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.
