17 | |
18 | ---Purpose: |
19 | -- The basis to define a point attribute. |
20 | -- The topological attribute must contain a vertex. |
21 | -- You use this class to create reference points in a design. |

23 | -- Warning: Use TDataXtd_Geometry attribute to retrieve the |
24 | -- gp_Pnt of the Point attribute |
