The app functions include:

1. Turn on snap point: This app lets you snap support, and pipe inline assets like fittings, valves, etc. which by default are turned off by Autodesk® AutoCAD® Plant 3D.

This can be useful in the case of measuring, and placing new components in the correct position. No need to explode the entity to get the snap points like the normal process. The quadrant points for the circle cares about the rotation of the circle rotation so if you have a cylinder rotate 45 degrees (or any degree) the start point also starts at that angle this may be beneficial but also can make some confuse. 

2. Draw bounding box: draw a bounding box around any kind of object not only letting you get the visual of the object limit but also giving information about volume, length, min point, max point, etc. which can be useful in several cases:

• Get notes directly on the drawing.
• The bounding box also can be stretched after created.
• The volume and dimension can give useful information during layout drawing, transportation in containers, etc. 

3. Link spec: Allow user to link the spec to the current project without having to copy it to the project, so you can have a centralized place for specs and same spec for all project

Note: This app uses a custom installer (and not the standard App Store installer).
