AECC_contours again

[TCEBob]

On Feb 25 I asked for a way to change AECC-contour elevations. The answer proposed was to use vlax-get-property. Made sense, so I finally got around to trying it today. It seems that (vlax-ename->vla-object . . .) will not recognize the AECC-contours. Is there some supplemental info that I need to incorporate into vla to recognize them? Or where is there a detailed description of the object?

I remember.
Yes it will, or should I say "should?" What does your _VERNUM command report? Though it shouldn't make any difference, maybe you should try the alternative syntaxes... (vla-get-elevation object) or (vlax-get object 'Elevation)

 

[TCEBob]

Oh oh. Vla-get-elevation won't work on command objects like lines and arcs. vlax-property-available-p tells me so. Guess I have to go back to attributes for them.

Of course, Change works, but then I don't get the education.

Ecch. "common objects."

Hey... remember learning to ride a bike? Skinning your knees was part of the process. You also gained humility. Sheesh, now you're making me think of today's stifling methods... overregulation, overimposed assistance leading to overexpected assistance, overorganized recreation, leash laws, go-cart laws, bicycle helmets, blah blah blah. What happened to the days of losing a few fingers, teeth, or hours of sleep, long division, deriving your own formulas, for the sake of experience? So what if you didn't know that pure sodium thrown into water would create an explosion? The neighbors probably wanted a new pool anyway, right? And you'll never forget it 'cause you did it yourself.

Don't mind me. I'm just trying to soften you up a little. :]

Thank you, sensei. I take great pride in my humility.

Haven't blown up a pool with sodium, though it sounds
splendid. However, in 1943, in Texas, where Christmas was celebrated with fireworks, one could buy a "depth charge." this was a firecracker about 1 1/2" long and 1/2" in diameter with a wick sticking out of its side. It would float wick-up. We kids did not have a pool, pond or puddle, but we had my mother's oval dishpan and a hose. Gratification was imminent. I had the honor as it was my dishpan. Clearing my mind of all but the task at hand, I struck a match, lit the fuse, launched the depth charge into the placid waters and rejoined the troops. The universe was still for a few moments and then, kabam! A most gratifying eruption of water and a generous report. We rushed up to look for flotsam and saw that a 3" hole was blown out of the side of the dishpan. My pals hastily remembered appointments elsewhere and disappeared. When mom came home I 'fessed up, realizing that no alternative tale existed to explain the ragged hole in the dishpan. She was a feisty woman and I expected the worst, but perhaps she was more amused than angry because I survived with a lecture.
