How Long is This? Getting Polyline Lengths out of the Properties Panel and into your Table File.

I've been doing some work planning trench traces for an early exploration project. Below I have some parallel trenches/sampling lines. I'd like to know how long these lines are. We know that selecting a polyline can bring up the properties. We also know the Measurement tool can help. 

What if I want to get the lengths of many lines, and have those lines attributed to the polylines themselves? If you're a new Origin user, you might just open the properties for each line and type them into the table file directly. That's not bad if you have a few lines, but what if you have 100s of lines that need to be measured?

Look no further than the Desurvey String tool! You'll find it on the Design ribbon:

You can set it up with your input file and have several options of information that can be output to your .STR file.

I want the total line length, so I will type "Line Length" in the field next to Cumulative Length. This creates a new header in the input file where the length will be stored. I've also opted for a Segment aziumuth value to be stored under "Line Azimuth":

After I run the tool, we can examine our input file and see the line lengths and azimuth stored for each line in my file:
