GETTING STARTED<br />

24<br />

This chapter contains sections helpful in getting started with the system setup and basic operation: “System<br />

Requirements”, “T-<strong>FLEX</strong> <strong>CAD</strong> System Setup”, “Basic Terms and Drawing Techniques”, “Quick Reference<br />

on User Interface”.<br />

System Requirements<br />

Hardware Requirements<br />

Computer: PC with USB port<br />

Processor: Pentium IV or compatible<br />

Minimum hard disk size: 300 MB<br />

Minimum RAM:<br />

Recommended RAM:<br />

1G<br />

2G or more * (for very large assemblies)<br />

* 32-bit operating systems Microsoft Windows have a limitation of 4GB of memory address space. This 4GB<br />

space is evenly divided into two parts, with 2GB dedicated for kernel usage, and 2GB left for application<br />

usage. Each application (including T-<strong>FLEX</strong> <strong>CAD</strong>) gets its own 2GB, but all applications have to share the<br />

same 2GB kernel space. For Windows XP and Windows Vista it is possible to increase the default<br />

allocation capabilities up to 3GB (3GB for user mode, 1GB reserved for kernel). Such capability requires<br />

additional tunings in order to be effective (see http://support.microsoft.com for more information).<br />

64-bit operating system Windows does not have limitations in terms of size of random access memory and<br />

does not require any additional settings to control it. Up to 4GB of memory is automatically allocated for<br />

32-bit applications (such as T-<strong>FLEX</strong> <strong>CAD</strong>).<br />

To fully exploit the capabilities of 64-bit operating system, there is a special 64-bit version T-<strong>FLEX</strong> <strong>CAD</strong><br />

x64. Combination of T-<strong>FLEX</strong> <strong>CAD</strong> x64 with Windows x64 allows using unlimited amount of random<br />

access memory in working with T-<strong>FLEX</strong> <strong>CAD</strong>.<br />

Software Requirements<br />
