Cone Creation Mode
Shapes Cone
In this mode, you may interactively define a cone by double-clicking
its base center point, its top and bottom radii and its height in the
currently active .
The axis of the cone will always be oriented perpendicular to the currently
active .
To define a cone with a different axis, you must first change the working
plane’s orientation by using local coordinate systems.
Creation steps
When you first enter the mode, you will be
asked to double-click to mark the base centerpoint of the cone. The cursor’s
location will be projected onto the currently active to define the center (always
remember to release the mouse button after double clicking, before dragging
to the next point).
After the first point has been set, you may
specify the bottom radius of the cone by again double-clicking at a location
on the working plane. During this operation, a rubber-band circle will
be displayed indicating the current size and location of the cone’s
bottom circle.
The next step allows you to specify the height
of the cone by double-clicking a distance perpendicular to the working
plane. During this operation, a rubber-band cone will be displayed indicating
the size and location of the currently defined cone.
In the last step, you may specify the top
radius of the cone by double-clicking a distance from the center of the
top circle. To obtain a full cone, you may specify a zero radius. During
this operation, a rubber-band cone will be displayed indicating the current
size and location of the cone.
Finally, a Cone
dialog box appears where you may verify your settings and assign a
,
a
and a material
for the new cone.
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 cone 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’s 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.
