DesignCAD User Forum

This subject has been discussed a lot, and acknowledged by developers but some say it does not affect them at all.  Apparently it is very difficult to fix.

To test you should start a new blank 3D drawing, in any recent version of DCAD max.

Draw a simple cube, or any other simple object, and turn on shading using the OpenGL mode (quick or gouraud), so the object remains shaded while you are drawing.  This mode is very useful for editing objects visually, because you see the shaded effects of what you just did.

Then try to draw a multi-segmented line by setting points with your mouse (not by point-relative command) just by clicking.  Try to place at least 6 points for the line.

Then try drawing a tube or a torus.   These involve numerous rubber-band lines.  For some it is almost impossible to set these points by mouse.

Then, whichever way this works out, please let us know your computer specs and video hardware, maybe we can find out what systems have the problem and which dont, or better yet something we can change to fix it.

I voted under the totally unuseable which is true on all three of my computers two laptops and a desktop

Rob,

I have reported this elsewhere, but I'll repeat it here so we will have information from everyone in one place.

I use two machines. On both all I see is very brief flickering of the rubberbands in OpenGL Quick or Gouraud shading. The redraws are very fast and do not interfere with drawing. I voted "no problem."

OK Rob, I followed your instructions & also vote for 'Unusable'.
Even without attempting to draw a tube my multipoint line was flickering on the first 10 points, 'laggy' on the next 10 and almost unusable by the time I reached 25 points.
This is consistent with my experience in all the years I've been doing 3D work on DCad, not new to recent versions or my current machine.

Adrian, please vote again, there is still only one vote under unuseable that being me!!!

Hi Rob,
So now I guess I'm being thick, but how exactly do I vote?
I can't find any links or references to a poll anywhere...

At the top of the first post in this thread you should see a poll with 4 questions, you just check the bottom one as applicable 

Well, maybe I  should, but I don't.
Am I looking in the wrong place?

Should look like this - are you using a theme other than the default?

I don't see any other settings which would affect it.....

This gets weird.
If I log out the voting option appears, when I log in it disappears again.
I did notice on the members list that I'm now listed as a 'Beta Tester', not a regular member. I don't know when that happened (or how) but it never used to be like that.
For the record, I've never beta-tested any versions...
I don't see any way for me to change that setting, I think I need whoever manages the forum to fix it?
Who is that these days?


Adrian
