|2Basic Interface Concepts||2-i INTRODUCTION|
|AutoCAD and ADT Pull-down Menus used in this
Illustrated to the right are some of the primary pull-down menus used in this guide. Though the Architectural Desktop 3 Presentation Guide discusses the process of Rendering Architectural Desktop objects, most of the concepts come from the AutoCAD side of this product. In other words, Rendering is really a feature of AutoCAD not Architectural Desktop.
With that in mind, this guide will focus on the process of Rendering and what it takes to produce good presentation images regardless of which of these two programs you work with. This is a particularly valid approach since Architectural Desktop still cannot produce all of the design concepts you may wish to present. In the Architectural Desktop 3 Pre-Design Guide the subject of Modeling with Solids and Surfaces is discussed so that the designer has greater flexibility in producing some of the concepts that ADT has no tools for ( terrain, for example ).
For Architectural Desktop users, this guide refers to AEC Objects when there is a specific need to address such objects as they may differ than any other Solid or Surface object in AutoCAD. The primary topic of interest for ADT users regarding Rendering has to do with the complex nature of many AEC Objects whose structure involves Entity Properties and Component indexes. The Components are set by default to use unique Colors but can also be set to use unique Layer Names and both methods of organization are important for the process of managing Material Attachments.
The Architectural Desktop 3 Presentation eGuide represents the 3rd in our series on Architectural Desktop. Though it can be used as is it is highly recommended that you also have access to the Pre-Design and Development eGuides. Throughout this guide you will find links to both of those guides ( particularly the Pre-Design eGuide ). You will not be able to access the other guides without an account.
The View pull-down menu provides access to 90% of the content discussed in this Guide: the Display and Rendering tools. From the Insert pull-down menu, we will look a Xref's and Blocks. From Architectural Desktop's Documentation pull-down menu we will look at the Perspective tools. We will also be looking at the Object Style tools.

Right-click pop-up Menu Layout
When working with Architectural Desktop Objects for Rendering purposes, having quick access to the Display Properties becomes a very important feature so you can identify and/or modify the object Components for Material Attachment. Illustrated to the right, I show how easy it is to access the Display Properties when the Shortcut Menu option is enabled on the Right-Click Customization dialogue box.
Be sure not to deactivate right- click pop-up menus on the Options dialogue box because you will certainly be cheating yourself of access to invaluable right-click features. When working with ADT objects, the right-click menu becomes even more important; almost acting as a guide letting you know what some of the options are for any selected item.
If you have pop-up menu problems, see OPTIONS, User Preferences tab and Right-Click Customization button.
If you must have some of the old AutoCAD functionality out of your right mouse button, you can set the Default Mode to Repeat Last Command and possibly even the Command Mode to Enter, but do not set the Edit Mode to Repeat Last Command. Always keep Edit Mode set to Shortcut Menu.
and ADT Toolbar Access
Illustrated to the right, I show some of the primary ways to acquire rapid access to the numerous toolbars that you will probably be using as you prepare your Model for Rendering. Since the Render toolbar is on the AutoCAD side of the program, you will only find it on the AutoCAD pop-up menus.
If you don't have any of Architectural Desktop's toolbars up on the screen, you will either have to use the Customization dialogue box or right-click on any unused "gray" toolbar area under the pull-down menus or on docked menus; as shown in the illustration to the right; use the AECARCHX > fly-out option.
You can also use the Customize dialogue box, introduced in AutoCAD 2000i, to access any toolbar at any time. To access the Customize... menu option, you can Right-click over any AutoCAD button or unused gray area on toolbars. You can also use the View and Tools pull-down menus to achieve the same result.
Most of the Aec Objects in Architectural Desktop are controlled by a 3-part display system that provides the means for representing objects, such as doors, in a conventional Plan view from the Top and in a fully articulated 3D view from an isometric vantage point. Though some of the Display Representations change automatically depending upon the View you use to work in, there are times when you will want to change the Display Representation to match the needs of your current task. In this eGuide, the discussion is all about Presentation and most of that will be in 3D so you may find that the "Render" Display Representation or equivalent 3D Display Representation ( if you have a custom one ) will be the best one to use for this portion of the project phase.
