Shallow Structures
In general, most reference structures in MH Pro! are not set up to stack structures that are too
shallow to fit within the smallest available base.
When MH Pro! encounters this situation, it will pop up this warning message:
The structure is too shallow to be built with this structure design.
In this situation, some precasters will increase the secondary pour or sump in the structure so
that more of the structure will be below the invert, deeper in the ground. Here is how to make
MH Pro! do this when you need it.
Steps for shallow structure builds
1. On the Structure Design screen, increase the Build Tolerance High to the maximum
additional depth that you will allow the structure to be placed deeper in the ground.
2. Set the Too Tall Behavior to one of:
1. Adjust Leave Short. This will remove any Leave Short that is specified before
driving the structure deeper into the ground.
2. Lock Leave Short. This will maintain any specified Leave Short and drive the
structure deeper into the ground immediately.
Apply these changes, then click Find Stackings again on the Automatic Stacking screen.
Stacks should now be generated that will work for this structure.
