Linetype Problem

Linetype problem

Via internet I received a drawing file from a fellow to which am having
problems with. The file has a few lines which show up OK and others to
which I cannot do anything with. The whole set of lines needs to be
connected as one big polyline, to which it can't.

I did a simple LIST on the lines and get these responces.

OK lines:
Angle in UCS XY plane: 90 degrees
Number of Vertices: 4
There are X values and Y values cited and Z is set at 0

Problem lines:
Properties: Open, Non-periodic, Non-Rational, Planar, Non-linear
Number of Knots: 12
Number of control points: 8
There are X values and Y values cited and Z is set at 0

Something about reading the Properties with the problem line wories me.

The first sounds like a polyline and the second... something else. Could
they be Multilines? I had them in one set of drawings from Acad, Icad could
not do anything with them. Not sure that has changed but Turbocad had no
trouble exploding or manipulating them.

Maybe he created in Turbocad?

Possibly, but they are equally native to Acad. Turbocad has a very good
range of file and entity types it understands.

You didn't read the LIST results very carefully. The first object is a
POLYLINE (possibly an LWPOLYLINE), not a "line."

The second object is a SPLINE, also not a "line."

Your problem isn't with "linetypes," but rather with attempting to join
non-joinable objects.

LINE and (LW)POLYLINE objects can be joined using the PEDIT command.
However, SPLINEs are a different type of object, and cannot be joined with
other objects. You may be able to convert the SPLINE objects to Polylines by
exporting them in DXB format and then re-inserting them. Whether this will
work for you depends on which version of which CAD program you're using.

You may have hit upon something. So many users think that the SPLINE
function is the same as FIT CURVE during PEDIT. I usually use the
latter, but the fellow sending may not have. Will send him a message
tonight.

As mentioned, the fellow sent me a file again. He altered the curved
linework from a SPLINE to the FIT CURVE option. Things fit, the lines
can now be combining into one long polyline also.

Going to have to put that down into my notes in back of manual.

What manual is that?

I received a little yellow manual with my installation box. Back pages
have title at top for notes also.

Ah, so long since I had a printed Icad manual that didn't occur to me. I
thought you might have been writing one for people supplying you drawings -
don't laugh, I have seen a few from government departments and mining
companies. They all contain some sort of personal, biased requirement. Like
the gov't won't accept Paperspace, but their layer colour requirements are
almost logical.

wadda yuh mean, won't accept paperspace?

I have been in land development for thirty years, and most every
drawing copied and sent out the front door was printed in paperspace.
It is infeasible to otherwise show a HUGE parcel of land and then all
the attendant grading, concrete, utilities, buildings, etc. for the
development.

Went to apply for a job at a local firm four years ago, and they gave a
test (on Autocad) as to setting up a plan page in paperspace, with
underlying work all rotated, and certain company standard features
Xref'd in.

One place I went to had all work done on layer zero. You could not have
any additional layers. To vary the line width it had to be a polyline
with a width. Colors could not be used for line thicknesses or line
types. This so they would be 100% interchangeable with other firms.

I know but hey I didn't write the spec., I have complained (so have many
others). Xclip is actually a good pspace replacement for me, but didn't
exist when I first came up against this "standard".

Funny what is a strict requirement of one office, is completely unacceptable
in another.

I have seen a handful like that, it would be hugely restricive. Sometimes I
wonder if particular office standards were born in an environment where
productivity was not a major concern, or the work was not all that
complicated.

Most likely explaination is that the person (or committee)
setting the standards had no knowledge of CAD or even drafting.

Oh they always have some knowledge, but often restrictive standards are born
of distrust or inter-operability requirements. I think it's funny that
"proper" qualifications for a drafter here are quite high - often after they
qualify they are employed as "diploma engineers". Whereas basic cad drafting
standards often don't even trust or allow the draftsman to get the best from
the software.

Well, we are getting a little bit off subject here, but about 15 years
ago at one firm I was with, they had Us Engineering types calculate and
do the linework to be accurate. Then, run a blueprint and red-line in
the applicable notes. The job then got handed over to some graphic
artist type person, and they then slapped on the notes. Even the itty
bitty ones, the ones with arrows, the long list of huge paragraphs of
standard notes. All of it.

I think it was because the graphic software at the time had spell
checking, unlike any CAD software did.

Hey it's not likely to cause confusion with other threads! Is that by way of
example of productive use of software? Were the notes added to the cad files
as "objects"?... our gov't contracts dept won't wear that either - this in a
small way reflects the subtle ways in which Australian authorities stifle
inventiveness (because they have none of their own)... then go and buy
technology offshore because they are smarter. (personal grumble)
