Create static 2D representations of 3D models
To create static 2D representations of a 3D model, you can use any of the following commands: SOLPROF, FLATSHOT, SECTION, and SECTIONPLANE. Each of these commands are useful under different circumstances.

3D configuration in AutoCAD 2007
The 3DCONFIG command was substantially extended in AutoCAD 2007 and allows more detailed settings for 3D display and degradation of 3D scenes.
You can also verify the certification of your 3D graphics card for AutoCAD 2007.




3D solid model tip
Save intermediate stages of any 3D solid model that you create. This allows you to recover from errors more easily, retrieve components for analysis, and use a common starting point for several versions of the design.




Check your work in 3D
When working in 3D, it is an excellent idea to check coordinates, distances, and lengths of objects frequently. This avoids creating new objects based on incorrect ones.


Check your layers when working in 3D
3D solid objects created from 2D polylines or regions are always created on the current layer, not the layers of the original 2D objects.


Color settings for working in 3D
When working in 3D, avoid using index color 7 (white) for 3D solids. Objects created with index color 7 are displayed as black or white depending on the current background color, and you are more likely to change the background color with 3D models than 2D drawings. For white objects, use a True Color setting of 255,255,255 instead.

Create a planar surface in 3D
Use the PLANESURF command to create a planar surface by either selecting one or more objects that form one or more enclosed areas or by specifying the opposite corners of a rectangle.


Creating groups in 3D
When you need a temporary association of several 3D solids as an assembly or unit, assign the solids to a group.



Create walls in your 3D model
Use the POLYSOLID command to create walls in your 3D model. A polysolid is drawn the same way you draw a polyline. By default, a polysolid always has a rectangular profile, but you can add curved segments with the Arc option.


Make your 3D models semi-transparent
For a fast method to make a 3D solid model semi-transparent, click the X-ray Mode button on the Visual Styles control panel of the dashboard.


Making 3D DWG files smaller
By setting the SOLIDHIST variable to 0 you can make your DWG files (containing edited 3D solids) a bit shorter.
In a default setting, AutoCAD saves the editing history of 3D solids - i.e. the individual creator-objects (intersection, subtract...) for easier later re-editing. If you don't need this history, you can disable it using SOLIDHIST, with the BREP command or through the "History" setting in the Properties window (Ctrl+1).


Reducing visual clutter in 3D views
When working in 3D, it is usually easier to create solid models and avoid errors by turning shading on to reduce the visual clutter in 3D views.


Retain your 2D reference geometry and construction lines when working in 3D
When working in 3D, always retain 2D reference geometry and construction lines. These objects will be very handy for future additions and changes. If you want to retain the original 2D objects when you generate 3D solids, you can set the DELOBJ system variable to 0 (off).

Snapping while working in 3D
When working in 3D, it is very easy to snap to the wrong feature. Always zoom in to magnify object snap locations that are in close proximity to each other. The zoom feature on a wheel mouse makes this easy and dynamic.


Step and speed settings for 3D Walk and 3D Fly
The parameters for the interactive W-A-S-D keyboard walkthroughs can be set in the WALKFLYSETTINGS command (dialog).


Undocumented option in AutoCAD 3D editing commands
Some AutoCAD 3D editing commands (e.g. FILLET) support an undocumented option RESFIT (resolution fit).
Try to answer the prompt "Select an edge or [Chain/Radius]:" with the keyword RESFIT. AutoCAD then uses the value of internal resolution from its 3D modelling kernel ACIS/Shapemanager. Works in AutoCAD 2007, 2006, 2005, 2004.


Using blocks in 3D to enhance performance
When working in 3D, you can reduce the size of a drawing file by converting repetitive 3D solids into blocks. For example, for landscaping you can save a 3D representation a tree as a block and then insert it multiple times.
