 Posted: Wed Jun 23, 2004 8:27 am Post subject: Simple Suggestion for Speeding Up Drawing Navigation |
    |

This is so simple, I'm surprised it hasn't been brought up before (or maybe it has and I just don't read enough).
Much of the problem with slow redraws in PowerCADD 6 has to do with the fact that it impedes navigation through your drawing. In other words, when you zoom or pan you have to wait for the redraws. Normally this isn't too much of an issue until you start navigating large and detailed drawings. In that case, you realize that you're waiting for the entire redraw to finish before you can zoom in another level, or pan another "step." That got me thinking, if command-period can stop a redraw, can't the zoom command incorporate that redraw interrupt? That way, when you hit your command for zoom in now (in my case it's command-2), it will zoom, start to redraw, then if you hit command-2 again before the redraw is finished, it will stop the redraw and zoom in another step.
This would significantly speed up navigating the drawing. If we could assign multiple commands to a single keystroke (a feature I know has been requested for PowerCADD 7, and which I heartily endorse) this could be done by simply stringing together command-period and zoom in now to a single keystroke. I suppose that would mean command-period needs to be turned into a "real" command that could be assigned its own unique keystroke, which I don't think it is now.
Either way, this should be very easy to implement for zooming. I'm not quite sure how it would work for panning though, if it could work at all. |

Perhaps one way to speed up navigation and screen redraws in PowerCADD 6 is the quality of the drawing during the zooming process. (Im sure this must have been touched on before).
I'll explain, if you look at Autocad or Archicad when you zoom out and in, the doors go all blocky instead of circular, the walls lose their hatches etc, it certainly speeds up the screen redraw and therefore navigation.
Perhaps there is a simple explanation for this

| That's a good idea. While I don't like the blocky appearance of round objects in AutoCAD, and having to manually regen in order to fix it, that does bring up an added way to improve the feel of PowerCADD. This would probably be a good solution to poor panning performance. If hatches, fills, text, and dimensions (anything else?) turned off when you started panning, and didn't come back until after the pan tool was released, it would help a lot. This would work with mouse zooming too, although it might be hard to implement with the "normal" zoom commands. This function would probably require a user preference to turn on and off, called "Quick Zoom/Pan" perhaps? Maybe you'd also want the ability to set the delay time for these objects to reappear, since it would depend on the speed of your computer. |

I agree. And more : it's so slow to redraw photos and pict objects : I would like a possibility to have only a single grey rectangle instead of the picture, like (I think) in InDesign.
And a single key to stop redraw of the whole drawing |
