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, processing planes, lettering and cut edges in the active view.

 

The dialogue window

 

The selected views are listed in the upper part of the dialogue window. After calling up the function, this is initially the active view or the current view list.

To select further views, simply click on the corresponding view frame in the drawing. If the frame of an already selected view is clicked again, the view is removed from the list. Alternatively, views can also be removed from the list by right-clicking on the corresponding entry in the list and then selecting the Remove element(s) from list function.

For the various elements, you can then select whether they are to be

shown,

hidden or

covered in HiddenLine mode.

The selected setting is always indicated by an orange frame.

 

	Switch to view selection
	The current settings can be saved as favourites and used again at any time. They are saved in the ProgramData\ISD Software und Systeme\HiCAD 2024\Favourites\VisGUI\ShowAndHideElements folder. You can find out more about favourites management here.
	This function can be used to adopt the settings of another view. To do this, select the corresponding view in the drawing.
OK	The current settings are applied to the selected views and the function is cancelled.
Apply	The function is cancelled without changing the views.
Cancel	The current settings are applied to the selected views. The view list in the dialogue window is emptied and the dialogue remains open.

 

Please note the following when making multiple selections of views (view lists):
If the settings of the views contained in the list differ, this is indicated in the dialogue of the function by a blue border around the corresponding setting.

Example:
The drawing contains a top view in which the centre lines are hidden and an axonometric view in which they are displayed. If you now select both views and call the Show/Hide elements in view function, the row Centre lines is outlined in blue and the text Different values appears on the info button.

 

The function is also available in the context menu of views and view lists.

Edge type

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 > Properties > Visual... and > Drawing > Properties > 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
Lettering	Lettering - for marking or numbering parts	Show Hide
Cut edges	If the 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:

 

Please note:

• 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.

• The presettings for this dialogue window can be changed in the Configuration Editor, at Drawing > Views > Hiding and overlapping of edges.
