Snapping to 25%, 33%, ##% of a line's length

[Cradders]

Hello, another question!

Is it possible (through snap points or expressions) to draw a line that is a specified percentage of another line's length? I don't want to reference a specific line, but say, the line that is currently selected. I am making a UDF that is based on the selection of a line and want to generate a line that is a certain percentage of that line.

Thanks,

James

Hi,
if you are sure you will deal with LINES only, one thing that comes into my mind is to create a first point entity at 0% length (t=0), then a second one at xx% (t=0.xx), then create a line between these two points.
Certainly in the myriad of UG tools there is something better than what I described...

Regards

Not without first creating a measurement expression linked to the length of the first line.

If you know how long the line is then by using the reference method and distance along a line sure, just type the calculation under the length expression as you go. It wouldn't be something that you want to do frequently but I expect the need would not be very common.

Best regards

Thanks guys, I'll have a look at the t=0.xx method.

Cheers!

Expressions are the way to go.
