• Performance up to 60 times faster.  A new drawing engine takes advantage of GPU-based graphics cards so speed increases dramatically.  Larger files will pan, orbit, and zoom in and out smoothly.
• Easier, more powerful layer management.  Design Director simplifies layer management, and new layer filter support (.DWG compatible) lets you manage large, complex drawings with ease.
• Fewer clicks.  Double-click on text or M-text to enter edit mode.  Edit blocks and groups in place.
• Less setup.  New and improved templates set default values to more commonly used settings.  Paper space layouts can be copied with all settings from one drawing to another.

• Floor plan design is faster than ever.  An improved Wall tool now allows for definition of intelligent relationships between walls to link or not link, clean or remain separate, in any combination.
• Create any style of door or window easily.  ACA compatible Door and Window Muntins expand options for parametrically creating the exact object types for your design.
• Create precise shapes for walls.  A new bottom wall modifier gives you even greater control over the look and design of your structure's walls.

• Geometric Tolerances enable precision in communication.  The completely rewritten tolerances tool provides specific instructions on production tolerances and is .DWG compatible.
• Parametric Parts can be easily created.  Drawn parts can be made into reusable parametric parts with a more robust part wizard.  Parts may also be scripted using even more commands and mathematical functions than before.
• Better communication with multi-leaders.  Use one callout for multiple parts.

• Ruby Scripting.  Create customized scripts to automate tasks and work more efficiently.

• Work with the latest AutoCAD® files.  Added support for .DWG 2010/2011.
• Better Google™ SketchUp™ workflow.  Support for Google SketchUp v8 and significantly improved COLLADA (.DAE) export feature that includes instances so that blocks and architectural objects will be read by SketchUp as components.
• More powerful Xrefs.  We've added Xref clipping for dozens of file formats and allow binding of Xrefs, which can then be exploded and edited.  Xref layers are easier to manage with layer filters.

About DoubleCAD XT PRO v3

2. 5D DoubleCAD™ XT Pro is an AutoCAD LT work-alike that goes beyond AutoCAD LT in terms of 2D and 2.5D CAD capabilities, especially in the area of drafting and detailing.  Most significantly, DoubleCAD XT Pro takes advantage of GPU-based graphics cards for increased performance of up to 60x.  Pro v3 also includes powerful scripting and an innovative Drafting Palette that expedites the drafting-to-detailing process by creating fully associative, 2D views and hatched sections (even from xrefs) from 3D models.  Other unique features include geometric and pattern constraints (lightning-fast "what if" design scenarios), drawing compare, hatch pattern creator, clip 2D detail sections, a range of intelligent (parametric) architectural objects, design director, and parametric parts manager, as well as self-healing walls, self-aligning blocks, advanced handle-based editing, snap prioritization, transparent fills, draw order by layer, hide objects regardless of layer, ability to imbed image files, revision cloud, batch file conversion, smart dimensions, and viewport exploding.  DoubleCAD XT Pro v3 also has a number of useful 2D CAD tools not found in AutoCAD LT or AutoCAD, including special line, arc, and circle tools, enhanced command line, bezier curves, fixed ratio ellipses, and bisector line tools.  The product has a fully customizable interface and includes one of the widest varieties of file filters in the CAD industry, including support for .DWG (AutoCAD R14 to 2011), .SKP, .DAE (Collada), .SAT, .3DS, .OBJ, .IGS, .STEP, and more.  DoubleCAD XT Pro v3 includes premium customer support and is $695 ($199.99 for upgrade).
