Plan readability degree setting for linetype rotation

[CCarleton]

For upright linetype definitions is there a way to define what degree of rotation the linetype will rotate the text on? By default it's 90 degrees, and ideally I'd like to set it to something like 100. Issue becomes you cannot reverse upright text so in some situations all the text that runs generally north/south may not all be orientated the same direction. I'm trying to avoid having to continue using draw specific linetypes because I absolutely loathe drawing a bunch of linework the "wrong" way and having to QAQC all lines drawn to see which need to be reversed.

Thanks for any and all help

If you are talking about complex line type definitions, like the GAS_LINE line type that ships in acad.lin, then the line definition is created from left to right, i.e. "stroke, G, A, S, stroke". This is not reversible. Thus, the direction of the text in a line depends on the start point and end point. To "reverse" the text or change it's orientation, you have to flip the line's start point and end point. There are lisp's around that do that for you. The best way to fix it though is to create an office standard where you don't draw lines the wrong way.

HI don't need a lisp command reverse flip the line direction

Yeah, let's see if I can describe this better.

We have our own linetypes. There's a big debate about whether upright linetypes, the ones that will always read upright regardless of how you draw them, or ones that show display the linetype feature based on draw direction should be used. I dislike draw specific linetypes unless they are inherently necessary such as using a carrot symbol, ">", to show flow direction as you obviously need that flexibility. When it comes to any text based linetype no one wants to read the word GAS upside down when you print it. Thus upright linetypes are handy because you never have to worry about drawing it in a way where all lines have to be reviewed in a drawing and reversed as necessary (like Remi mentioned).

The PROBLEM that some people dislike is that if you use an upright linetype definition you lose all flexibility so as shown below we have a storm linetype that is an upright definition, and then a gas line with a road name. The gas and road name are rotated one direction and the storm is rotated another. The storm rotates this way because it's beyond 90 degrees and the way CAD is rotating it keeps the text upright, but now you have text that reads two different ways and one would have to tilt their head either direction. You either have to deal with it, replace the linetype with a draw specific one, or rotate the gas and road name.

I think my request is basically a CAD wish because I don't think it exists. What I was hoping to be able to do is have some sort of variable to control what degree of rotation CAD will define as upright or plan readability. It exists in C3D labels where you can define the degree of rotation for how it will label something and at what point it will flip the text. I would love it if I was able to define something like 95 degrees as the upright point so that when things are SLIGHTLY skewed we could keep the storm line rotated the same way as the gas and road names because this is basically the only qualm people are having with upright linetypes. Without it we're forced to continue using draw specific linetypes and that means scrutinizing every text based linetype we have, which can be cumbersome in bigger projects.

You can define your own line types that have the text fixed at an absolute angle relative to the coordinate system. See the customization guide for line types.

The rotation angle of the characters to be displayed in the linetype. The rotation angle must be prefixed with U=, R=, or A=.

U= specifies upright or easy-to-read text.
R= specifies relative or tangential rotation with respect to the line.
A= specifies absolute rotation of the text with respect to the origin; that is, all text has the same rotation regardless of its position relative to the line.
