Hello,

as I tried to draw some polygones using the commandbar (input as string "_PLINE x,y x,y ... x,y s _PLINE..." and so on) i noticed, that ProgeCADs command bar only accepted 9721 characters as input and stoped there, cutting the rest of the string.
Furthermore ProgeCAD needed very long for the drawing task (around 4 Sec without hardware acceleration, around 10 with, at 9721 characters) in comparison to AutoCAD where the drawing happend semmingly instantanious (for the complete string) although it was cut to single lines with:
" _pline
x,y
x,y
...
x,y
end
_pline
..."
which seems not possible for ProgeCAD. (Thats why the string was written to one line and how I discovered the boundary of the command bar)

My Questions are:
Is it possible to enlarge/modifiy the capacity for characters in th command bar?
And why is drawing without hardwareacceleration so much faster?

Thanks
Zerow

Hi Zerow,


We had a chat about this. There are several things which you can try.

For the command line input limit, none of us could understand the advantage of doing this like you are trying to do it. It would be far quicker (and more reliable) to save your extensive pline to a script or even use an autoLISP program to read points, similar to this one.

About graphics performance, you didn't actually tell us what kind of graphics configuration you are trying to use with progeCAD, as this well and truly depends on your own configuration and the kind of graphics acceleration that the user has. We demonstrated this some time ago with a benchmark that we did ourselves, here. The first thing to note is that progeCAD currently only supports OpenGL-based graphics acceleration. It does not currently support DirectX, so if you enable hardware acceleration on a DirectX AMD-ATI configuration and experience low performance for example, you have misunderstood the requirement. Also, if you are using very old hardware/drivers - or - even still using an unsupported operating system like Windows XP, you have misunderstood the requirement. These would be situations where software rendering could perform much better compared to an unsupported hardware rendering configuration. This is why we offer both options.

Also please read the updated article that we recently published about graphics acceleration for CAD, here. Note several key points, such as driver updates and system configuration. These are points that work for most users in most cases, but we cannot always troubleshoot specific situations involving third party products like video cards.

Please give these things a try and let us know your result.
