cylindercal borehole

Question

Hi everyone, 
 In plaxis 3D, the borehole is cuboid , can I create cylindrical borehole instead of cuboid ? 
 Thanks in advance

Hi Maha, 
 A screenshot would help me understand what you mean. 
 The Borehole tool creates boreholes that are locations in the drawing area where the information on the position of soil layers and the water table is given. Each defined soil layer in the borehole tool is used throughout the model contour, extending to the geometry's boundaries. 
 Now, when creating a new geometry, you create an orthogonal parallelepiped (Ymin, Ymax, Xmin, Xmax). However, if you wish to have a different geometry (e.g. a cylinder), you can do so directly in Structures mode without creating a borehole first. The steps to do that are the following: 
 
 You create a circular polycurve 
 You select the polycurve, right-click and create a surface 
 You extrude the surface at the desired depth intervals 
 
 If your geometry is curved, you must apply the correct prescribed displacements on the sides of the geometry to account for the boundary fixities you would typically have.
