Topic: Sweeping a Solid

[huiz]

Quite old this topic but useful information now I am working on this.


I found out that a Solid created by the AutoCAD Command creates a more intelligent 3D Solid than I create with code. Do a list on both and you will see this:

Code: [Select]


                  3DSOLID   Layer: "0"
                            Space: Model space
                   Color: BYLAYER    Linetype: "Continuous"
                   LineWeight: Default
                   Handle = 145
         History = None
    Show History = No
   Bounding Box: Lower Bound X = 159.809  , Y = 159.747  , Z = 0.341
                 Upper Bound X = 198.179  , Y = 186.957  , Z = 4.638




Code: [Select]




                  3DSOLID   Layer: "0"
                            Space: Model space
                   Handle = 157
         History = None
    Show History = No
      Solid type = Sweep
     Sweep length: 38.867
 Profile rotation: 0.00
 Scale along path: 1.000
 Twist along path: 0.00
Press ENTER to continue:
             Bank: Off
   Bounding Box: Lower Bound X = 173.891  , Y = 144.954  , Z = -0.692
                 Upper Bound X = 205.943  , Y = 169.206  , Z = 0.692


So, the API probably just create a 3D Solid and AutoCAD can create a more intelligent object.


Also, and that makes it really weird, the coded solid get XData added! Why?

Code: [Select]

* Code 1071, 32-bit signed long integer: 2
