Convert Surface Dialog 1227
Number of Points—
Specifies the number of points
in the new curve.
Prev iew—When on, previews the effect of t he
conversion in viewports. Default=on.

This dialog provides a general way to convert one
kind of a surface to another or to adjust a surface’s
parameters.

Loft tab
If the surface isn’t already a loft, this tab converts it
to the kind of loft you indicate.

Loft dialog (page 1–1234).
From U Iso Li nes—Usescurvesalongthesurface’sU
dimension to construct a U loft.
Fr o m V Is o Li n e s —Uses curves along the surface’s
V dimension to construct a U loft. If the surface
was already a U loft, set this to change the lofting
dimension.
From U and V Iso Lines—Uses cu rves f rom b oth the
U and V dimensions to construct a UV loft.
UCurves—Sets the number of curves in U.
VCurves—Sets the number of curves in V.
Use Poi nt Curv es—When on, constructs the loft
from point curves instead of the default CV curves.
Default=off.
Ext r a Poi nt s per S e gment —This control is available
only for UV lofts (From U and V Iso Lines). Lets
you increase the number of points in each segment.
Fuse P oi n ts—This control is available only for
UV lofts (From U and V Iso Lines). When on,
fusespointsatcurveintersectionstoensurethat
the U and V curves continue to intersect when
you edit the surface, and that the surface remains
coincident with its parent curves. UV lofts
constructed from intersecting curves b ehave more
predictably. Default=on.
Fit Point tab
If the surface isn’t already a point surface, this tab
converts it to a point surface.
In U—Sets the number of point rows (in the
surface’s U axis).
In V —Sets the number of point columns (in the
surface’s V axis).
Tolerance—When chosen, the software calculates
the number of points. This option rebuilds the
surface according to accuracy. The lower the
Tolerancevalue,themoreaccuratetherebuild.
Increasing Tolerance enables the surface to be
rebuilt using fewer points.
CV Surface tab
If the surface isn’t already a CV su rface, this tab
converts it to a CV surface.
This tab is the default.
