CAD.OCX 1 is designed to draw and perform mathematical calculations for AutoCAD. CAD.OCX is an ActiveX Control written in Visual Basic 6.0 for doing things in AutoCAD like drawing lines, circles, arcs, rectangles, 3D spheres, and 3D cones.

The program can also calculate the length or midpoint of a line, calculate the midpoint of an arc, convert radians to degrees and vice versa, send characters to the AutoCAD command prompt, add single and multiple lines of text to a drawing, add a new layer, calculate the slope and angle of a line, and switch to model and paper space.

MYRIAD 3D Reader is a free application that views STL, VRML, 3D DWF and secure 3DF files created by MYRIAD.
MYRIAD 3D Reader is simple to use and runs as a desktop program or as an ActiveX component in a web page.
MYRIAD is a 3D model publishing and viewing system that solves the problems associated with distributing large native format 3D CAD models over the Web or networks to those who do not have access to the original files.
MYRIAD provides conversion of CAD models, where it ?presses? them into the highly-compressed, accurate 3DF (secure) format. Files are securely published with visual rights, including password protection and disabling of printing, cross sectioning, full logging, and the ability to expire published models.
The 3DF formats are viewable by MYRIAD 3D Reader and MYRIAD, which reads the published model and allows it to be visualized and analyzed, but not copied or modified.
MYRIAD 3D Reader does not use an application server, so scalability is not an issue. The published file sizes are so manageable, formerly huge models begin to display in just seconds. Because MYRIAD 3D Reader does not require a live session server, 3DF files can be downloaded or e-mailed and viewed off-line, just as with other popular Web publishing formats.
MYRIAD 3D Reader can also view VRML, DWF, STL, HSF and ICS formatted files.
MYRIAD 3D Reader is an executable that can be a desktop application, or as a component launched by a Web page. MYRIAD 3D Reader does not require access to a Web network to run, which means that CAD models can be viewed from the desktop or local network, as well as distributed outside the firewall via the Web to online trading exchanges, customers, vendors, suppliers, manufacturing bidders and more.
MYRIAD 3D Reader supports assembly structure visualization, with full 3D rotation, pan and zoom, model explode, part selection and identification, cut and cross section, and geometry measurement.
Main features:
- Easy to use
- Cross section and cut away
- Supports STL, VRML, 3D DWF and secure 3DF
- Explode assemblies
- View, rotate and measure 3D models
- Desktop and web browser (IE only)
