Cut Section

This part describes how cut section plane is created and viewed.

This part could be split into 3 actions,

  • Section Plane Definition
    • User can either select a primal plane or define custom plane by providing 3 points.
  • Clipping and visualization
    • User can click Show planes check box to visualize the plane.
    • User can invert clipping side about section plane.
    • User can visualize the intersection lines of model on the section plane.
    • User can visualize an offset section plane in addition to the prime section plane.
  • Section Plane translation and rotation.
    • User can translate and rotate the plane in parametric axes using slider controls
    • User can get the plane location by X, Y, Z axes intercepts with section plane.

Cut Section Option in the Context menu

Section Panel

XY Displays plane parallel to XY Plane
YZ Displays plane parallel to YZ Plane
XZ Displays plane parallel to XZ Plane
Custom Enables custom options like 3 Points.
3 Points Enables mouse mode to select 3 points to define and display plane.
Snap Vertex Allows user to select a vertex nearest to the mouse hit.
Show Planes Shows section planes.
Invert Toggles in clipping either side of  prime section of the plane
Slice Allows user to create a secondary section plane which cuts the model in other side.
Edges Displays intersection lines of model with the section plane.
Translate Slider Control Controls the translation of prime section plane.
About U parametric axes Rotates the prime and secondary planes about U parametric axis.
About V parametric axes Rotates the prime and secondary planes about V parametric axis.


Section Plane Location panel

  • Dynamically varying X, Y, Z  values refer to corresponding axis X, Y and Z intercepts with section plane respectively.
  • Translation step size controls the number of steps in the slider control. By default translation slider control has 100 steps. If user enter translation step size as 2, then 2 unit size step is considered as one unit step now. So the total number of steps in slider control is 50 (50 x 2 = 100). Simply, increase the step size for skipping steps and decrease the step size for more smoothing translation.
  • Rotational step size controls number of steps in the rotational slider control. By default rotational slider control has 180 steps, each step refers to 1 degree of angle. If user want to increment the angle of rotation as 2 degree per step, then enter 2  and apply. So the number of steps is now 90 (90x2=180).
  • User has to click Apply button to apply the changes made to step sizes.
