MicroCAD 2.0 - Summary of Changes in Version 2.0 (June 1992)
------------------------------------------------------------
The following is a summary of changes between versions 1.1 and 2.0.
For a summary of changes between versions 1.0 and 1.1, refer to
BULLETIN.201. Note: Information in BULLETIN.111 is no longer
current. For full updated instructions, refer to MICROCAD.DOC.
Diagram Export (DXF)
--------------------
Diagrams are now automatically exported in DXF format. Both 3-D and
2-D exports are available, to accommodate the capabilities of various
receiving programs. Refer to section 5.3 for details. Additional
information on the DXF implementation is contained in section 8.5.
Auto-Dimensioning
-----------------
The dimensions of each line, rectangle and cube may be displayed on
the diagram. The dimensions are updated dynamically as objects are
created or resized. Dimensions may be displayed in whole numbers,
tenths, feet & inches, or inches & 16ths. Refer to section 4.18.
Expanded File Format
--------------------
The maximum number of objects per diagram has been increased to
approximately 1500. Diagrams are now saved as individual files.
The new file format uses substantially less disk space. Existing
diagrams will be automatically converted to the new format the first
time the program is run.
Orthogonal Rotations
--------------------
Diagrams may now be rotated in 90 degree steps, in either the
vertical or horizontal plane, by clicking on the axis windows. This
function may be used to display or add additional objects from the
top, bottom, back, or sides of a diagram. Refer to section 4.19.
Additional Line Types
---------------------
The dotted line function has been expanded to include seven additional
line types: hidden, center, phantom, dot, dash-dot, border and divide.
Landscape Mode
--------------
HP LaserJet landscape mode has been added to the previously available
portrait mode.
Overlay Grid
------------
The overlay grid been changed from quad-ruled to dotted. The spacing
remains 10. The grid now coincides with the axis lines, and both may
now be used simultaneously. Objects drawn while the grid is on are
now automatically aligned to the nearest grid point.
Icon Changes
------------
The Grid and Background Color icons have been merged. The Product
Info function has been given its own icon, and now includes both
forward and backward browse. The Cursor Speed Adjust function has
been moved to the Perspective icon. The Linear Dimensioning function
has been added to the Axis Windows icon.
Perspective Projection
----------------------
The perspective projection algorithm has been changed to yield a more
technically accurate image.
OS/2 2.0 Support
----------------
The 80386 and 80486 processors are now recognized when running in
virtual-8086 mode.
Mouse Support
-------------
Support has been added for Logitech mouse driver release 6.10.
