points disappear

[shamus]

Hi all,

using autocad 2004,
could anyone explain how points dissapear sometimes when i zoom in. I've tried to change the point format with no success.

Thanks in advance.

Dunno, just make sure PDMODE is still set to 3, and PDSIZE is set to something appropriate. If working in metres, set it to 3, if millimetres, set it to 3000.

P.S. Welcome to the forum.

Thanks Alan will try. Regards

If what Alan suggested doesn't work, post the drawing for us to look at.

Alan knows how to make a point, so hopefully it will work. :mrgreen:

Hi guys,

just to keep you up to date,
i tried playing around with PDMODE as Alan suggested and noticed that if i type PDMODE or click 'format', 'point style' which i guess is the same thing, the problem is resolved for a while. If it appears again i just PDMODE again. Its not the perfect solution, nor do i understand other than its a graphics thing, but it works for now.

Shamus, just a stab in the dark here, but are you running a lisp routine in between when it works and stops working?


Alan knows how to make a point,

Yeah, yeah, yeah. Very good AGM. :lol: :P

Thanks Alan,
Will look into that, i do have a few pieces of scripts one that hides and unhides objects. Also we had a demo of a new piece of software that runs within Autocad of which i am uncertain of the format of the script, ie VB etc, its protected. I will try to observe which events cause the problem when using the commands.

[Alan Cullen]

Keep an eye on it. Sometimes a lisp routine can change the value of PDMODE, but does not change it back again at the end of the routine.

If it is being caused by a protected routine, then you can set a button up to reset it very easily.

I dont think its changing the values of the point style but i notice that if i type pdmode and click ok, the points return. So if i assign '^C^Cpdmode' to a button such that i can reset the style, is there a way of having the button to also ok the command?

[Alan Cullen]

Have you just tried a regen to get the points back?

I don't follow what you mean by this, "is there a way of having the button to also ok the command?"

What value is the current setting when you type PDMODE to get the points back?

[shamus]

Tried a regen, didnt work.
pdmode set to 35.
I see the button as a click it once and it will run the command and then continue with autocad, such that you dont have to type the enter button, like i said its something and nothing.

[Alan Cullen]

What did you set PDMODE to last time you reset it?

Using a button is one way to reset it, another way is to add a shortcut to your acad.pgp file, e.g.

PD, *PDMODE

I would prefer the shortcut, as I prefer to use the keyboard.

I usually set PDMODE to 35, and PDSIZE to 0 (zero)
This seems to do the trick for me. I prefer to have PDSIZE set a value as a percentage relative to the screen size, rather than an absolute value previously described in this thread.

[shamus]

Hi guys,
thanks for your interest up to now,

Alan, I try to keep my pdmode set to 35 as this seems to be a good representation of a point to me. So its allways set to 35.
Will look at the acad.pgp file. I prefer the keyboard also.


NBC. have tried to use the units as a % and a size and still the problem would occur.

However by either typing pdmode and pressing the enter button or by pressing the point style and clicking ok, the points return.

Got to go offline for now so thanks for your help and will check back latter. Thanks again..... http://www.cadtutor.net/forum/images/icons/icon7.gif

Don't worry about me, Blue. I often look at PDMODE and for some reason think SIZE. I'm a dummy. :P

It is a strange problem though. I'm rapidly running out of ideas.
