Plot style or no Plot stlyle

I have been using Plot styles (.ctb) for years and I am very happy with the results. We basically have colortables defined to show different lineweights as we only do black and white plotting.  But a newby in the company wants to do all the plotting without a .ctb and assign lineweights to the entities itself. I know .ctb is the way to go as it gives the user more control but I am having hard time stating more benefits of .ctb over lineweights. Please comment. Thanks

It's all up to the drafter and what he wants to see on the screen as he drafts. The end product is the same. If you are using CTB, the lineweights only matter if is a Polyline. If it's a line or polyline (global width of zero) then the CTB will sign the width when plotting.

 

If one wants to be able to pick any color while draft and give it a lineweight then using the STB would be the way to go. Again, it's merely preference. But if you are going for company standards, you need to make sure that the CTB plot styles are consistent with the STB plot style lineweights that you assign each layer.

 

Make sense?

Well line wieghts can be assigned to lines as well. Its not Global Width, its the Lineweight (which can be set for a layer under Layer properties too). I did find one major benefit of .ctb- if we print a same drawing on 11x17 and A1- if we have line weights turned on, a line may look like a BLOB on 11 x 17. Whereas I can have different color tables defined for 11 x 17 and A1

There are many posts about STB and CTB already here that will take weeks to read. The conclusion is: It's like religion, hardly anyone would like to convert, both are always right.

The boss is the one who will decide, take him to lunch, may be your CTB will be the one he liked.

I will stick my oar in on this one, I personally prefer that the lineweight to be in the drawing, but I am very comfortable with it being in the CTB.

 

The reason I prefer it to be in the drawing is that it can be a little more flexible with 2 objects with the same layer and colour being able to have 2 different LWTs also I find if I send other people a DWG file then there is less missed out if they don't use my CTB.

 

What I think is very poor if an office uses both methods, things then get very mixed up. If a drawing with LWTs in it, is printed using a CTB with LWTS in it then the CTB will take prority, this can definetly cause confusion and potentially even mistakes. Consistancy is always the key. I have even worked somewhere that had CTBs stored in the default location (local) with each drawing using the default name acad.ctb BUT each user edited that as required. Hence the same drawing printed out by different users looked different. A complete mess

 

If you move to plotting in colour there is also the possibility of not use a plotstyle at all, this in my mind is even better since all the plotting characteristics are built into the drawing.

The CTB is the easiest to recognize and manipulate.

One can associate the color of the object to a lineweight.

 

Another method assigns a layer to a specific lineweight regardless of the color of the object on that layer.

 

Still yet, one can assign a thickness to an object which would be like a real-time lineweight display on the monitor.

Again, the color of the object becomes redundant.

 

Looking at these three options, which would be the least confusing?

Personally I have allways prefered to assign line weights by layer. Allocating lineweights by colour just seems to limiting to me. Very, very occasionally I will tweak the lineweight of one entity directly. Just because I can :smileywink:

You can argue that they will have to convert all the existing detail library if they want to switch from CTB to object lineweight and see if the guy offers his time to do that then.  The familiarity of users with the association between the color on the screen and the designated lineweight is another plus point of CTB, as Scot-65 has pointed out.
