目前 Ellipse 仅几个还差很多

基本全了啊，还差什么？
命令: (xdrx_getpropertyvalue (entlast))

Class AcDbEllipse:

    ├─Center
    ├─EndAngle
    ├─MajorAxis
    ├─MinorAxis
    ├─Normal
    ├─RadiusRatio
    ├─StartAngle



命令: (xdrx_setpropertyvalue (entlast))

Class AcDbEllipse:

差好多呢

这个帖子的一些操作，本来想用 API ，没有找到，暂时用VLA

你那几个VLA的，上面都有啊。

(xdrx_getpropertyvalue ent "MajorAxis")
(xdrx_getpropertyvalue ent "MinorAxis")


(xdrx_setproepertyvalue ent "radiusratio"

这个图是ARX带的，API基本都有了。其他的如果VLA有都是根据这些能算出来的。

(xdrx_getpropertyvalue ent "MajorAxis")

Getpropertyvalue
选择对象:
Class AcDbEllipse:
    ├─Center
    ├─EndAngle
    ├─MajorAxis
    ├─MinorAxis
    ├─Normal
    ├─RadiusRatio
    ├─StartAngle

Setpropertyvalue

命令: (xdrx_setpropertyvalue (car (Entsel)))
选择对象:
Class AcDbEllipse:
  ├─Center(Point)
  ├─EndAngle(Real)
  ├─Normal(Point)
  ├─RadiusRatio(Real)
  ├─StartAngle(Real)

majorRadius	This is majorRadius, a member of class AcDbEllipse.
minorRadius	This is minorRadius, a member of class AcDbEllipse.
isNull	Returns Adesk::kTrue if this Ellipse has no gelib object within itself.
majorAxis	Returns the major axis vector (in WCS coordinates) of the ellipse. The major axis vector is the vector from the Ellipse's center point to its start point. The major axis vector's magnitude represents 1/2 the length of the major axis.
set	This function sets the properties of the ellipse to the values specified in the arguments. center, unitNormal, and majorAxis are in WCS coordinates. startAngle and endAngle are in radians, in the range -pi to pi. Positive angles are counter-clockwise when looking down the normal vector (that is, right-hand rule). A closed Ellipse will have a startAngle of 0 and an endAngle of 2pi. radiusRatio must be in the range 1E-6 to 1.0. The dot product of normal with itself and majorAxis with itself must be greater than 1E-12. majorAxis must perpendicular to normal within 1E-6. The difference between...
minorAxis	Returns the minor axis vector (in WCS coordinates) of the ellipse. The minor axis vector is perpendicular to the major axis vector. Its magnitude represents half the length of the minor axis.
setCenter	Sets center (in WCS coordinates) to be the center point of the ellipse. Returns Acad::eOk if successful, otherwise Acad::eGeneralModelingFailure is returned.
normal	Returns the unit normal vector (in WCS coordinates) of the ellipse. The normal vector specifies the plane that contains the ellipse.
setMajorRadius	This is setMajorRadius, a member of class AcDbEllipse.
paramAtAngle	Returns the first period parameter value at angle (in radians). The parameter value is in the range 0 to 2pi. The ellipse's majorAxis vector is the zero angle for angle. Positive angles are counter-clockwise when looking down the ellipse's normal vector (that is, right-hand rule).
setMinorRadius	This is setMinorRadius, a member of class AcDbEllipse.
radiusRatio	Returns the ratio of the ellipse's major radius to its minor radius. The returned value will be in the range 1e-6 to 1.0.
subGetClassID	Override this virtual function in a AcDbEntity-derived class to provide your custom implementation for
setEndAngle	Sets endAngle to be the end angle of the ellipse. Returns Acad::eOk if successful. If the Ellipse has no gelib object (that is, AcDbEllipse::isNull() returns Adesk::kTrue), then Acad::eDegenerateGeometry is returned.
setEndParam	Sets endParam to be the new end parameter of the ellipse. If endParam is less than the current start parameter, then it is incremented in steps of 2pi until it is larger than the current start parameter. Returns Acad::eOk if successful. If the Ellipse has no gelib object (that is, AcDbEllipse::isNull() returns Adesk::kTrue), then Acad::eDegenerateGeometry is returned.
setRadiusRatio	Sets ratio to be the new radius ratio for the ellipse. ratio must be a value between 1e-6 and 1.0. Returns Acad::eOk if successful. If the Ellipse has no gelib object (that is, AcDbEllipse::isNull() returns Adesk::kTrue), then Acad::eDegenerateGeometry is returned.
setStartAngle	Sets startAngle to be the new start angle for the ellipse. Returns Acad::eOk if successful. If the Ellipse has no gelib object (that is, AcDbEllipse::isNull() returns Adesk::kTrue), then Acad::eDegenerateGeometry is returned.
setStartParam	Sets startParam to be the new start parameter of the ellipse. If startParam is larger than the current end parameter, then it is decremented in steps of 2pi until it is less than the current end parameter. Returns Acad::eOk if successful, otherwise Acad::eGeneralModelingFailure is returned.

你这个是高版本CAD的吧，低版本没这么多，低版本这些也足够做了。
高版本那些设置半径啥的，都可以通过 setRadiusRatio 来实现

majorAxis 是 (mapcar '- cen startpt) 是长轴半径的一半
minorAxis 是短轴的一半

可以设置 RadiusRatio , 但这个只能改变其长宽比，要把 Ellipse 扩大或者缩小，需要修改 MajorAxis 及 MinorAxis , 这个两个修改了 Ellipse 就等同于原 Ellipse 的平行线了，API 只能改 RadiusRatio ，不能改 MajorAxis 和 MinorAxis

这个落了，等下版本提供，把高版本那几个也一起写到低版本下。

这样就可以写两个函数 Ellipse Spline Offset后保持原对象类型, 不会增加节点

spline情况复杂，简单可以，ellipse ok

很好奇xdrx_getpropertyvalue 和xdrx_setpropertyvalue 这两个函数arx代码是如何实现的？不会是逐个实体，逐个属性一一对应写出来的吧，要是这样得多大的代码量啊！老大太牛了！

先有单个实体, 如xdrx_text_ xdrx_line_ 等等，然后再有个框架整合，猜的
