A block is a single gCADPlus entity usually containing many other entities inside it. A block has a name, optionally a description and can simply be made up of a few lines and circles, or as complex as (say) a design for a complete courtyard. Symbols used to indicate the position of plants in a design are examples of blocks.
gCADPlus contains many in-built blocks that are reached (and inserted) via the Library drop down menu.
The figure below shows the gCADPlus Library drop down menu.
Tip: A number of the templates available when the New option is chosen to start a project also contain additional blocks.
The figure below shows the result of navigating to the sized group above and to the tall trees section within it. A block selection dialog box is open and the block called UPlantTallTree10 is highlighted (selected). A preview of the contents of the block shows at the right.
Tip: This block is in fact a separate gCADPlus drawing and is inserted into the drawing when you select the open option.
In the figure below, the UPlantTallTree10 symbol is placed into the drawing. In the figure, once in place, it remains selected.
Examining blocks in a drawing
There are a number of ways that can be used to determine the blocks in a drawing. Selecting the BL icon on the Format toolbar is perhaps the easiest.
When selected, this BL option throws up the dialog box shown below. You can think of this dialog box as a block browse facility. Much useful information is displayed including the number of entities contained within the block and the number of instance of the block in the drawing.
The block can be renamed, edited or inserted into the drawing.
Creating a block in a drawing
The figure below shows that we have selected a circle and some lines and are about to make a block suitable for indicating a Grass Tree (Xanthorrhea spp)
Each block symbol can consist of elements on different layers. This enables the production of several plans from the one drawing, just by a mouse click, turning layers on and off as needed. Reusable symbols are of great value when it comes to details that normally accompany landscape drawings.
Blocks can be edited 'on the fly' using Block Edit. Make changes in the block and watch those changes being reflected in every instance of the block.
