and I need add more Ram to my virtual machine. This mv it is a windows 7 and I only can use this amount ram dedicate to this vm: http://imgur.com/a/bwz9Q
Your picture shows the display settings, with virtual VRAM. If it's normal motherboard RAM you want to change then look in the "System" settings, motherboard tab.
And remember that RAM can't be simulated: you can't give RAM to the VM that your host doesn't have or is already using.
I need configure the virtual machine with more ram because I can't render the image on the software proteus (https://www.labcenter.com/). I use this software to build schematic and board electronics. At the moment I execute view 3D the virtual machine with OS Windows 7 don't display the image. I am thinking this occur because the memory image which host dedicate to virtual machine it is insufficient!
I very much doubt that your problem is caused by lack of display RAM. What makes you believe that?
By the way, I think it's about time we had a VM log from you - this should be automatic when asking about a VM problem. With the VM fully shut down, right click it in GUI. Select "Show Log" and save "VBox.log" (ONLY) to a zip file. Attach the zip here.

Also I have doubt about this but I think on ram because on the program execute the function but can't load the image! Never the software or the windows crash when I executed the fucntion render image 3D on Software.
I attached the all log file. I think it is this information. I don't know how read this report.
(1) You are using 3D acceleration, hence the amount of graphics RAM assigned to the guest is barely relevant: the graphics are being rendered by the host, not the guest.
(2) You are using the official Guest Additions, but your software is the Ubuntu fork - you are not actually using VirtualBox. Uninstall the fork, install VirtualBox, and then lets see if you still have the problem. Note that if you don't want to use VirtualBox then we can't support on you the VirtualBox forums. For the fork you should look for support in an Ubuntu support forum.
(3) As mentioned, when you use 3D acceleration the graphics are actually rendered by the OpenGL drivers of your host. Success is therefore very reliant on the quality of host graphics drivers: make sure these are up to date.
