If you have a team, please try to get colleagues who have the same problems to vote for these. UV feedback helps a lot, and votes do count.
That’s as much I can help though. And thank you for not being silent!

Yes, I don't know why i recorded the screen and when I switched from Rhino to Ai it didn't work.

1 - all correct.

2 - yes, i voted

3 - the reason is that it doesn't actually make sense to dimension the void, so I've never tried. But if it is necessary to avoid snapping problems, it can be useful

4 - correct. Solve this problem will be very important for me and for my team.

thank you for all

attached to the message you have a short video, where i'm comparing rhino and AI.

1 - yes, CADtools have too much different kind of dimension. As I said previously, the fundamentals are 5-6 maximum. the really important function of CADTOOLS is the serial multiple dimension. that is really effective. furthermore, both CADtools and Rhino, when you change the size of an object. automatically change his dimensions.
2 - i think AI team never have to dimension a drawing, sorry. We use radius and diameter dimension for different kind of information. Simple ex: radious for a vertex of an object and diameter for a *****. I know thad d=2r, but when you make object, you need two kind f different data.
For orthogonal dimensions: yes, shift could be an important and appreciate improvement.
3. yes is true, i never try it before
4. I don't understand very well this point. But...Rhino could snap a dimension to a previous one in some point (ex: vertex of the arrow, final and middle point of the extension line, center of the text of the dimension, maybe more). The most important point is that Rhino (better also than CADtools) have a
has a hierarchy for snaps. the first thing it looks for is the object, because obviously it is the object that must be quoted. So if it has a vertex and the end point of a dimension nearby, it always snap the vertex. Also if the dimension layer is on top. this is really important.

thank you

Hm. Can you please make a short video or a GIF (I use free and simple LICEcap for this, www.cockos.com/licecap/)?
I try to follow the steps you provide and fail to snap to a wrong point. I get the idea, but just can’t make it happen.

Regarding Rhino:
1. Well, Ai now has a lot of option to style these too. Not as much as CADtools offer, but Ai doesn’t aim to replicate it in full. If you have specific styling requests — please upvote an existing request (there is at least onc) or create a new one. One request per entry would help the team to evaluate the demand.
2. Ai team decided to minimize the amount of tools. The idea is that there is no big difference between orthogonal and parallel dimensions, and between radius and diameter one. You toggle these directly while drawing these. Instead of external modes, Ai uses internal modes. Speaking of the way to force the orthogonal mode — would you like to have Shift do that?
3. Ai also allow to draw a dimension in a void... click, move, click, move, click. How does it not solve the case you are having? Please demonstrate.
4. The idea of excluding dimension from Smart Guides is not new. But imagine you want to crate a dimension in a way so that the dimension line snaps an existing dimension line you already created? Since Ai’s dimensions does not have a way to specify the distance between the object and the dimension line in a stepped way (something CADtools can do!), the team decided to leave a way to achieve it... How does Rhino solve this?

Hi Egor, thanks for your reply. Yes, I mean 'dimension', sorry for my bad english.
- happy for disable units
- for snaps, no, it doesn't work very well. Try to draw a square and have his maximum dimension, starting from the same point. Of course, AI generate first dimension in a top layer, then, if the drawing doesn't have much zoom, AI automatically searches for the next dimension the final point of the previuous one ( because it's in the highest layer, i think). But AI ​​itself doesn't allow you to snap to a dimension! :) it's a mistake. to snap the point that i want i have to zoom a lot.
- for orthogonal dimension, yes, I know, but it's too complicate. please think about of a drawing full of strokes, lines, objects, texts. It is not possible to hold the guide perfectly to have an orthogonal dimension. Also, I must have the extension line of the dimension near the point I snap.

- regarding rhino:
1 - you have a lot of options for costumize your quote.
2 - basically you have 5 principal sub tools: orthogonal dimension, aligned dimension, radius dimension, diameter dimension, angle dimension. First you choose the type of data you want, than you can quote without problem.
3 - you can quote everything, also the empty space also some elements of the other dimensions.
4 - if you try to snap the same point, it prefer to snap to a line/vertex (to an object) instead of an other dimension...because it's not smart quote a dimension (but, as I say previously, you could do that)

Emilio, some time before Ai had none (I suppose by 'quote' you mean 'dimension'?)
Having one is something :)

The latest Beta build now allows to disable units — soon it will get released into a normal build.
As far as I know, it snaps pretty fine, but you say it doesn’t? Can you please elaborate?
The same goes about snapping several dimensions to a single point — have no problems with that.
It is possible to create orthogonal dimensions as well — you just have to move your mouse to the side for it to switch from parallel to orthogonal.
As for the CADtools — their site says version 14.1.2 is compatible with Illustrator 2024, but you say it doesn’t work? Or do you use the previous version and never upgraded? Either way, Ai is hardly involved. If there is another reason and it just stopped working for you — write them. No need to yell.

If you like the Rhino’s tool, perhaps you should explain what makes it superior compared to Ai’s one.
Please reply.
