Superminis for Super CAD
Many second time users of computer-aided design software and hardware, in their efforts to have more power and flexibility, are switching to superminicomputers and building their own systems....
Mainframe Software on Micos�Finally?
Now that sophisticated analyses run on microcomputers, engineers should consider converting software originally written for mainframs on their micros. Tools for transferring software can...
CAD Goes into Analysis
In the past, computer analysis of a design was always a separate and distinct step from CAD. Now, an increasing number of systems are combining the two. One system, SSCAD, allows the engineer...
CAD Mapping Trailblazer
Until three years ago, few civil/surveying firms had automated both surveying (including digital recording of angles and distances shot in the field) and the related design and drafting....
From Micro to Supermicro
The Association of Central Oklahoma Governments found that simply replacing its microcomputers with supermicros wasn't enough to tackle large files of census tracts and other mapping data....
Structural Analysis by Spreadsheet
This is an introduction to and description of use of a spreadsheet to analyze a two-way slab on a microcomputer. The spreadsheet used is Lotus 1-2-3, but the ideas generally apply to many...
Building with Software
Project management has become a more precise art now that computers are on the construction scene. Scotsman Mfg. Corp. computerized its manual CPM techniques for erecting modular structures,...
