Extending Lines to imaginary points
Read 4357 times
* May 18, 2014, 08:30:29 AM
What I am trying to do is to extend a line A  to the imaginary intersection of line A and line B (point C in the attachment.

So far I have only been able to extend lines if they would actually intersect the other object.

While I can make this work by drawing and deleting additional lines it seems to me that what I want to do would be very common.

Is there a way to do it?

Thanks,

Dave Davis

I use Geometric Aids for that. Extended Ortho and Apparent Intersection.

Right click on SNAP or GEO in the inspector bar and the Drawing Aids window pops up and you can set them there.

Maybe the "Modify / Meet 2 Lines" tool could help. It's good for connecting lines to lines or arcs. See the Snaps page in the Wiki or the Help to see how the two tools Bud mentioned can help visualize, prior to meeting.

Or you can select line A press V for vetex snap at the end you want to extend, immediately press X (seke to lock x axis) then vertex snap the line B end point and press X to unlock the x axis.

Thanks gentlemen but I fear I'm not making myself clear.

I simply want to extend Line A to point C which is the apparent intersection on Lines A & B.

I don't want to modify line B in any way.

Bud Lovel's post explains how.

Sorry; I misread the original problem.

My above post also does this.  By locking the x axis thie line will only move on the y axis, by snapping to the end of line B it puts the line A end point up the y axis to where line B is.

Though Bud Lovel's post would be a better way if you need apparent intersections on a regular basis.

I finally got it but it is so much more cumbersome than my old drafting program which just allowed you to extend a line to the apparent apparent intersection of the lines.

Turbocad only allows the Extend if the extended line will touch the other line.  It seems to me that it would be worthwhile to allow the line to be extended to the imaginary intersection of the two lines.

Perhaps I'll change my mind when I get more practice with this.

Thanks everyone,

I would use the " line length" tool with "apparent intersection" snap  enabled.

Another way...

Copy Line B "in place"; apply the Meet Two Lines tool (which will extend the copy of Line B); select and delete that extended copy, leaving the original Line B.

Hi delpi767.
 I show on the movie,  what is proposed  by Dean or Bud. Lines do not have to touch, one to second of them to extend in the way, what you want.  Swf file you can open in your web browser. I'm sorry if this is still not what you mean.
