[讨论]：在objectARX 中有没有与VBA相对应的函数?

在objectARX 中有没有与VBA相对应的函数?
例如: VBA中
Set pl = ThisDrawing.ModelSpace.AddLightWeightPolyline(pt)
在objectARX 中有没有与之相对应的函数?

VBA启动ACAD的自动化模型，找到模型空间，在pt位置创建AcDbPolyline，然后将它加入到模型空间中。

任何二次开发工具，最终都是通过ARX来实现的，ARX是最底层接口，所以只能有VBA没有的，不会有ARX没有的。

你可以查看联机帮助，索引里面输入setLineWeight就可以看到了。凡是派生自AcDbEntity 的子类，都可以用。

[field]
AcDbEntity::setLineWeight Function virtual Acad::ErrorStatus

setLineWeight(

AcDb::LineWeight newVal,

Adesk::Boolean doSubents = true);

newVal Input AcDb::LineWeight for the entity
doSubents Input to apply the lineweight change to subentities

This method sets the entity to use lineweight. If the entity owns subentities
and doSubents == Adesk::kTrue, then the line weight change will be
applied to the subentities as well.

Returns Acad::eOk if successful.

Function implementation in derived classes

If this function is overridden and wishes to set the line weight of the entity,

then it must call AcDbEntity::setLineWeight() passing on the lineweight
and doSubents arguments.

It is also possible for this function's implementation to deal directly with any
subentities and pass a doSubents value of Adesk::kFalse to AcDbEntity:: setLineWeight().

If the line weight setting operation is successful, then this function should

return Acad::eOk. If lineweight is not an acceptable value, then this
function should return Acad::eInvalidInput. Any other error return values
are up to the implementor.
