3DP_FOCUS_STUDY_REGION [Public Dialog]

Package: 3d-printing (Nick name(s): :3dp)

Focus on a region of a mesh quality study by showing only items in a specified region of interest (box) or with similar geometry.

Study Region

The dialog offers two complementary approaches for filtering down the measurement to a manageable size:

While the dialog is active, both approaches can be used in an alternating way to interactively switch between box or geometry filtering.

It might be handy to also load the original CAD model for reference, but it is not required. The study contains a copy of all relevant faces from the CAD model.

Dialog Options

  1. A mesh study container generated by the dialog 3DP_MEASURE_MESH_QUALITY (Measure the quality of a mesh with respect to the part it was derived from). See option :STUDY below.
Focus Region (By Box)

Use part or assembly boxes to focus on a region of interest.

  1. One or more parts or assemblies from the Measurements sub-assembly in the mesh quality study container associated with a mesh. The bounding box of the selected parts / assemblies define the region of interest to focus on. You can use the structure browser for selection, pick, or use the measurement browser (recommended). See the Measurement Browser section for more details. All parts from the mesh quality analysis which fully lie in the region of interest are drawn, all other parts are hidden. See option :STUDY_PARTS below. Parts not contained in the region of interest are hidded (see illustration item 14 for an example).
  2. The inflation amount for the region of interest. The amount is calculated by increasing the bounding box up to the size of the entire measurement result. This is used to add more context to your focus region. See option :REGION_SIZE below.
  3. Display filter to show/hide warning facets. See option :SHOW_WARNINGS below.
  4. Display filter to show/hide error facets. See option :SHOW_ERRORS below.
  5. Display filter to show/hide error facets. See option :SHOW_MODEL below.
  6. Display filter to show/hide the mesh. See option :SHOW_MESH below.
  7. Display filter to show/hide the feeback box of the region of interest. See option :SHOW_BOX below.
  8. Re-apply the region-of-interest filter.
Filter Parts by Geometry

Use geometric rules to focus on faces with similar geometry.

  1. A reference model face to be used as a template for finding faces with similar geometries. One a face has been selected geometry specific matching options appear.
  2. Show the number of matching geometries and to open the Measurement Browser which is described in the next section. See option :GEOMETRY_NUMBER below.
  3. Reapply the geometry filter. See :REAPPLY_RULE below
  4. Clear the geometry rule based filter.

The Measurement Browser

The measurements browser is activated by pressing the Matches button_ (see previous section). It shows measurement errors and warnings associated with model faces. Geometry filters, as described in the previous section, can be used to reduce the number of measurments shown in this dialog.

Measurement Browser

  1. List of measurements associated with model faces. Select individual measurement rows to show error details in the Mesh Errors pane (2) and focus on that measurement in the graphical display. The area column shows the accumulated area of the measurements error facets so that insignificant mesh errors (tiny face areas) can be detected quickly.
  2. List of mesh error parts of the measurement selected in (1). On selection the region of interest is set to the chosen error. The CAD model face and the associated facets are then shown in the graphical display. The area column shows the area of the individual groups of connected error facets so that insignificant mesh errors (tiny face areas) can be detected quickly.
