Irricad

Irricad 15, and it is still happening.

all of a sudden if I use modify/select/window or lasso the objects appear for a second then disappear. I can modify objects one at a time but suddenly I cannot select groups of objects.

Did I turn off something accidentaly?

I am having the same problem. It is also happening to my AutoCAD. I tried the solution mentioned for the V12 (rename winini file) but that did not work

I am getting the following error:

OpenDWG was unable to open
<filename.dxf>
OpenDWG Error #287
Viewport entity with no extended data -- invalid

I saw the previous post on this topic and deleted the layout tab.
It is a version 2010 dxf file.

I get this error message when I import a dxf file. The contours look OK. What does this message mean?

I designed a zone of sprinklers with 20 psi as the design pressure, and Irricad designed the zone at 30 psi pressure. I did the same sprinklers on another project this week, and that didn't happen. I made a global change to 15 psi and the pressure that Irricad designed for was still 30 psi. Any idea...

I have laid out a design and I select design-zone design-velocity design and nothing happens. Is the file too large? Is there an upper limit for size?
