I have version 11 of cmsintellicad and now I upgraded to version 13, and when I use the extend command I have to select line by line I can't make a window over multiple lines. I'm working in 2D, another situation I notice is that the orthophotos in png format that I put in cad when I zoom in they constantly blink and in the past I didn't do that.

In previous versions of CMS IntelliCAD, you might have been able to use a window or crossing selection when using the Extend command, allowing you to select multiple lines at once. If this is no longer working in version 13, it's possible that the selection settings or command settings have changed.

Ensure that the Extend command is set to allow a window or crossing selection. You can try setting the Selection mode in IntelliCAD to make sure you're not restricted to selecting one line at a time. You might want to reset the selection options or use the SELECTION command to check or modify the settings.

Hope this help.

Since you were just asking about GoAutodial V4 installation, I think you might mean how to extend the disk/partition after installing, right?
