## Getting Precise With Steve

I am Dr. Mesh and designing is not my cup of tea. Yet somehow, I was roped into, ahem… asked to do a design job. As luck would have it, most of my colleagues were on holiday when my boss ordered, ahem… suggested that I create a more efficient system.

Efficiency is my middle name, but I had to start from a Part that one of my colleagues created earlier. Of course this was one of the aforementioned colleagues, now sunning himself on a beach in Papua New Guinea. I was stuck. I had to know the exact coordinates of a set of faces to continue the project.

I know how to extract coordinates by probing in a Scene and hitting the “.” key, but in this case I needed to know the entire geometric range of the faces of that Geometry Part.

Again I checked with my ol’ buddy Steve, who helped the last time when I had to Find a Trend Among Chaos. Again, Steve did not disappoint. I logged in to The Steve Portal and found the following article. It was exactly what I needed to avoid disturbing my colleague’s much needed “rest”.

Office relationship saved and brownie points earned for completing the project on time and under budget. For this, they best bring me back something more than a stupid t-shirt!!

How to Measure the Geometric Range of a Part
It is possible to measure the exact position of a geometry part, even if no region or volume mesh are assigned to it.

1. Right-click on the Geometry Part which you would like to evaluate, and select “Repair Surface...” in order to open the “Surface Repair Tool”.
2. Select “All faces” to be shown in the pop-up window.
3. To measure the coordinates of the surface, navigate to this surface, and select all the faces by double-clicking the surface.

The selected surface is then highlighted, as shown in the following picture:

1. The geometric range of the selected surface and associated faces can be obtained by clicking the following button:

1. The geometric range appears in the “Output Window”.

If the selection contains a mixture of Faces, Edges and Vertices, the “Mixed Query Mode” can also be used to evaluate the geometric ranges. This “Mixed Query Mode” can be found in the context menu by right-clicking the “Geometric Range of the Selected Faces” button.
