Line that extends both ways
Read 4052 times
* August 26, 2019, 03:07:03 PM
I would find it very handy if the line tool could have an option selectable to make the line extend both ways similar to how the 2 sided extrude tool works in 3d. I find myself always starting a line at a vertex and then snapping to another vertex of unknown length and then using the line extend tool to make it go the other way also. On other occasions that I know the distance and angle I will just draw the full length line and then pick it up by its reference point and snap it on to an entity to make it go both ways from midpoint. I think a separate line tool that would do this wouldn't be as handy as just an option on the regular line tool.

Yes, I had often thought this might be helpful.
The same idea could usefully be extended to rectangles?

I'd like this, too.  Every once in a while, I could use the ability to start a line at its mid-point.

While you're at it, I would also like to be able create an Arc essentially the same way (center, then mid-point of the arc, then one end-point).

It's already there; use the Polygon tool with 4 sides in ‘Vertex’ mode. Unfortunately, you can't set it to 1 or 2 to make a Line starting from the middle. Maybe they can add a ’Vertex’ option to the Line tool.

Take a look at TurboCAD's LTE Tools available in regular TurboCAD. It has several different methods for creating an arc, though I'm not sure if they will work as expected in regular TurboCAD.

My menu is customized.

Hi John,

nearly, but no cigar!   ;D

See attached, of the basic idea. 
It's the profile of a table, say, and I want a rectangle hanging from the tabletop to represent a drawer, not necessarily filling the space between the table legs. 
Now, by snapping to the midpoint of the tabletop lower edge, a drawer profile is easier to construct, if what I suggested above were possible.

Okay, a picture is worth a thousand words; so much for that idea.  :(

I was sure TurboCAD had added that at one point, but them remembered it was SolidWorks that added that a few versions ago. Hard to keep it all straight sometimes. A handy tool to be sure. It would also be nice if we could add equations in the inspector bar, say like 15.125/2 or 15.125*2 or 15.125+ 1/16, etc..

When you tab into a field, hit "F2". This will open the Calculator palette and you can input your calculation, then Enter. Your calculation result should be back in the input field. I would use "Ctrl+L" at this point to ‘lock’ that result in place before you go to the next field (TurboCAD has a bad habit of going back to the previous number). Use "F2" in the next field and so on.

Well, how about that. I don't recall ever knowing this. Is it okay to say it sounds a bit cumbersome, but that I still appreciate the option? Thanks John.  Going to try this now......

It never occurred to me that I could do that.  Will have to experiment tonight.

Here's a list of the "Draw" tool commands found in regular TurboCAD and their Descriptions. It may be of some help.

Lines will lengthen both ways in node edit if selector mode and keep aspect ratio are enabled.  Select both nodes, pick up one end and the other heads off in the other direction.

That works, but you can't spec a length of an angled Line. If I go to the "Length" option in the Selection Info palette, it extends in one direction.

If I need an existing Line to go a particular distance both ways, I'll use the "Line Length" tool. Input a "Delta L" length, then "Ctrl+L" to lock that value. No Snap (S) twice on each end to ‘select’ and ‘set’ the new length.

You guys have brought out some great tips! I am glad you have all responded. Perhaps they will add this in the 2020 release. One could certainly hope!

If I needed to define the length numerically I might do that, although TBH until I read your post I didn't know that there is a line length tool, I would've copied in place, set the new length, picked it up, snap E or M to the original centre of extents and delete the unwanted line.  Another way to do it graphically is transform scale with keep aspect ratio checked.

See attached video.
This can be useful sometimes.
I think I reported this as a bug many moons ago because as John R says when the line length is changed from the selection info palette the line extends from the 1st vertex  ::) so there are two way to change the length.

Doesn't work for lines that aren't ortho, Dean.
