selection set filters |
|
|
I would like to create a selection set of Radial only dimensions. How do I
go about this. The return value for radial dimensions assoc 100 is (100 .
"AcDbEntity") not the (100 . "AcDbRadialDimension") association I require.
I've tried to cdr through the entity list by using a conditional loop (while
(/= (car entlist) (cons 100 "AcDbRadialDimension"))(progn (setq entlist (cdr
entlist)))) thinking that I could use ssadd here but the assoc (100 .
"AcDbRadialDimension") appears to not be equal to (cons 100
"AcDbRadialDimension") for some reason. Even if I use (cdr(car entlist)) it
does not equal "AcDbRadialDimension" and the condition is never satisfied.
Is there something I'm missing?

In your filter list, filter on the logical bitwise AND of code 70 for
4......the following will get ALL Radial Dimensions in the drawing:
(setq ss (ssget "x" '((0 . "DIMENSION")(-4 . "&")(70 . 4))))

are there similar functions for diametric and angular dimensions?

Yes, look into the DXF Reference Manual for the Dimension Entities. See what
the values are for the different type dimensions under the 70 group code.
From memory: 0 is Linear, 1 is Aligned, 2 is 'forget', 4 is Radial, 8 is
'forget' and 16 is 'forget'......hmmm only remember 50%, not good. Oh well,
that's why we have manuals ;-) ,but I don't have one available right now and
the wife wants to watch a movie......

OK, so my memory is horrible tonight......here's the description of the 70
Group code:
Dimension type.
Values 0-6 are integer values that represent the dimension type. Values 32,
64, and 128 are bit values, which are added to the integer values (value 32
is always set in R13 and later releases).
0 = Rotated, horizontal, or vertical; 1 = Aligned;
2 = Angular; 3 = Diameter; 4 = Radius;
5 = Angular 3 point; 6 = Ordinate;
32 = Indicates that the block reference (group code 2) is referenced by this
dimension only.
64 = Ordinate type. This is a bit value (bit 7) used only with integer value
6. If set, ordinate is X-type; if not set, ordinate is Y-type.
128 = This is a bit value (bit 8) added to the other group 70 values if the
dimension text has been positioned at a user-defined location rather than at
the default location
You will have to play around a bit to get the results you need, since I got
lucky with the radial in that it used an Integer that could have been a
bitwise number........will toy with this tomorrow if you haven't figured it
out yet.

Many thanks Jeff. you've been a great help. Where do you learn all this
stuff anyway? I've been studying this for hours without much luck. I've been
trying to teach myself autolisp, and so far, so good. One thing I have come
to discover though, is that the more you learn the more you realize you know
nothing. Thanks again.

You're welcome Chuck!
As far as learning, I just did what you are now doing.....lots of trial &
error....reading the help, newsgroups and forums....spending more spare time
on the computer than I care to admit.
I couldn't agree more on the "don't know nothin'" part. I am still
constantly learning from others' work.
Good Luck,
Jeff |
