Download now 14 day, fully functional, free evaluation copy (1,335,922 bytes) of VWalk for Windows NT.

This preliminary release (1.0.0.2) of a standalone dwg viewer recognizes and displays the following AutoCAD entities:

LINE (if a line has 3D thickness, then it’s presented as a rectangle)
LINE3D
3DFACE
SOLID (old AutoCAD 2D entity, solid filled triangle or quadrilateral - don’t confuse with ACIS 3DSolid)
CIRCLE (if a circle has 3D thickness, then it’s presented as a cylinder)
3DMESH
POLYFACE MESH

BLOCKs, XREFs, POLYLINEs, ACIS 3DSOLIDs, TEXT and all other elements not listed above are not supported (yet).

Temporary workaround for viewing AutoCAD 3DSolids: export a solid drawing from AutoCAD to 3D Studio by using AutoCAD 3DSOUT command, then import the resulting file back to AutoCAD using command 3DSIN. This will create a 3DMESH representation of the 3DSOLID.

Only Modelspace elements are displayed (this is a 3D modelspace walkthrough software).

To start using the program press the <START> button on your Windows task bar, select VWalk and then VWalk.

The program starts with a registration dialog showing the serial number of the program that can be used for extending the temporary license and for an entering authorization code.

While on the temporary (evaluation) license,  press <Continue> button and it’ll take you to VWalk view window. Use the menu or toolbar to open DWG, BAK or DXF files for viewing.

Moving inside 3D space

Think of the viewing screen as a monitor connected to a video camera. By pressing keys on the keyboard or moving the mouse you will be moving the camera location and rotating it in 3D space, so that the view on your screen will change accordingly.

After opening the drawing file, drawing extents are calculated and the camera is positioned so that it shows your 3D design in a top view.

To rotate the view keeping the camera target point at the center of 3D drawing extents, you can point with the mouse cursor to the object on the drawing, press left mouse button and, while keeping it pressed move the mouse. It will feel like you are rotating the object - in fact you are rotating the camera around the object, thus changing the view direction.

The following additional movements of the camera are available by pressing the keyboard keys:

U – moves camera up
D – moves camera down
<UP ARROW> - moves camera forward (brings drawing closer)

<DOWN ARROW> - moves camera back
<LEFT ARROW> - moves camera to the left
<RIGHT ARROW> - moves camera to the right
P – pitch rotation
R – roll rotation
Y – yaw rotation

Please be patient with this primitive navigation: it is just the first prototype of our virtual vehicle; eventually we will add some on-screen steering instruments.
