Structural Member

Mac OS, English

Insert a standard structural member from a library by selecting sketch lines, curves or model edges.

General Usage Instructions

The app will appear in the CREATE panel of the MODEL workspace.

How to use

Structural member command:

  1. Create a skeleton sketch or create a skeleton model, in which lines, curves or model edges will be used as reference geometry for inserting structural members.
  2. Start the command.
  3. Select structural members.

           1. Select the sketch line or curve

           2. Name the structural member (example: AAAA0001 minimum 4 letters and 4 numbers)

           3. Select a standard

           4. Select family

           5. Select size

           6. Select thickness/weight

           7. The orientation of the member

           8. Select desired rotation in degrees

           9. Select desired offset by X-axis in mm (the user can override by writing “in” after the desired offset value)

         10. Select desired offset by Y-axis in mm (the user can override by writing “in” after the desired offset value)

4. If the selection is valid the user will see a visualization of the result. If the user presses the OK button the new structural member will be added as a new body in a new component. The name of the body will be the given name followed by the standard, the family, the size, and the length of the member (example: AAAA0001 GB_EN PFC 100.0x50.0 L=2500.0). The component name will be the same, but will not update if a length update feature is used.

5. If the user starts the command again the default selection for standard, family, size, and thickness/weight will be the same as the previously inserted member. The name will also be the same plus the number incremented by one (example: AAAA0001 the second member will be given the name AAAA0002).

The length update function is used to update the length in the members’ names after a change has been done.

The user can switch between the Metric and Imperial systems of measurement for the length displayed in the body’s name.

Note: Copied and patterned components are counted in the list however Mirrored components are not counted.


Add custom shape command

  1. Select sketch entities that form the shape.
  2. Add shape sizes and thickness.
  3. Save the shape.

All saved shapes can be found in the custom shape library and can be used the same way you insert other standard shapes.

How to edit standard libraries

Inside app folder usually C:\Users\Username\AppData\Roaming\Autodesk\ApplicationPlugins\Structuralmember.bundle\Contents

Enter the resources folder and you will find all standards as excel files.

Select the desired standard and open the excel file.

You will see the data for the shape and a simple sketch for each shape with its dimensions, follow the established pattern and you can add and remove additional shape sizes and thicknesses.

How to add standard libraries

Copy one of the standard excel files and rename it to the standard that you are going to add.

There is an additional folder for each standard containing the flag icon picture.

Copy one of the standards folders and change its name to the standard you chose.

If you want to see a different icon for your new standard you should place a 16x16 pixel png file inside that folder replacing the existing one.

Use the established pattern to populate your data for your new standard following the simple sketch dimensions.
