Editable Patch (Vertex) 963
vertex at the top of a spherical patch object, the top
four patches are also deleted, leaving a hemisphere.
Break—Breaks a vertex into multiple vertices.
Use this if you need to split open an edge to add
another patch or for general modeling operations.
Select a ver tex and then click Break. After the
break select t he individual vertices and move them
to separate the edges.
Hide—Hides selected vertices and the attached
patches.
Unhide A ll—Restores any hidden sub-objects to
visibility.
Weld group
Selected—Welds selected vertices that fall within
the tolerance specified in the Weld Threshold
spinner (to the right of the Weld button). Select
the vert ices you want to weld between t wo different
patches, set the spinner to a sufficient distance,
and click Selected.
Target—Turn on and drag from one ver tex to
another to weld the vertices together. The dragged
vertex fuses to the target vertex.
The pi xel s spinner to the right of the Target
button sets the m aximum distance in screen pixels
between the mouse cursor and the target vertex.
Tangent group
These controls let you copy orientation, and
optionally length, between handles on the same
object, or on different objects applied with
instances of the same Edit Patch modifier. The tool
doesn’t support copying handles from one patch
object to another, or between spline and patch
objects.
Co py—Copies a patch handle’s transform settings
to a copy buffer.
When you click Copy, the software displays all
handles on the selected object. When the mouse
cursor is over a handle end, the cursor image
changes to the one shown below. C l ick a handle
end to copy its direction and leng th to the p aste
buffer; this also exits Copy mode.
Pas t e—Pastes orientation information from the
copy buffer to a vertex handle. If Paste Length is
on, it also pastes the length of the copied handle.
When you click Paste, the software displays all
handles on the selected object . When the mouse
cursor is over a handle end, the cursor image
changes to the one shown below. C l ick a handle
end to paste the information from the buffer to the
handle. You can continue clicking other handle
ends to paste the information repeatedly. To exit
Paste mode, right-click in the viewpor t or click the
Paste button.
Pas t e Len gth —When on, and you use the Paste
function, the length of the originally copied handle
is pasted as well as its orientation. When off, only
the orientation is pasted.
Sur f ace group
Vi ew Steps —Controls the grid resolut ion of the
patch model surface as depicted in the viewports.
Render S teps—Controls the g rid resolution of the
patch model surface when rendered.
Show Interior Edges—Enables the display of the
patch object’s interior edges in wireframe views.
When off, only the object’s outline is v isible. Turn
on to simplify the display for faster feedback.
UseTruePatchNormals—Determines how t he
software smoothes the edges between patches.
Default=off.
