Hi Michael,

Is there a way (shortcut) to have a point with known distances from 2 given points on a standard view?

Thank you,


George

If you create 2 circles you can then find that point using intersection snap.

I'm not really sure if there is much possibility to make it any shorter than that, because you need to identify the location of P1, and the distance of L1, and then the location of P2 and the distance of L2.

Creating 2 circles is the same number of picks as that, pick the location of P1 for the center of the circle, and type in L1 for the radius of the circle, pick the location of P2 for the radius of the 2nd circle, and type in L2 for the radius of the 2nd circle...

Hi Michael,

Thank you for the immediate answer.
Right now I use this solution, as you can see in the attachment, but I ask for an automated way because most times I have many points estimating triangles from field measurements.

George

Hi George, could you describe how you would want an automated method to work?

I can't see how an automated method will be able to do it in fewer picks - don't you need to pick 2 points and enter 2 distances? That's the same number of picks for creating 2 circles...

Hi Michael,

The most annoying step is that you have to delete 2 circles and then go to the next pair of points and so on.

Thanks again.


George

PS. Wish I have construction circles..

circles "helper lines" will be fine ;)

Well, the only alternative short of a whole "construction circle" mechanism (which is not really possible to do as a plug-in, it would need quite a bit of internal support stuff for that), would seem to be to make a plug-in that creates 2 point objects, since there are actually 2 possible solutions where the 2 circles intersect.

So it's either delete 2 circles or delete 2 points...

Would it help any if there was a command to delete the last 2 created curves so you could do that with 1 keypress without needing to actually select them?

hey george

you could use the SelectClosedCurves for a tinytiny workflow-enhancement

http://kyticka.webzdarma.cz/3d/moi/#SelectClosedCurves

it selects all closed curves, so it doesn't bother with points and lines..

your work flow would be something like this

1. draw circle 1 -> radius
2. draw circle 2 -> radius
3. pick point -> intersection 1 or 2
4. SelectClosedCurves -> delete

Hi all,

Thank you for your solutions.

Michael,

I think is better to have 2 points , since one will be used (the remaining point(s) does not complicate the plan).
Probably a selection between them, about the side, will solve it.

Thanks,


George

< it selects all closed curves, so it doesn't bother with points and lines..

yes but it's not dangerous?
If another closed curves than circles are existing anywhere in the screen?
They will be killed also ;)

it's dangerous..that's for sure ;]

so just a little selection by rectangle right to left is maybe speedy and sufficient
before the circles helpers lines :) (if they come a day in the v3 ;)

I should be able to set something for that up.

Would a command that had a sequence like this work:

Pick point P1
Enter distance L1
Pick point P2
Enter distance L2
Pick point, intersection point closest to the picked point is taken.

Or would you want a different sequence, like pick both points first and then enter the distances?

- Michael

Hi Michael,

Your sequence

>Pick point P1
Enter distance L1
Pick point P2
Enter distance L2
Pick point, intersection point closest to the picked point is taken.<

will be the best.

Thanks,


George

Hi George, I've attached a plug-in here that you can try.

To install it, download the attached .zip file and unzip it, then copy the 2 files to the \commands sub-folder inside of MoI's main installation folder.

That will then make a new command called Intersect2Circles available. To trigger the command, set up a keyboard shortcut under Options > Shortcut keys, and for the command part of the shortcut put in: Intersect2Circles

Then when you push that key, this custom command should start and it works as described above. It lets you create 2 circles and then at the last step you pick a point to tell it which intersection you want to take.

For the last pick you just need to pick a point closer to one of the 2 possibilities, you don't need to actually put it at the intersection although you can if you want.

The circles will be displayed only while you are inside of the command and when you are finished only the single point will stick around and the circles will disappear.

I hope that might help for processing a lot of these!

- Michael

Works like a charm! bravo!

A little trick if you dont make a another shortcut and don't want re type the command
Type one time, copy it then just copy past it for the other time ;)

PS
I obtain an error message when I draw first point in Top view, second point in Front view
Seems your script works only in the same window and not with circles not coplanar ?

Hi Pilou,

Also if you just want to repeat the last command that was run you can do that by right-clicking in a view port or pushing the Enter key after the command has finished.

Yes, the circles must be coplanar and also intersecting for this command to work properly.

- Michael

ah yes the right click :)

Hi Michael,

Works like a charm. Thank you very very much for your effort to make this plug-in.

George

You're welcome George!
