3D Viewer Window
Function
This command views in 3D, the selected 3D faces, polylines, lines
and points. This routine
uses the OpenGL graphics library for rendering, which gives it superior
performance. Some of it's
features include the ability to zoom in and out, pan, rotate around
the X,Y,Z axis and
shade in user-positioned lighting.
View Control
- Ignore Zero Elevations: When checked, the 3D viewer
ignore
entities at zero elevation.
- Color By Elevation: This
will color the contours or 3D faces by elevation. The elevation scale
legend is displayed on the left of the window.
- Vert. scale: Sets the vertical scale factor for the 3D
viewer. Flat surfaces can be exaggerated
by increasing the vertical scale.
This
control represents
position of the sun in the sky if looked from above. Therefore, the
position of the sun in the center means that the sun is in a zenith,
and position
near the
edge of the circle means that the sun is near the horizon. To move the
sun, simply drag
it to a new location, or click
on the new location. The slide bars on the sides are the intensity and
brightness of the display.
Zooms IN.
Zooms OUT.
Switch to Dynamic Zoom mode.
Switch to Pan mode. Click
and drag to pan.
Switch to Rotation mode.
Switch
to initial view.
Toggles shading on and off.
This is an inquire tool. Point the arrow to any entity and data such as
the layer, type, elevation, length, etc will be displayed.
Resets the 3D view to plan.
Exit the 3D viewer window.
- Clip Plane: This slider
will clip the image based on the location of the slider. When the
slider is all the way to the left, the entire image is displayed.
Moving the slider to the right will clip the image, going deeper as the
slider is moved to the right. This is useful to view items that are
hidden behind something else.
- Scroll Bars: Use X,Y,Z
scrollbars near the bottom to rotate the view. The range
of these scrollbars is -180
to +180 degrees with middle being 0 which is the default position when
the viewer starts. When the cursor is near the middle of the window,
the XY icon will allow for rotating the image with the mouse, while
holding the left mouse button. Move the cursor to the edge, and the
icon switches to Z. This allows for rotating around the Z axis with the
mouse, while holding the left mouse button.
Advanced
Tab
- Block Model Objects: This
option has three choices when loading block model entities. 1. To leave
as points. 2. To Render and 3. To prompt each time. If render is
selected, it will apply to all face objects such as a TIN or GRD.
- Block Model layers: This
will display the block color scheme. Colors of the blocks can be turned
on or off to view blocks in the middle.
- Shading Mode: There are 3
shading modes to render 3D faces. They are 1. Shade Front, 2. Shade
Both, and 3. Shade Back. This will render the top and bottom of the
faces if desired.
Export to BMP format.

Sets the AutoCAD view to
