I need a new linetype, but can't seem to create what I want.
Can I ask for help here?
this linetype will always be used as an arc.
it needs to have a dot with a space on each side.
It needs to have a dot and 2 spaces in the center whether it is 2' or 20'

can you help?
I would have thought to draw the arc, either two separate arcs or one and
some trim lines, and put a point in later. Set the point type to the dot, or
use a very short dash.
You could have the trim lines as a block for insertion from design center.
You could probably write a script to do this, or a macro? but that is beyond
Another possibility is to draw the arc, then change its length, method
depends on wether you have the line length button, which in turn depends on
which version of AutoCAD. But linetypes definately dont do this!
Man, I hate labor intensive, repetitious tasks.
This looks like it might be a nifty application for lsp. Can you give
more detail about the geometry? For example, is it always the same
angle, or is there anything repetitive about the nature of the art?
If we can define more specifically the nature of the repetition, then we
should be able to write a program.
YOU CAN ALWAYS ASK.
This is for mep plans. It is simply an arc from the switch to the light.
look in the folder labeled linetype.
on the left you see what we have now, on the right you see what the boss
The space dot space will be constant, the length of line on each side
Thanks for looking,
Have you considered using the linetype scale in the properties box?
1. Create the linetype
2. Draw an arc (I use the "start - end" one)
3. Select arc and click the "properties" icon
4. Change the linetype scale value until it looks correct.
Just my thoughts.
good thoughts. I had never set the LTS for an individual entity. how
you could use the linetype suggested, or create one so you had more
control over it's parameters, and run a lisp routine that calculates
what the LTS should be, and then modifies the arc.
seems more eloquent.
I'm going to bed. :)
But where do I find the properties box? The only way I found was command
line CHANGE PROPERTIES ltScale ..............
( see, told you I had never set the LTS for an individual entity. )
I think that I understand what you want. Presently, your drawing an
arc, probably a three-point arc. You want the arc length to the
constant regardless of the radius of the arc. You want a single space,
and a dot centered in the space.
I work in release 2000. If there is a more direct approach in a later
version I wouldn't know about it. You could define a line type that
would give you your desired look at a particular scale. For a
particular arc. I don't think that you can apply different line type
scales to selected arcs. If I am wrong about that, then you don't need
to read any further.
I can think of only one way to achieve the look you desire. You need
three entities. Too short arcs and a dot in the center. That is not
the line type approach, but would look the same on the paper.
THE HARD WAY. Keep all of this wiring in a single layer. You draw
without regard to how you want it to look in the end. Don't put
anything else in this wiring layer. Then, right before you plot, you
could run a lisp routine that would select every arc entity in your wire
layer and create from this the three desired entities that you want to see.
(setq it (entget (car (entsel))))
Create an arc segment and type that on the command line. Then check out
what shows on the screen. The DXF code shows. All that AutoCAD records
that we get to work with is the center of the circle, the radius, and
the angle to the endpoints. These points could be used as the first
endpoint of the first arc and the second endpoint of the second arc.
Then you could calculate the second in point of the first arc and the
first in point of the second arc. The entmake command could then be
used to create two arc segments. Similarly, calculate the point
location of the dot and create it.
The new segments created could be put in a layer of their own, which
does plot. Have the original wiring layer in a layer which does not
plot. The hassle factor will be editing. Lots of times when I'm wiring
I like to highlight the arc's grips and stretch it to where I want to
be. When you break it up into three entities, you lose that ease of
THE HARD WAY, PART TWO. Another approach would be to have some region
entities hide parts of the arc. Masking. In a similar manner to the
procedure first described. You could select all of the wiring in a
particularlayer and create said masking entities globally. With
basically the same information. It comes down to how you like to
organize your database.
Am I the only one who now believes I'm anal retentive?
( Hi Michael. Long time, no type. Been having hardware issues and
spending NO TIME on the boards. )
Am I missing something here? IE: What the boss wants? Why the hell would
someone need/want to reinvent a/the wheel for? Did the 'boss' just off the
tater wagon and land on his head or has he money to blow? I'm not sayin I've
never went off in search of a left handed monkey wrench
before.........but..........? Aw shucks, I read this one in Dilbert with the
pointy haired boss...........har har har, I got it! ;-)
