Powerpoint: manage lines with connectors

Hello experts,
I am trying to find an effective way to manage lines in powerpoint.

I identified two problems:
1-In powerpoint you cannot connect your lines objects, but you can do it for shapes. As a result there is always an space between each end and beginning ie : blue ovals:
2-If you want to re-size vertical & horizontal lines I grouped them however given that the vertical line is an horizontal line with 90° rotation I cannot properly re-size it.

Thank you in advance for your help.

Use the Align Tool?

I've done this with a vertical and horizontal line in Slide 1 of your attached pptx then rotated and reduced the image in size.

Was that what you were meaning?

An answer to part of your question: the gap between a vertical and horizontal line is probably the result of the cap type on each line. The default is usually "Flat". Select both lines, right-click on one of them, select Format Shape, and then change the cap type to "Square" -- the gap should disappear.

Thank you for your your comment.
Scott, if after selecting square cap how to connect automatically vertical and horizontal lines? Or should I move manually to connect both lines?

You still need to place the lines manually. The square cap simply hides the gap.

If you draw a horizontal line and then draw a vertical line (as opposed to rotating the horizontal line to create a vertical) then you can group the lines and size them using the height and width boxes. Works for me, anyway. It's not always perfect, but it's certainly better than if I rotate a horizontal to create a vertical (or vice-versa).

I do recommend changing the cap type to square, as was already suggested. I also zoom into 400% when I'm putting them together before grouping. Also, sometimes they'll look off in editing mode, so be sure to look at them in slide show view (or while zoomed in more than 100%) to see if they're still connected as you expect.
