Options in the Format drop down menu are briefly described here. Please click on the fly out menu items for more information.

Format menu


This tool enables users to create new layers, control the colour, linetype, line thickness of layers. If you want to change the stacking order of entities on a layer see the Tools menu.


A linetype defines a line's characteristics. A line can consist of combinations of dashes, dots, spaces and symbols. New entities are added to a drawing using the current linetype. When you create a new drawing it already has linetypes named "ByLayer", "ByBlock", and, "Continuous".
The LINETYPE command shows the dialog box below. gCADPlus allows the use of AutoCAD .lin files. These can be loaded using the 'add from file' option in this dialog box.

Line weight

Lineweights add width to your objects, both on screen and on paper. Using lineweights, you can create heavy and thin lines and vary object thicknesses in details. Just as heavy and thin lead weights are used in manual drafting, lineweights can be used to graphically represent different objects and types of information. The figure below shows a thicker line being applied to the walls and thinner line thicknesses to other entities.

You should not use lineweights, however, to represent the exact width of an object. For example, if you want to draw an object with a real-world width of 1.5 millimeters, you should not use a lineweight; instead, use a polyline with a width of 1.5 millimeters to represent the object accurately.

Lineweights are displayed differently in model space than in a paper space layout. In model space, lineweights are displayed in relation to pixels. In a paper space layout, lineweights display in the exact plotting width. Lineweights should be used for the graphic representation of different objects and types of information, and are, therefore, displayed in model space in proportional pixel values. You can recognize that an object has a thick or thin lineweight in model space but the lineweight does not represent an object's real-world width. A lineweight value of 0 is displayed as one pixel in model space and print at the thinnest lineweight available on the specified printer. All other lineweights are displayed using a pixel width in proportion to its real-world unit value.

Lineweight display in model space does not change with the zoom factor. For example, a lineweight value that is represented by a width of four pixels is always displayed using four pixels regardless of how far you zoom into your drawing.

You can set the display scale of lineweights if you want the lineweights on objects to appear thicker or thinner at model space. Changing the display scale does not affect the lineweight plotting value. However, a drawing's redraw time increases with lineweights that are represented by more than one pixel.


All colors used in gCADPlus are stored in a table called the "Color palette". Each color of the palette is an RGB value. The palette can be loaded and saved to/from disk file. The Color value of a gCADPlus object is an index value of the palette. An entity uses an index value ranging from 1 to 255 or the color is specified "ByLayer" or "ByBlock".
"ByLayer" means the color assigned to a Layer will dictate the color of an entity found on that particular layer. "ByBlock" means the color assigned to a Block will dictate the color of an entity added to a Block Insertion entity. If the entity is not a part of block but has the "ByBlock" color assigned to it, the white color (7) will be used to draw the entity.
Custom colors can also be added via the Options tool.

Text Styles

A wide range of text styles can be created. We favour the use of hand written styles. a number of these are pre-loaded in templates.

Point styles

A point is a single entity with a fixed coordinate position.This command enables users to change the appearance of the point style marker.

Dimension Styles

Dimensions can be taken automatically from the model. This option allows users to set up personalized dimension styles, modifying such things as arrow heard type, text style, offsets from model etc.

Multiline Styles

It is possible to draw complex commands after a style has been set up. A multiline style might be used to draw a double brick wall.


Calls the Image manager where images can be attached to or detached from the drawing.


This option is used to set up layout sheets - views of the design or parts of the design on drawing sheets.


gCADPlus drawings are full size. This option allows you to set up your usual drawing units for scaling insertion of objects (mm or decimal feet being the most common), rotation angle, desired precision etc.


Adjust the area available for drawing.


Used to make a block (collection of entities grouped together). Identify a base point and provide a description.


Review (browse) blocks associated with a drawing. Search for blocks outside the current drawing and insert into the current space if required.
