snapping accuracy

[David Ramey]

I think DataCAD ought to have snapping accuracy only limited by the device. Right now we have double precision math internally. Well we don’t externally like here is an easy one; sometimes, practically all of the time I set more than one snap option at the same time, Why is priority given to perpendicular over mid point, and so on. We want to be able to set that. Our screen should snap perfect and have every imaginable adjustment to do so.

With 14 having issues with every day I might buy some hard locks for 13 and it’s only a little better than 12 was. BTW I wonder if DataCAD 14 takes full advantage of 64bit machines now? Has the string line dimensioning thing been fixed in 14? I mean what does it really do that 13 don’t? Is it worth it yet? That’s what everyone wants to know.

Uhhhhh,

 

I have no problems with v14, including object snapping. The little issue of Perp at Arcs was addressed immediately.

 

I've not experienced any issues at all with String Dimensioning, and I use that frequently.

 

I love v14. I use it at work here at TDA. I use it at home at Toad Hollow.

I have one with perp. and midpoint being on at the same time and the program giving precedence to perp. I would like to be able to hot toggle through the differing snaps. Anyhow DG said that the stringline issue had been fixed a long time ago. So maybe I was getting old messages off of the mail server. I still don’t know how to set snapping precedence though. Even if I only set endpoint DataCAD has and probably always will snap bad (in space real close to the line but not exactly there) as do all other programs in their own way but we need a toggle, so that when you are over a spot where two snapping conditions that you have set exist, then you can quickly toggle to the one you want AutoCAD and SU both do this along with many other CAD programs.

I wanted to keep the square too. That circular pick box sounds better, but it ain’t. Why not just add that on as a feature that can be changed from square to circle? Same with the snapping (F1 to toggle between any snapping condition that exists within the pick box). Quadrant snapping doesn’t seem quite right as I have drawn many circles but their quadrant is never where a quadrant should be at 90,0,270,360 degrees. Being able to pick a command quick is cool but not being able to snap just how you want in even one place can cost you time.

So far though, with architectural things, DataCAD seems best for the money though the only thing that we would want from 14 I can think of is that knockout feature if it works at least on associative hatching. See if that will work on a ellipse too. All I know is the math on DataCAD still seems to be from the 80’s. They do things like set the number of polygons instead of limited by memory. It does the job here, I guess, 13, and that’s all that matters.

[David Ramey]

Handy feature no doubt about it. I didn't know it did that but it's probably on your web site somewhere. Anyhow that is why we would want it. For that feature alone it would be worth it to me.

Unfortunately, I don't get to make the final call on that. We are starting to gain a lot of people that want to buy, have good credit, and money down, yet people are still having problems getting thing like construction loans. I have one with a foundation in and waiting for his loan even though he probably only needs 50% or so, the banks are giving him static.

Anybody know anything about this? Anything would be a thanks in advance.

Well what bothers me most are having 2 snap conditions in the same pick box and having to zoom in every time to get an accurate snap. I wish there was a toggle for that. Way back in UdderCAD 14, it did that and instead of writing the snap condition it used symbols. SU uses symbols too. If there is not some kind of software patent on this, I think DataCAD ought to do this instead of literally spelling out midpoint or perpendicular. Use a symbol. It covers up less stuff that way.

But the snap issues are still there on the screen especially if you have your drawing away from 0,0. With double precision this shouldn’t happen unless you are as far as the moon is from 0,0 with 0,0 being earth. My guess is they had to cut a few math corners to get those old single precision files into double precision. I’ve occasionally had stuff snap virtually with it turned off. When you zoom in, the snap would be off by 1/32” or so. Whether zoomed in or out, the snapping should maintain the same accuracy. Other programs have issues too.

As far as what you say about having to type in commands in AutoCrap, I believe they have a tool bar that you pick what you want to do and then you put your pickbox over where you want to snap and then you can toggle through the different conditions circa 1998. OTOH plain Jane AutoCAD would never insert doors and windows like DataCAD does nor does it have all of the trim features nor is eve Architectural Desktop any faster that does insert windows because of the depth that the menus are buried.

I like that $299 plan and forget it once a year. Doing that monthly with a soft lock might help DataCAD too. We shall see how this upcoming year is going to go. If not better than last, then they may need me very little. That would be worse than how things are now.

Really all a CAD file is, is a database. The few snapping problems I have since DataCAD went from single precision to double precision was a great help especially when importing survey data. It’s just that there seems to be a limitation on the screen but none when you import coordinates. Those may end up real far from 0,0 and I like to leave them in their proper place. Entirely too much zooming in a case like that or you have to move your coordinates which sorta defeats the purpose of a coordinate system.

Maybe DataCAD could have a surveying add on package since it goes with drawing plans.

Here's my (undoubtably not unique) cheap trick to get this right 90% of
the time - even zoomed way, way out:

Assuming you know which of the various snap points markers is right,
simply nudge the cursor to a position where that point is closer than
the others. Generally the nudge needs to be away from the point you
want, which seems intuitively wrong. But it works!

[James Horecka]

Another way to force a snap to not get Perp but something else (like midpoint or quadrant) is to first click somewhere that would not have any chance of being perceived as being a starter point for Perp on the desired entity when you actually go to o-snap.

 

Does that sound weird? It's not.

 

Let's say we want to o-snap to 3 o'clock on a circle.

 

Well, if the last place you left-clicked or center-clicked was in a spot that might trigger Perp o-snap at, say, 4:00 on the circle, you may get that result instead of 3:00 (quadrant). But if your previous L-Clk or C-Clk was in a spot that has little or no chance of being used in Perp, well, you'll get that 3:00 Quadrant just fine.

 

You with me?

 

Please keep in mind, too, that you can simply turn ON Dynamic Snapping "Indicators" and "Hints."

 

Personally, I do NOT have these on, as I do not need them. I get the o-snaps that I want, no problem. No need for Indicators or Hints.
