Is there a way to adjust anchor handles perfectly?

[Vladislav_Cherkasov0645]

Hi everyone! Is it possible in Adobe Illustrator to adjust the length of anchor handles without affecting their angle? Or vice versa — adjust the angle without changing the length?

Achieving this precision manually with a mouse feels impossible, yet it’s so necessary for small optical adjustments, fixing "optical kinks" in smooth curves and customizing fonts and making other detailed edits.

Right now, I rely on these clunky workarounds:

If the line is straight, I create a helper line and drag the handle along it. If the angle matters, I use a circle for control.

But honestly, this is so tedious, and I’m exhausted from doing it over and over. 

I’ve heard about path scribe, but I can’t afford them right now. My other searches have been fruitless.

Are there any hidden settings, shortcuts, or tricks for this in Illustrator?
If anyone has encountered this and found a solution, please share!

Vladislav,

I am unsure whether you use it already, but otherwise you can ease the pain with the Line Segment Tool by ClickDragging from the Handle into the Anchor Point, snapping to both; and you can easily move the line to the other side of the Anchor Point (ClickDrag by the Handle end to snap); and you can easily extend the length of it.

For angles, you can rotate the (Line Segment) line round the Anchor Point by a specific angle (select the line and Alt/OptionClick the the Anchor Point with the Rotate Tool) if applicable, otherwise your circle way is fine as it is.

Smart Guides are your friends.

Like Jacob said, smart guides and the methods he described are the solution with Illustrator's stock tool set. Otherwise Astute Graphics' plugins (Inkscribe, Pathscribe, etc) would provide considerably more options and more fine tune control. I subscribe to Astute Graphics' suite of plugins mainly to have access to Vector First Aid. It saves me so much time dealing with customer provided PDFs and other problematic vector art that it makes the plugin worth the money of the entire suite.
