Topic: AutoCAD 3d wishlist

[MickD]

After the discussion about 3d Usage??, I thought it would be interesting to see what you would like to see in AutoCAD that would help you with your discipline to produce 'outgoing' drawings more effectively.
For instance, I'd like to be able to create a 2d drawing from a part in the model with ortho and section views. I know this can be done using paperspace and other tools but it can be a lengthy process.
Example, open a drawing, pick your object from a list and paste it in with selected views, annotate and start again, simple.

I know this can be done through customisation and I've been working on these issues for some time (and getting there ) but some things would be nice to have 'out of the box'.

What would you like?

I've wanted the ability to create 3D polylines complete with real arcs (not splined and and not one radius for all arcs either) for over a decade (primary use would be for routing). I've had to fake it by apprimating the arcs with vectors. I haven't heard whether 2007 can do this or not (my hopes are not high). A more robust version of solprof that's a native method (i.e. programable method) would be nice, layer colors / linetypes on a viewport by viewport basis, 3D solids et al that aren't encrypted (yes I know how to xor the acis codes) and are mutable via code ... yada.

I would have a lot of wishes and I know some are pretty much to be avalaible in Acad2007.

• But still, I think that Splines should be "breakable" and possibly manipulated afterward in term of Starting and Ending tangency graphically.
  
• A permanent X Y and/or Z filter would be nice too. It exists in many CAD systems, like TurboCAD, for example.

Bert' try setting the PELLIPSE variable to 1, this should draw your ellipses as polylines which might make things easier .

Don't laugh at my whishlist  :kewl:

For many many years I've wanted a way to edit the 'surftab1' & 'surftab2' mesh densities without having to delete and redraw the mesh eachtime.

I never did get around to coding a lisp solution for this one.

By the look of it, most of our 3D wishes may be answered in 2007

I have offten wished that I could control to vertex mapping and meshing of RULESURF.  If you make a ruled surface between two closed loops, like a rectangle and a circle, depending on how they were drawn, the surface can intersect itself.  Then you have to mess around with changing the order of the vertices in the polylines and such.

In my new wishlist for Acad 2007, I want to includ a new old feature.

I've been trying Acad 2007 and I find a pitty that it is not possible any more to move a solid by gripping it. Even if we press ENTER once.

I want my 2000-2006 functionnalities back !

With the way it is to edit the solids in 2k7 I'd think you'd just write your own routine and post it.

I wish the osnaps were a little more intuitive with solids ... but then I am only a casual solids user on my job, so I am sure there is something I am missing ...

[Tramber]

I would like the modeler.dll to be loaded since the beginning, wich becomes accurate with 2007 and its 3D working space.

?? such as?? What do you need besides endpoint, midpoint, center, etc.??

I occasionally need to get the intersection where the edge of 2 or more solids touch, not the intersection of the solid itself, but the intersection of the face of the solid.

The workaround I have found is to get the interference solid, and obtain the endpoint on one of the faces that is on the same plane.

Filters?

[Keith™]

I fail to see how a filter can obtain an arbitrary point along the face of a solid.

I have long given up mesh surfaces for solids but before solids were I had such problems with it

I set up arrays of polylines in blocks that I could substitute one for another till I had all the points needed then exploded the blocks and gathered the polylines in consecutive order and ran this

Code: [Select]

(DEFUN C:CN3 (/ A B C D E F G  cn cnt L1 L2 s1 s2) ;
               (PRINC "CRITS TO CONN...")
       (SETQ A (SSGET (list (cons 0 "*p*line*")))
             B (SSLENGTH A )
             s1(ssadd)
             s2(ssadd)
             cnt 0
             cn 0
             L2 b
        );SETQ
      (repeat b
             (SETQ B (1- B)
                   C  (SSNAME A B)
                   D  (entnext c)
                   E   (entget d)
                   F  (cdr (assoc 0 e))
                   cnt (max cn cnt)
                   cn 0
              )
            (while (/= f "SEQEND")
                  (setq g (CDR (ASSOC 10 e))
                        pt (trans g c 1)
                        d (entnext d)
                        e (entget d)
                        cn (1+ cn)
                        f (cdr (assoc 0 e))
                  )
           (IF (LISTP L1) (SETQ L1 (cons pt L1)) (SETQ L1 (list pt)));if
            );while
        );repeat
          (command "_3dmesh" l2 cnt (car l1))
       (FOREACH F (cdr L1) (COMMAND f)   )
       (command "_erase" a "")
    'DUN
);DEFUN

you have to make sure that all polylines have the same number of points (you can move two points to the same place) and a are the same direction, and have no more than 256 points or polylines as that is/was? the limit. I was able to make some pretty complex objects using this method.

The Fountain, stand, and Base are each made up of such meshes

For heavy and light weight polyline filter:

(SSGET (list (cons 0 "*p*line*")))

Code: [Select]

(SSGET (list (cons 0 "*POLYLINE")))

?

Well make up your mind either it is a combination of points as in

the intersection where the edge of 2 or more solids touch

or it's arbitrary.

Just trying to figure out what you mean.

Sorry Polylines only came in one flavor back then, you should decide which flavor to use and adjust the program as necessary.

[Keith™]

I suppose a picture would be worth 1000 words ...

The first one is a scenario which I find myself needing to accomplish regularly, particularly when dealing with multiple plane roof sections with multiple pitches.

The second one is my workaround to find the point. It would be nice if there were an implied intersection or a defacto intersection where the edges of the 2 planes cross, but alas there is not ... or rather I have not yet found it ... if you could give me a better solution then I would be tremendously thankful.

OOOhhhh .. those need resizing and I don't have the proper software at home .. I would be appreciative if someone could do that for me ...

[CADaver]

oh, I think I can see what you mean.  non-orthogonal intersecting surfaces.  We rarely run into those, so it didn't jump to mind.

[Keith™]

I am glad I am not going crazy .... I thought I was for a minute ...  I'm gonna delete those pictures now ...
