Rotate Mode
Shapes ExtrusionsRotate
In this mode, you may interactively rotate either a profile or a face
to get a three-dimensional solid.
To rotate a face, you may pick one or more faces of an existing solid
(if more than one face are picked, the last one will be rotated) and enter
the Rotate Mode afterwards.
If you want to rotate a profile, you must define a set of points that
form a closed polygon line. The points are always located on the current
active .
In both cases, an axis must be defined that will be used as center
of rotation. The axis must be on the same plane as the one where the profile
or face is located.
The axis will be plotted as a blue arrow.
Creation steps to rotate a profile
Defining the axis:
You
may either pick an edge or define a new edge. If
you have picked an edge and you enter the Rotate Mode, it will ask you
to allow it to align the WCS to this edge to have the axis on the same
plane as the later to be defined polygon. If
no axis is defined, a default axis will be used later.
Creating the solid:
When you first enter this mode, you will be asked
to double-click on the working plane to mark the first point of the polygon
line. The cursor鈥檚 location will be projected onto the currently active
.
After you have defined the first point a rubber-band
appears from this point on up to the mouse pointer. This band represents
the first line of the profile polygon. Repeat this procedure for as many points as necessary.
To finish the polygon, choose the last point to be on the same location
as the first one (always remember to release the mouse button after double-clicking,
before dragging to the next point). When you have defined the profile, the Rotate
Profile dialog box appears, showing you all values of the new solid.
If they are correct, press the OK button to create the new solid.
Creation steps to rotate a face
Defining the axis:
You may either pick an edge or define a new
edge. If you have picked an edge and you enter
the Rotate Mode, it will project the edge on that plane that is defined
by the picked face. If no axis is defined you will be asked to
define one.
SHIFT key
By pressing the SHIFT key after the first point
has been set, the cursor movement is fixed in one coordinate and may only
be moved in the other and vice versa.
Creating the solid:
Display of locations
Throughout this mode the current mouse location
will be displayed in the lower right corner of the .
Snap mode
All positions will be adjusted to the snap
grid when active.
Cancel interactive mode
You may cancel this interactive mode at any
time by pressing the ESC key. Pressing ESC again in the following dialog
box will terminate the sphere creation.
Undo last double-click
You may go back to the last step by pressing
the BACKSPACE key. Pressing this key in the interactive mode will undo
the last double-click.
Numerical specification of coordinates (TAB key
and SHIFT+TAB key)
To precisely specify the shape coordinates,
you may press the TAB key whenever a point must be double-clicked. A small
coordinate dialog
box will open in which you may specify the shape coordinates numerically.
The dialog entries take over the coordinates
at the cursor position on the .
However, if the SHIFT+TAB key is pressed, the coordinates are always set
to zero.
Pick tools to specify coordinates
You may snap the location to a previously defined
shape鈥檚 corner, cylinder radius, etc., by activating a point
pick tool, at the moment when the next point must be specified. The
double-click will be processed by the pick functionality to specify the
location of a point. The picked point will then be taken as the selected
location.
