I am pretty new to OmniGraffle and this seems like a pretty easy thing. However, I must be blind to figuring this out.

I would like to combine two lines together into one longer line. However, nothing I do solves this.

The above file shows what I am talking about. There are three different lines, but I would like to combine these lines into one long line. There is a way to do this correct?

I thought about adding midpoints. However, that doesn't get the length of the line the extra size that I want. I would prefer to be able to set the length of each line, then combine all of the points.

Can this be done?

Why on Earth would you want to do that ?

OG handles lines perfectly. You need to learn to use he tool. You're used to using a hatchet ,now you've got a small, precise chainsaw, but you still want to use it like a hatchet.

1 Change the length of any line:
- by clicking on any end-point (that the same as a mid-point) and dragging it
- select the line and change its dimensions and position in the Properties:Geometry Inspector
2 Change the various aspects of the line (includes double-stroke) using the Style:Lines and Shapes inspector. Learn every property, and its effect, in this inspector.
3 You can really hot on the dance floor if you learn to use Magnets. First understand them on shapes (rectangle, etc), change the number, make your custom Magnets. Then work with Lines, connecting lines to shapes. Then learn that for Lines, every mid-point and end-point is a magnet. My last example show what happens when I pick up the horizontal single line an d move it (the double-stroke is attached it it, at the middle, a mid-point).
4 Depending on your need, you can setup the grid, and have all you end-points and mid-points aligned to it.
5 Drawing what you want with elegance is simple in OG (seconds, no "fiddling" time when you want to make changes). But if you use it like a hatchet, you'll get a broken matchstick diagram. If you really want to draw line fragments, and join them up correctly, which is no problem at all, just slow, you can do that (minutes). But you still need a decent run through the above. Otherwise about 10 min per complex line to draw, plus unpredictable fiddling time every time you want to change it.

That is why I am writing the board. My problem seems to be that geometry tool only allows for me to make precise lengths with the entire area that the line consumes, and not the individual pieces of the line. If I could figure out how to manipulate the individual lengths of the lines, it wouldn't be a problem.

In the above diagram, you will see a line segment that has a start and end point. However, via the geometry tool, I can only modify the entire box. Not the length of the start and end point to the corner.

Thanks for responding and helping me learn the program.

My pleasure.

There seems to be something I am missing, we are not on the same wavelength yet. Have you followed my suggestions ? They provide good methods of working with a single line with many mid-points, as well as complex objects made up of simple line frgaments (which you can manipulate exactly).

In the above diagram, you will see a line segment that has a start and end point. However, via the geometry tool, I can only modify the entire box. Not the length of the start and end point to the corner.

(It is a single line, not a box.) I do not understand what the problem is. So in that one step you can't use the Inspector, so what. In [1] above, there are two options: depending on what you want to achieve, one option is better than the other. Just pick up start- (or end-) point and drag it to where you want it to be.

It is simpler than you think.

Make sure you Command-click on the thumbnails below, examine the full detail, and understand the distinction between:
• start-points and selected start-points
• end-points and selected end-points
• mid-points and selected mid-points

Or double-click anywhere on the line to add another mid-point, then drag the mid- or start- or end-point.

If you decide you do not want a particular mid-point or the start- or end-point, just select it and hit delete.
