I'm sorry, I must be terribly dense. Well, actually, just trying to wrap my head around the procedures in MOI. I can't figure out how to use that nifty plug-in.

I drew a couple of lines on one plane, and then activated the plug in to MarkUnmatchedCurveEnds, but I couldn't see anything happen on the drawing. I could click on the lines and they turned yellow, but nothing else. Didn't matter if they intersected or not.

When I launched the plug-in, an information box popped up in the upper right, which SEEMED to be asking for an input (i.e. "Tolerance") but I couldn't figure out how to use that box. No amount of clicking anywhere in that box did anything.
And then the computer "hung" for half a minute... I was almost ready to do a hard reboot when it finally came back.

Michael, you have my great respect. You obviously know the API for MOI inside and out; I looked at the JavaScript and although I don't understand it, it's obviously a masterpiece of object-oriented programming. Are you one of the developers of MOI?

If it matters, my computer is running Windows 10.

Normally you have that...

u'r commad ui looks weird, it should be an input box(css problem)
about tolerance
(1/3)*3 != 1 -> there will be a margin error - tolerance is that margin error after all moi curve's calculations

Tim,
I dont know how to solve your issue but you seem to be in
need to often zoom in at point level.
There is a script from Michael which is helpful to zoom in
quickly to point level with just one keystroke.
Does not solve your problem but speeds up the process
of zoomng in.

Jay,

So you have a bunch of curves whose ends meet at one or several shared common points -
you can download the example I attached at the beginning of the thread.

Now you select them all.

Run the script.

One or more points will be created by the script command where the curve ends
do not match perfectly. Thats it.

You can turn on select points to get them in the yellow color to make
them easier to identify

Yes, Cemortan_Tudor, I agree it's a UI problem.
I notice the script uses HTM and JS. Does that mean it actually depends on my browser? If so, maybe there's a browser setting I need to change?

Hi Jay,

re: Can't run script - what version of MoI are you using? It looks like you may be using version 2? If so then that's the problem, that version is really old. It was released more than 10 years ago. You would need to update to the current version to run this script.

re:
> Are you one of the developers of MOI?

Yup!

Michael, you are a genius. Yes, I'm on Version 2. I have sent a query to Alibre to see if an upgrade to V3 is included in my Alibre subscription.
