Build surface

X-PAD Office Fusion is able to calculate, according to the set parameters, a three-dimensional surface composed by a triangular model starting with points of survey or Point clouds.

You can calculate the surface based on the parameters set using the function Build surface.

• Click Surface.

• Click Build surface.

  

• This commands opens a new panel, where we can enter the parameters.

  

• The Build surface page shows the main options to create the surface:

  • Surface: sets the Surface subproject to save processing.

  • Add: activates a selection window from which you can choose a survey subproject or Point clouds to perform the creation of the triangular model.

    

  • Remove: allows to remove from the survey list and point clouds an element.

• If you have selected at least one Point clouds, then you must perform the following settings:

  • Generation mode: sets the option Use all points or Grid to build the surface.

  • Grid step (meter): sets the step of the grid for sampling of Point clouds. The option is activated if the generation mode was selected Grid.

  • Decimation factor: sets a reduction factor in the number of points in the Point cloud. The option is activated if the generation mode was selected Use all points.

• Build options are used to customize and surface creation:

  • Use breaklines: enables/disables the use of breaklines to build the model.

  • Use boundary lines: enables/disables the use of boundary lines to build the model.

  • Check triangles side length: enables/disables the length control of triangle sides. If this option is active, no triangles with sides larger than the set maximum length will be created.

• The Advanced options page shows additional options for the surface creation:

  

  • Split breaklines: if there are long breaklines, triangles are created that lie on that breakline generating triangles with long sides. This option enables/disables to split the breaklines in parts, defined by the field Split distance, to create better shaped triangles.

  • Ignore points with elevation zero: toggles the use of points with a zero-height value in the model.

  • Remove peaks: toggles control of the peaks of triangles based on the value set in the option Peak angle (°). If the control is active, triangles that overtake the value of the control will not be created.

  • Smooth surface: Enables/disables the calculation of rounded surfaces.

• Color options allow to customize the surface rendering:

  • Style: sets options for the coloring of triangles, the options available are:

    • Fixed color: use the color associated with triangle entities.

    • By elevation: use the color scale set as a function of elevation.

    • Color of the point: use the color of point clouds points.

  • Color: sets the fixed color to be associated with triangles.

• Click Build to perform the surface calculation.
