For a vector based software, I think Illustrator's snapping features should be improved like AutoCAD implementation. I can't see why this is impossible.

Since you are here, please also vote for this related request about the ability to actually add points at tangents:

Meanwhile there is a plugin that allow to create tangent points with ease, PathScribe/InkScribe by AstuteGraphics.
It does not mean Ai should not have these by default, of course.

Also, please vote for this related request, which is about having snaps to tangent points:

Seriously. I can't believe this is not yet in Illustrator after 20 years. Basic AutoCAD like snapping is a necessity.

Besides this, you also need to be able to snap to a line extension BEFORE you drag a line out, for example to plot a new point with the pen tool that is co-linear with an existing line. I can't say how many times (probably in the tens of thousands) in my career when I have had to drag out a construction line extension just so i can start a new line that is co-linear, or at least starts co-linear with an existing line, and then delete the construction line when i am done.

I agree, and asked the same thing thing to be added as options in smart guides from Glyphs (revealed in the last Beta version available.

Please add tangents. It's ridiculous this is not implemented in 2019.

Yes please. Why is this not a boiler plate feature of a program that has been around for 20 years +????

Adobe, you need to look at professional CAD software in general. Illustrator ***still*** lacks some fundamental line-based drawing tools, like vector trim, offset, tangent detection, and so many more.

I'd like to request a Smart Guide when drawing lines for when you are over a curve and the line is tangent to a curve.

For Example:

Draw a circle by plotting 2 points + defining radius
Draw a circle by plotting 3 points

More object snapping options:
Snap to tangent
Snap to parallel
Snap to Perpendicular
Options to turn various snaps on/off

You really should improve and snap and alignments. Really disappointing for a geometric vector design program. Consider that other software like Corel Draw, Affinity Design, the good old freehand this thing works much better, even free software Inkscape works better.

Beyond "align to point" you should also make align, and intercept alone the curvature of the vectors, as "hook to object" of freehand. If external plug-ins like those of the Institute or other external scripts are able to implement these functions, to the great I would say, I wonder why mom never ADOBE can not? Do not you want to do it? can not do it? where is the problem? or does not want to rage against Astute??
it is shameful for a software leader in the field as Illustrator that boasts 30 years, in my opinion NOT honored service that pity of many gaps like this and also slowdowns and a lot of machines in working. Freehand was very, very, very, very, very, very, very, very, very, very well.

The ability to easily create tangents would be extremely handy for many designers out there. AutoCAD has an extremely versatile and intuitive system for them, it would be wonderful to finally have a tool for this. I PROMISE you, designers will respond well to this.
