Geometrically Significant Path, Shape Creation


Recommended Posts

I'd like to see tools that leverage geometric measurements to make shape making easy.  Specifically:

  • Path tangent to 1 curve
  • Ditto 2 curves
  • Arc tangent to 1 curve
  • Ditto 2 curves
  • Ditto 3 curves
  • Circle tangent to 1 curve
  • Ditto 2 curves
  • Ditto 3 curves
  • Path perpendicular to 1 path
  • Ditto 2 paths
  • Path along shortest distance between paths
  • Arc by three points
  • Arc by start-end-direction
  • Circle by three points
  • Circle by two points and direction
  • Shape exactly inscribed in another shape

Some of these will be looked at when we have time.  Might need some examples of what you mean for some of these cases.

I'm back.  Not only out of the office, but had no internet access all weekend too.

 

Could you give diagrams of the following, just so I am clear on each. Then I can see what stuff might be achievable through snapping, and what requires new object types.  Thanks.

Sorry it took a while to get these posted. But here are examples of what I’m talking about. Some of these aren’t super obvious, but where curves touch in these examples, they touch at one point and only one point exactly.

 

I threw in a couple extra I thought of as I was doing these, too, including something that will make long shadow aficionados like me swoon.

 

HTH!

Another example if things that could be added through scripting ;)

 

Not sure how scripting will help with some of these examples...

I can see some of these examples being achieved through snapping.  In fact, we already have some back end support for finding a tangent and perpendicular at a point on a curve, and using it in construction snapping, but it needs refinement before we make it public.  So, anything that works on a tangent or perpendicular from one curve should be possible.

 

The other examples are quite involved. We may look at them the future.

Oh yes pretty pretty please, I miss these features a lot.

 

I worked with them in Illustrator almost everyday via the Astute Graphics plugin »SubScribe«.

To be honest almost all there plugins were really great during the trial period – but after that they come with a price tag.
 
I'd really love to see especially something like the »line tangent to two paths« and »line perpendicular to two paths« option – these would help a lot.
 
The ColliderScribe plugin is also preeetty nice … sorry for raving so much about it, but their plugins or – more specifically the function they provide – really are that awesome. :,D

I have Astute Graphics plug-ins as well and they make Illustrator much easier to work with. One of the impressive things about Designer is that they have included some of the VectorScribe features natively.

 
Yeah, you're totally right – I forgot to mention it, thanks for pointing out! 
The »white arrow« indeed already has a very VectorScribe like feeling.

 

I probably got used to it, I didn't even notice.
 
Edit: Of course the shapes and the corner tool! Oh my … yes, the corner tool made my decision to purchase Designer in the first place, haha.

That'd be ideal … I'm still fiddling around and figuring stuff.

Right know I'm all about – yes I'm a bit late in the game, don't hit me please – long shadow icons and stuff.

 

Really could use that tangent/perpendicular feature therefore, especially for non-geometrical rounded shapes.

But yeah, it'd be nice in generell, not only for that purpose.
