The list of third party components available to ODA members (ACIS from Spatial, HOOPS from TechSoft3D, Adobe-Based PDF) has been extended with the Constraints Support from LEDAS.
All ODA members can now integrate the LEDAS LGS 2D geometric constraint solver with a Teigha for .dwg files client application to provide easy access to constraint solving functionality.
A sample application demonstrating a number of constraint-related features can be found on the ODA web site. The demo implements the following functions:
- Load a drawing file containing constraints, and render the drawing.
- Add constraints to a drawing file.
- Move geometry on the screen, when the mouse is released all geometry is updated per the constraints contained in the drawing.
- Edit distance or angle parameters, causing constrained geometry to be updated automatically.