In some cases, such as that of using the Mapping tool for controlling how material map across the surface of an object, you may find that it will not read some of the Aec Objects unless the Display Representation is set to Render.
|3Options and AEC settings||.3-i INTRODUCTION|
|System Display Properties
Before you start to generate those amazing Rendering with hours and hours of labor spent to get every tiny detail just right, you should make sure that what you generate actually looks the way it should.
In Rendering, your system display configuration becomes even more important than ever. Rendering output can be at enormous resolutions with True 32bit Color so you should always check to see if you are actually seeing that output should you produce it. Illustrated to the right, I show the Control Panel with the Display Properties dialogue box opened.
On the Settings tab of the Display Properties dialogue box, check your Colors setting and the Screen Area setting for optimum Rendering Work. When Rendering, you should always run the maximum Color setting ( hopefully you system supports 32bit Color ) but as you increase the Screen Area, Colors are often automatically limited. The inverse can also be true; as you increase the Color setting, the Screen Area maximum size is reduced. This occurs because there is a greater load on your system's resources to produce such a vibrant display. While you are testing Renderings on your screen, keep in mind that more Screen Area is equivalent to more pixels which equates to longer Rendering times. This is not desirable at any time but especially not when running numerous tests. Perform tests and decide what provides the best working environment. Personally, I never run a display under 1024x768.
Though this Guide will does not discuss system requirements and configurations beyond this subject, you should also confirm that you have a good monitor, a lot of Ram, a lot of extra hard-disk space and the best Video Card you can justify. The more Ram on both the Video Card and on your system, the better.
|AutoCAD and Architectural Desktop Options dialogue box
The Options dialogue box, formerly known as Preferences, is an important part of producing high quality Rendering and Presentation work. AecFacetRes for Architectural Desktop objects and FacetRes for Solid Modeling objects are two examples of settings that make a tremendous difference in the way curves surfaces appear when Shaded and Rendered.
All of the settings with icons in front represent current drawing settings and will not be set for all of Architectural Desktop; i.e, they are local and not global settings. If you save these settings in a template file though, you can use them in a more global fashion.
For Rendering and Presentation work there are numerous Display Options that you will want to know about. Most Display Options that improve the appearance of objects on your screen do so at the cost of performance with respect to your computer. This means that you should exercise caution when experimenting with the Display Options discussed in this guide and make note of what changes you make and how to reset the default settings.
To learn more about the Options that affect the work discussed in this Guide, read the Appendix, Part X - Options Configurations
and Architectural Desktop Render Preferences
The Render and Render Preferences dialogue boxes offers numerous options and settings that affect the appearance, size, resolution, quality and destination of your Renderings. If these options are not properly understood and set, you may be loosing out on a lot of the hard work that goes into Modeling, Adding Lights and Attaching Materials.
One of the most important options to understand on these dialogue boxes involves the differences between the Rendering Types: Render, Photo Real and Photo Raytrace. Though Photo Raytrace offers the highest quality images, it comes at a price and may not be the Rendering Type you need for all Renderings.
To learn more about the numerous Rendering Options, read Part 5 - Rendering.

|Choosing an ADT Template
This Guide was written to assist you in your Rendering work no matter where you are in the process but it was also written to take you from the completed phase of a Model through to a completed Rendering. Therefore, you can start with Part 1 - View and begin the process of creating your Model while referring back to this guide as your Model evolves.
You can also start with a completed Model; which should prove to be a more logical approach. Included with this Guide is a sample Architectural Desktop Model based upon the acclaimed Barcelona Pavilion - illustrated to the right. If you decide to use your own completed Model or the sample Model, you should refer to Part 10 - Scenes before any of the other parts. In Part 10, you will find a complete overview of the whole Rendering process - from Xref'ing a Model to producing a Rendered image.
If you choose to start from scratch, using the "AEC arch (imperial - intl).dwt" or "AEC arch (metric - intl) template file is highly recommended. Many of the sample images and screen captures in this guide are based on these two template files. Though you can use any file you wish it may make the process of learning easier if your ADT objects behave and appear the same as those in this guide.
