you choose to edit is based on the same AutoCAD dimension style for different display representations, the edits you make apply to all display representations. • To avoid this, make sure that the AEC dimension style uses different AutoCAD dimension styles for different display representations.

  16. Elevations • Elevations can be created through the Document pull-down menu

  17. Elevations • You draw an elevation line by specifying a start point and an endpoint for the line in relation to your building model.

  18. Elevations • Depending on the direction in which you drew the elevation line, the elevation mark points in the direction of the elevation view.
