"This script creates a spiral nurbs surface with optional construction history. You can\n" +
"create spirals along a fixed axis (xyz) or nurbs curves.\n" +
"\n" +
"To operate the tool on nurbs curves, select one or more curves before executing the script.\n" +
"\n" +
"Construction history will give you access to the spiral parameters after its creation.\n" +
"New attributes are added to the spiral surface node, that let you modify the geometry\n" +
"afterwards. In addition you can go into the 'spiralConstruction' group, created for each\n" +
"spiral surface, to alter the construction objects directly.\n" +
"\n" +
"If you start changing the shape of a construction nurbs curve, you may notice unwanted\n" +
"changes in the spiral geometry. In this case remove the construction history and use a wire,\n" +
"wrap or any other of Maya´s deformers to modify/animate the spiral further.\n" +
"\n" +
"Profile Radius\n" +
" Set the profile (nurbs circle) radius.\n" +
"\n" +
"Keep Profile Tangent\n" +
" Enable this option to keep the profile tangent to the spiral curve, if the spiral\n" +
" length and/or turns values are changed. This will avoid unwanted shearing.\n" +
"\n" +
"Spiral Start Radius\n" +
" Set the spiral start radius.\n" +
"\n" +
"Spiral End Radius\n" +
" Set the spiral end radius. This option is not available for user defined curves.\n" +
"\n" +
"Length\n" +
" Set the spiral length. This option is not available in the user interface for user\n" +
" defined curves, but you can access this attribute later on, if construction history is\n" +
" enabled. For fixed axes the value is measured in your current world space units, user\n" +
" defined curves have a relative value range from 0 to 1.\n" +
"\n" +
"Automatic Span Adjustment\n" +
" Calculate the number of spans for the spiral surface depending on the spiral turns value.\n" +
" The currently used formula to always guarantee a smooth surface is 'Turns * 8'. You may\n" +
" want to disable this feature, if the number of turns is going to be animated, because\n" +
" there can occur visual changes in the geometry, when an isoparm is inserted or removed.\n" +
"Spiral Spans\n" +
" Set the number of spans for the spiral surface.\n" +
"\n" +
"Axis\n" +
" Create the nurbs spiral along a fixed axis (xyz) or user defined nurbs curves.\n" +
"\n" +
"Rebuild Curve\n" +
" Enable this option to rebuild the construction nurbs curve uniformly.\n" +
"\n" +
"Curve Spans\n" +
" Set the number of spans used to rebuild the construction nurbs curve.\n" +
"\n" +
"Keep Construstion History\n" +
" Enable construction history to alter the spiral parameter afterwards.";
