TopoTools Palette
This tool palette consists of ten tools that help in the construction and analysis of topo drawings.

TopoTools and Topography Tools
The first topographical tools for PowerCADD were developed by Paolo Rossi in Italy. His external, known as Topography Tools offers a series of tools for placing topo points, slope interpolation as well as the import and export of topo survey data.

After seeing these tools, I began to develop some ideas on how topograpical tools might operate. Working with a number of civil engineers and architects, I have developed TopoTools and collaborated with Engineered Software and Paolo Rossi to establish a standard way to store a Z height and topo data in a PowerCADD drawing.

I regret any overlap of capabilities, and I urge everyone to investigate Topography Tools and the additional capabities it offers, particularly the ability to import and export survey data.

Z Height
A PowerCADD drawing consists of two-dimensional objects, however PowerCADD provides the capability to store additional information with each object. The Z height of an object is stored this way, and it is optional. Thus, most objects will not have a Z height at all.

To get started, use the Z Needle to assign a Z height to an object in the drawing. Once you do this, many of the tools in TopoTools will suddenly come alive when they ‘see’ the Z height of the object.

Dimension Point Objects
This is a new type of object which shows the X and/or Y location of the object in the drawing as dimension text. When the object is moved, the dimension text changes to the current X and Y location. The dimensions may be single or dual dimensions. The Dimension Point tool and Datum Dimension tool place dimension point objects in the drawing. These objects do not have a Z height, but you can use the Z Needle tool to give them a Z height.

Dimension point objects have a single marker, which can be literally any PowerCADD object, including groups of objects, pictures, etc. They are always a fixed size and are normally centered on the object, but not always—as in the case of Topo Point Objects.
These are a special type of dimension point objects which always have a Z height. As placed by TopoTools, the markers will be a reference point, or a vertical or diagonal cross.

Topo point objects may show only the Z height as dimension text, and may also have additional text for the survey point number and a description. While you may edit the survey point number and description with the Text tool, this will not work well because the text will be replaced with the original internally-stored point number and description.

The topo point dimensions may be single or dual dimensions. The topo point object may have a leader, which can be a polygon or a smooth B-spline.
