Tech Tip: Hole Groups and Hole Reference Points

Hole groups tech tipUsing good modeling techniques can enhance the output for drawings produced by SDS/2, minimizing the time required to clean up drawings. Good modeling techniques range from creating hole groups using Hole Pattern Options or repeating holes, to specifying the desired material dimension reference point, and many things in between.

Here are several examples of how creating the same hole group in different ways produces different results on the drawings.

The first example shows creating a hole group by left-clicking to locate each hole in the model. Additional dimensions are added and extra time would be required to clean up the drawing.

The second example shows creating a hole group by locating the first hole and then middle-clicking to repeat the rest of the holes in the model. This produces good results that require minimal to no time spent cleaning up.

The third example shows creating a hole group by using the Hole Pattern Options available inside the Hole Add window. Results are identical to the second example.

The fourth example shows creating a hole group with an offset reference point by using the Hole Pattern Options available inside the Hole Add window. Keep in mind the 3-inch dimensions to the hole reference points can be turned off in Job or Fabricator Options > Dimensioning Criteria. This requires little to no cleanup time.

The fifth and final example shows creating a hole group with a reference point that is rotated incorrectly. This produces undesirable results that most users would delete and add almost all dimensions from scratch.


Creating Custom Buttons for Parametrics, Reports, and Advanced Selection

Creating custom buttons to your toolbar that run Parametrics, Reports, and Advanced Selections is done easily in SDS/2 version 7.3.

To create a custom button, first access your Toolbar Configuration in Modeling by going to the Options pull-down menu and selecting Toolbar Configuration. 

Next, you will need to create a Custom Launcher by clicking Launcher Manager, open the tab corresponding to which type of launcher is to be created (Parametrics, Reports, Advanced Selections), and select Add.

In the Launcher Edit window, specify the Button text which will make up a text button, specify the Hover text which will pop up when your mouse is hovered over the button, specify the Script which is the Parametric, Report, or Advanced Selection file that is to be run when the button is clicked. Small icon and Large icon are optional fields used to specify picture buttons that can be placed on the toolbar instead of a text button. Once OK is clicked, the Hover text specified will be shown in the list of available launchers.

To add a custom button to your toolbar, close the Launcher Manager, choose Parametric Launchers, Report Launchers, or Selection Launchers from the Command Group: drop-down menu, and drag the button to the desired location on your toolbar.


AISC Single Angle Thickness Requirements

When designing single-angle connections, SDS/2 will follow the recommended minimum angle thicknesses found on page 10-133 of the AISC 14th Edition Manual. Recommended minimum angle thicknesses are 3/8 in. for 3/4 in. and 7/8 in. diameter bolts and 1/2 in. for 1 in. diameter bolts.

Users specify the angle size for SDS/2 to use when designing single-angle connections in Job or Fabricator Options > Standard Fabricator Connections > Clip Angle Configurations > Single, Bolted if bolted, or Single, Welded if welded.

Single Bolted

If the angle thickness specified is less than the AISC recommended minimum, a failed message of Angle thickness less than minimum required by AISC will be seen in the beam edit window when a single-angle connection is specified.

Failed Message

To override this AISC requirement, turn on the Design non-AISC single angle connections check box found in Job or Fabricator Options > Design Criteria.
