Object Properties

Following properties can be set via Menu-options.svg Properties Dialog.

Visibility

You may show or hide objects in the Menu view graphics.svg Graphics View in different ways.

  • You may use tool Mode showhideobject.svg Show_/_Hide Object Tool to show or hide objects.

  • Open the Context Menu and select item Mode showhideobject.svg Show Object to change the visibility status of the selected object.

  • In the Menu view algebra.svg Algebra View, the icon to the left of every object shows its current visibility state (shown or hidden). You may directly click on the little marble icon in order to change the visibility status of an object.

  • You can also use the Mode showcheckbox.svg Check Box Tool in order to show or hide one or several objects.

To make an object "invisible" in the Menu view algebra.svg Algebra View, make it Auxiliary.

Fixed objects

You can define an object to be fixed via Menu-options.svg Properties Dialog. Fixed objects (both free and dependent) cannot be moved. To stop an object being selected / deleted you can uncheck its "Selection Allowed" option in the Advanced Tab.

Filling

For closed Curves and regions you can specify filling using the Style tab of Menu-options.svg Object properties dialog. There are three types of filling:

Standard

Fills the object by color specified in the Color tab. The same color is used to draw border of that object. Using Style tab you can define opacity — e.g. Conics have by default opacity 0 which means they are transparent.

Hatching

The object is hatched, angle of hatches and distance between them can be specified. Thickness of hatches equals the thickness of object’s border.

Cross-hatching

The object is cross-hatched (available angle for hatches: 0° - 45°) and the distance between lines can be specified. Thickness of hatches equals the thickness of object’s border.

Chessboard

Fills the object using a chessboard pattern (available angle for squares: 0° - 45°). The squares' heights can be specified.

Dots

Fills the object using a dotted pattern, distance between dots can be specified.

Honeycomb

Fills the object using a honeycomb pattern, distance between the cells can be specified.

Bricks

Fills the object using a brick pattern, angles and bricks' heights can be specified.

Weaving

Fills the object using a weaving pattern, angles and spacing can be specified.

Symbol

Fills the object using a special symbol chosen from a list, distance between symbols can be specified.

Image

You can specify location of image on the local disc. The image is repeated periodically, its size is fixed in pixels and top left corner is aligned to the top left corner of the view.

You can also check the Inverse filling box to fill with the selected pattern the whole Menu view graphics.svg Graphics View, except the selected object.
