(6) develop a simple CAD solution step by step

To achieve pick-up, you only need to select the objects in the entity set to pick up the collection.

The mouse goes through the object set is a brilliant color, and the mouse selects the object is

Select an object from the object, and then add it to the selection set.

Therefore, a class is developed to operate on entity tokens and selection sets.

 

Typedef struct // Index Related to object pointer
{
Csolid * m_picksolid;
Int index; // The Index associated with the pointer

} Pindex;

Typedef ctypedptrarray <cobarray, csolid *> tagcarray;

// This class operates on the object set and select set, including
Class chandlecg // operation dataset. You can extract specific elements from a set and put them in another set.
