File Management

  •   Takes advantage of the Mac OS X document-based app environment. Easily save, create, duplicate, move, and rename files.
  •   The MacSlope file format (.msl) is easily shared and is fully compatible with our companion app MobiSlope, designed for the iPad.
  •   Import drawing geometries from CAD .dxf files.


  •   Unlimited number of regions in a drawing.
  •   Work in Metric (SI) or Imperial (British) units of force, stress, and distance.
  •   Analyze slope geometries left-to-right or right-to-left, as desired.
  •   Draw accurate slope geometries quickly with a simple, intuitive user interface that includes snap-to-grid and line-trimming.
  •   Edit geometry distance-elevation coordinates in tabular form. Import coordinates from .csv files or clipboard selection.


  •   Unlimited number of materials in a drawing.
  •   Save materials to the Material Library for easy re-use.
  •   Use of Mohr-Coulomb strength model to define soil strength.
  •   Define a soil whose strength changes with depth.
  •   Define material anisotropy over specified ranges or using the transverse isotropic model.
  •   Model fluid and hard layer regions using the no strength and impenetrable strength models.


  •   Unlimited number of reinforcements in a drawing.
  •   Save reinforcements to the Reinforcement Library for easy re-use.
  •   Model reinforcements as anchors, geosynthetics, or piles.
  •   Use advanced strength parameters to customize reinforcement force distribution, inclination, magnitude, and dependence on the computed FOS.


  •   Create multiple stages within the same drawing file to efficiently analyze different geometry, material, and analysis sensitivities.
  •   Unlimited number of stages in a drawing.


  •   Assign unique pore pressure conditions for each material.
  •   Use easily defined piezometric surfaces.
  •   Use ru or B-bar coefficients.

Search Types

  •   Tension cracks.
  •   Partially and fully submerged slopes, either by including fluid regions in the slice calculations or by applying external hydrostatic forces.
  •   Vertical and inclined point and surcharge loading.
  •   Seismic loading, input as a horizontal acceleration for pseudo-static analysis.
  •   Material and reinforcement parameters as random variables for use in probabilistic and sensitivity analysis.


  •   View contour and heat map displays of the calculated factors of safety.
  •   Use the slice inspector to view slice details and forces graphically.
  •   Create custom plots of FOS convergence, force and stress over the slip segment, and moment-force FOS with respect to inclination of interslice forces.
  •   View summaries of any warnings and/or filtered trials so you can interpret the results with confidence.


  •   Create custom reports as PDF or HTML, using staged results and custom plot content. See a sample report here.
  •   Annotate the drawing using customizable labels and automatic slope angle recognition.
