Co-ordinate Block Place

The Block Place options allow users to place a copy of a co-ordinate block into a model. These options can be used to represent anything from the footprints of houses to a full survey. 

Note that the Block should be generated in the first instance via the "To Block" option under the List menu. This generates the block from the contents of the List, but also prompts users to specify the Origin and Direction points of the block to ensure it can be correctly inserted via the "Block Place" command at a later date.

There are three options presented in a simple pop-up menu.

1 Point: Allows users to simply specify the origin for the points.

2 Point: Allows users to specify the origin and orientation of the points.

3 Point: Allows users to specify the origin and orientation for the points together with a third point specifying the side to which the points will be created.

When one of the options is selected, the Co-ordinate Block Place dialog will be displayed. This allows the user to select the points to place and the method by which the point heights will be assigned. There are six possible options in the Height Method Group.

Assigned: This option uses the heights that the points already have in the co-ordinate block.

Constant: This tool allows users to insert a height value in the Constant Height box and it will be remembered for the next time it is used.

Relative: This option uses the heights from the points in the co-ordinate block but offsets them by the value in the Delta field.

Origin Lock: This option uses the height difference between the block origin and the indicated origin point as a relative offset for all the new points.

Typed: This tool uses the same height for each point and should be entered in the Height field which will be enabled.

Indicate Text: This function allows users to place the block and then indicate the height by clicking the CAD text in the backcloth.

Once the block has been selected and the height calculation method has been defined, users will be asked to indicate the appropriate positioning points. Users will be prompted to indicate each point and simultaneously, they will be shown a preview of the co-ordinate block in a simple line form.
