Check out the new Quick Constraints function in Surpac 2019 which makes constraints easier and faster while being able to inspect the data on graphics.
In this article we focus on how to constrain a block model below a topographic surface (Note that SDM surface cannot currently be accessed using the normal graphical constraint form and this method is the only way to do SDM surface constraint at the moment).
The Quick Constraint function requires that your block model and the constraint you want to use are both displayed on graphics.
The simple process is shown below:
1. Open and display the Block Model and DTM/SDM surface on graphics as normal
