Ensuring the angle between two lines is 90 degrees

[lovelyjubbly]

Hello - I'm a newbie to AD, and I think I need to use the construction snapping tool, but the instructions in the manual are pretty vague and I can't see what I need to do. How do I ensure that the angle between two lines is at 90 degrees?  There's a "square" node between the two lines, and I can rotate the object and use the guides, but I'm sure there must be a simpler way. For example, I want the angle at the bottom left to be 90 degrees.

Thanks for being understanding about the dumb question!

Thank you 🙂

I don't know if this will get you what you're after...

• Select the Bottom-Left & Top-Left Nodes. With the Node tool, you can marquee select them or Shift +Click each one.
• Go to the Transform Panel. By default it lives at the bottom right. If you can't see it go to Window>Transform, and select it if there's no check beside it.
• The bottom left of the Transform Panel, is a field, R, which stands for Rotation. Just selecting those nodes in your shape, it should have some number showing. Try typing in 90. I think that should make the angle of the bottom line and left line 90°

Thank you Ron, that doesn't seem to do anything for me.  Highlighting those nodes does not allow me to enter anything in the rotation box.  Thanks anyway!

That didn't ? Here's what I think you're wanting to do. If not could you provide a screen recording of what it is you're trying?

thanks Ron - what I want is for the bottom line to emerge front the almost-vertical line on the left hand side at a right angle ie there is a right angle in the bottom left hand corner.  The bottom line then needs to curve so that it meets the almost-vertical line on the right hand side, also as a right angle, like this.  I don't know how to do screen recordings sorry.

Ok, gotcha!! I'm not sure it can be done. I'll have to play around and see what I can come up with. In the meantime hopefully someone with more expertise than I will come along with a solution or definitive answer..

Thank you for your help!  I can "bodge" it by tracing the vertical lines and then rotating them 90 degrees, then moving the nodes on my original curve to match. It works but is quite cumbersome and I hoped there would be a faster way😊

Made a video of my idea to get right angles on acute corners, still convoluted but guaranteed right angles 👍

That is SOOO cute, love the little Pacman approach😊👍

@firstdefence I guess we could use your method to set any angle by setting it in the Pie tool's Context Toolbar. I am running out of space in my brain for storing all these things I am learning.

yes It does appear to be quite a flexible solution doesn't. Funnily enough I got the idea from another unrelated post about sacred geometry and expanding the metatron cube for laser engraving. weird how life works sometimes eh!

You were on the right track with Construction Snapping! It just works with Bezier handles.
Soooo, very simply 😃....

Get rid of that middle point.
Nudge (with the node tool) the straight line to get it to be a curved segment thus activating the handles you need (can be done other ways too).
Move them until the pink right angle symbols show up.
Now just move the handles in and out (shift will constrain the direction so you don't need to be careful) to get the curve shape you're after.

@JimmyJackperfect, thank you so much!!
