There have been many discussions and posts regarding basic GDL creation. But I think to most people, GDL and even the Object tool in its entirety is generally thought of as a solution to 3D elements.
Custom GDL objects can be used to make drafting project details much more efficient. It can also make adjusting details more efficient. In the following detail there are several elements that are carried through several details, and the exact location of these elements can vary from one detail to another. The door rail hardware, roller shade, & caulking/backer rod can all be more easily placed and adjusted if they are saved as a GDL object in place of lines, arcs and fills.
Some things to keep in mind when saving a 2D detail object:
- Always place a fill behind the lines, arcs, & polylines before saving the object
- Always place hotspots at critical snap points for accurate placement and adjustment
- Default snap points for objects with no hotspots prior to saving are the 4 corners & center point only
- Take a screen shot of the detail elements before saving to use as a preview image
Now when adjusting the detail or drawing a new detail, the elements needed are in uniform objects capable of masking (using the fill) and can be moved, rotated or otherwise adjusted with a single click with no grouping needed. As an added bonus, there is a fill as part of the object so the element can be selected with a single click anywhere on the objects surface.
