Show/Hide Elements

Views > Properties > Show/hide elements in view

Especially when displaying polyhedrons and freeform surfaces, certain edges that conflict with the rules of technical drawing need to be hidden. Edges are therefore assigned an internal ID, which identifies them as a normal or tangential edge, mesh edge in m-direction, n-direction, mesh diagonal or polyhedral lateral edge. Here, m and n are the natural parameter directions of a surface, e.g. latitude and longitude of a sphere.

Furthermore, this function enables you to show and hide assembly points, isolated points, weld seams and processing planes in the active view.

 

To be able to show/hide specific edges or to display them hidden, you need to know which Edge ID exists or can exist in which part type:

 

Edge type

Possible Representation

Centre lines

Centre crosses

Crosshairs and surface axes of various 3-D elements

  • Show
  • Overlap
  • Hide

Steel Eng. Axes, Tracing lines, Bar elements

Steel Engineering beams and profiles, Bar elements etc.

  • Show
  • Overlap
  • Hide

Free edges

Edges that do not attach to a surface and are not part of a composite edge. Free edges can, for example, represent a symmetry axis in solid bodies. Thread edges are handled like free edges.

  • Show
  • Hide

Hatchings

If you do not want hatchings to be displayed, deactivate this option. This setting applies to both 3-D surface hatchings and hatchings of sectional views, details and cut-outs. If the option is active, you can hide hatchings that would not normally be visible. Such cases can, for example, occur with sectional views.

  • Show
  • Overlap
  • Hide

Tangential edges

Edges the adjacent surfaces of which form an angle of 0 degrees.

  • Show
  • Hide

Polyhedron shell edges

Cylinder, cone (as polyhedron model)

Fillets (depending on generation)

  • Show
  • Hide

Weld seams

Symbolic weld seam edges

(has no effect on weld seams created with HiCAD versions before Version 2017)

  • Show
  • Hide

Assembly points

Assembly points (automatically or manually set points)

Please note that assembly points can be hidden globally by means of the functions Drawing > Others > Visual... and > Drawing > Others > Visual... > Assembly points OFF, respectively. If you have hidden assembly points in this way, they cannot be shown again with the function that is described here.

  • Show
  • Hide

Isolated points

Isolated points- also named points, symbol points and fitting points

Please note that isolated points can be hidden globally by means of the Drawing > Others > Visual... function. If you have hidden isolated points in this way, they cannot be shown again with the function that is described here.

  • Show
  • Hide

Mesh diagonals
Mesh in U-direction
Mesh in V-direction

Sphere, Torus: Latitudes (U-direction), longitudes (V-direction)

3-D revolved part, cross-section (V-direction), lines between cross-sections (U-direction)

Fillets (depending on generation)
  • Show
  • Hide

Processing planes

Processing planes - no sketch planes
  • Show
  • Hide

Cut edges

If the active view is a sectional view, detail view or a cut-out, you can specify here whether the edges between the section surfaces should be shown/hidden.
  • Show
  • Hide

The Hidesetting only affects the Glass Model representation.

 

Examples:


(1) Glass model, (2) Hidden line with lateral edges, (3) Hidden line without lateral edges

(1) All edges visible, (2) Without mesh edges in v-direction, (3) Without mesh edges in u-direction, (4) 30 degree limiting angle

(1) All edges on, (2) Polyhedral lateral edges off, (3) Tangential edges off

(1) All edges on, (2) Mesh diagonal off, (3) Mesh in v-direction + mesh diagonal off

(1) Cuboid with free edges, centre lines and crosshairs, (2) Free edges + centre line off, (3) Free edges + centre line + crosshairs off

(1) Top view with sketch for the section path, (2) Glass model with hatching, (3) Overlap hatching for a hidden line, (3) Do not overlap hatching for a hidden line

 

Please note:

  • The function only affects the currently active view. Multiple selection of views is not possible.
  • For assembly points and isolated points, hiding always affects only the existing points. This means that if further isolated points or assembly points are created, these will be visible. You must first recalculate the view in which the isolated points and assembly points are already set to Hide. To do this, use the functions found under Recalculate views in the context menu of the Redraw function.
  • Clicking opens a menu with further edge representation functions:

Hidden edges

defines colour and line type of hidden edges.

Highlighted edges

highlights edges in colour in Glass Model or HiddenLine representation.
In addition, the Show/Hide edges function can be used to show/hide any edges of a part in Glass Model and HiddenLine representation.
