Whendrawingafitspline,youcanspecifyadditionalsettingsforitsstartandendtangencies,tolerance
(howclosethesplinemustcometothefitpoint),andknotparameterization(controllingtheshapeof
thecurveasitpassesthroughthefitpoint).
TheonlyoptionforCV
splinesisDegree,whichcontrolshowmanybendsthesplinecantakeinagiven
span.

TheSPLINEDITcommandalsohasseveralnewoptions,includingimprovedEditVertexoptions.Youcan
noweasilyadd“kinks”orsharpcornerstoaspline.

YoucanusetheJOINcommandtoconnectlines,arcs,polylines,3D polylines,andhelixestosplines,as
longastheyareallcontiguous(inotherwords,theyshareacommonendpoint).Youmustselectthe
mostcomplexobjectfirst(inthiscase,thespline),andtheobjectstobejoined
donotneedtobe
coplanar.
