About Clipping

Clipping is a depth effect for viewing parts or all of a 3D object between two planes. Clipping of entities may happen in many scenarios of VECTOR printing.

Examples are:

  • Drafting: an entity might be clipped by a view with visual clipping.
  • 2D Layout: an entity might be clipped by a cutting plane, a clipping frame, a circular and polygonal clipping view, or a back clipping plane view.
  • DMU Space Analysis: an entity might be clipped by a DMU clipping plane.
  • An entity might also be clipped if it partially gets out of the target print paper.

Markers

The markers (that is, the point representation) are clipped according to the center point position.

Therefore:

  • If the center point is outside the clipping planes, the marker does not appear on the plot.
  • If the point is inside the clipping planes, then:
    • If the marker is totally inside, its representation is totally plotted.
    • If the marker is only partially inside, its representation is partially plotted.



Texts

A text element that is partially clipped might be tessellated depending on the destination format (PDF, SVG, PS, CGM , HPGL2, etc.) and whether the clipping is straight or angled.

In that case, only the text tessellation (triangles) is dumped in the output file. The text string and font name are not dumped.
