The core Boolean features – unite, subtract, and intersect – are enhanced in NX 11.0.1 to better communicate non-intersecting bodies with error display.
The enhancements are summarized in the bullets below. The term “culprit” refers to an object that causes as error.
In the following example, you will see tool bodies subtracted from a target body. The gray body is the target.
Please excuse the academic examples. They are simple in order to illustrate the concept and not a reflection of my limited ability to model objects.
As you select tool bodies, the culprits – yellow, blue, and pink – will report errors indicating they do not intersect the target. As illustrated below, the culprits are displayed with the error color. The green tool does intersect the target and a preview of subtract is applied.
Notice that the target body is not displayed with the secondary select color. The single target body is obvious. Secondary display obscured the preview and, in combination with error display, produced more clutter than clarity.
In the following example, the blue tool intersects the gray target. The cylinder is tangent to the top face of the block; thus, it is coincident. Unite will succeed. Subtract will not. Subtract would produce infinitely thin volume where the cylinder is tangent to the face of the block. Error display is applied to the faces of the cylinder and the block as visual indication of where the coincident condition exists.
