The Block Place options allow you 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 that Block should be first generated via the "To Block" option under the List menu. That generates the block from the contents of the List, but also prompts you to specify the Origin and Direction points of the block so that 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 you to simply specify the origin for the points.
2 Point - allows you to specify the origin and an orientation for the points.
3 Point - allows you 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 you select the points to place and the method by which the point heights will be assigned. There are four possible options in the Height Method Group.
Assigned - uses the heights that the points already have in the co-ordinate block.
Typed - uses the same height for each point and should be entered in the Height field which will be enabled.
Relative - uses the heights that the points already have in the co-ordinate block but offsets them by the value in the Delta field.
Origin Lock - uses the height difference between of the block origin and the indicated origin point as a relative offset for all the new points.
After you have selected the block and defined the height calculation method, you will be asked to indicate the appropriate positioning points. As you are asked to indicate each point, you will be shown a preview of the co-ordinate block in a simple line form.
