Similarities and differences of construction and software engineering
Pao Yi November 2002
Architecture is an ancient industry, starting from the pyramid, has been thousands of years of history; Software is a new industry, engineering is only 40 years old. But the software industry absorbs a lot of nutrients from the construction industry, such as patterns. The author also has two construction and software industry work experience, two industries for a simple comparison,
Traditional mechanical drawing is to imagine the three-dimensional shape of the parts, and then the three-dimensional model from all directions projection, generate the projection surface of the two-dimensional view, dimensioning and other annotations to generate basic two-dimensional drawings. The following figure.
But the shortcomings of two-dimensional drawings is also obvious, is slightly more comple
of a string. Start can be of the bigint type.
Length
An integer that specifies the number of characters or bytes of the expression to be returned. If length is negative, an error is returned. Length can be of the bigint type.
3. Remarks
The offset (start and length) of the ntext, char, or varchar data type must be specified by the number of characters ). The offset of data types such as text, image, binary, and varbinary must be specified by the number of bytes.
4. Example:

function of the part module is based on the operation mode of the parameterized and characteristic model, and the new standard of the solid model which is easy to use is established.2 Solid Edge applications at all stages of product improvement development2.1 Create three-dimensional entity diagram using product two-dimensional design drawingsFirst open the previously generated. dwg format file using the drawing module of SE (which is represented as solid edge in SE), click on the "View" button

Scenario: Mobile product design in Silicon Valley Internet company.
8:30 am, to the company, eat breakfast, the first floor café to get a cup of iced coffee, upstairs.
9:00 am, to the office, look at the email, row their own day design work, marking the focus.
9:15 am, centralized processing requires a person to think about the design of the problem, painting on paper, writing content design ideas, indesign,ps,omnigraffle.
10:00 am, quick meeting, and product manager, development together
This tutorial for you to see the drawings (DWGSee Plus) Use of the problem, I hope to help.
Q: With a look at the drawings in Vista and Win7 under the browse some drawings appear garbled, how to solve?
A: Generally due to the lack of fonts, Vista and Win7 under the lack of imitation fonts and italics and other causes. The solution to this problem is to download
effectively.
This software not only has the strong solid modelling, surface modeling, virtual assembly and the production of engineering drawings and other design functions; Moreover, the design process can be carried out by finite element analysis, mechanism kinematics analysis, dynamic analysis and simulation, improve the reliability of the design, at the same time, can be established three-dimensional model directly generate numerical control cod

The application of the wiring management software has changed the way of manual wiring management, which helps the network manager to better understand the structure of the wiring system,

Unnecessary efficiency considerations are often the root of the evils of performance problems. --william Allan Wulf
In the 12th chapter, "Curvature of velocity" we learn how to use instruments to diagnose core animation performance problems. There are a number of potential performance pitfalls when building an iOS app, but in this chapter we'll look at performance issues related to drawing .Software drawingsThe term drawing typically refers to a software drawing in the cont
time according to their different needs, which imposes strict requirements on management personnel. However, the function of Integrated Wiring management software is far greater than that of using the tables and corresponding tables compiled by office automation software such as "WORD" or "EXCEL" to express the corresponding relationship of integrated wiring.
Today, network users are changing rapidly, so they can be changed and adjusted at any time according to their different needs, which impo
How do I convert a CAD drawing into a PDF file in the CAD editor? In the ordinary work, the architect with the help of the CAD editor without editing a CAD drawing needs to be viewed, but the CAD drawings are in DWG format, so it is not convenient for us to view, many times we need to convert CAD drawings into PDF files, so that we can easily view, But how do I convert a CAD drawing into a PDF file in the C

Some time ago, a senior engineer threw out a question about the internal network management of the enterprise. Let's take a look:
1. The final draft of the company's new product drawings has not yet been confirmed, and competitors have listed them in batches based on the first draft of the design;
2. Over 90% of employees share shares on the internet, watch news, watch short videos, play games, find jobs, and send resumes with the help of convenience
other orders. It is necessary to ensure the rational use of existing inventory, and ensure that the special materials corresponding to each customer's order will not be mixed.
Ø Outsourcing Management
Many MTO Enterprises require external association management. Outsourcing methods include outsourced external processing, outsourced processes, and outsourced procurement. For example, some enterprises provide Blank materials to external suppliers, and the External Manufacturers process the workpi
requirements.
Designers often want to design a design that is beyond their needs, hoping that the design can meet future demand changes. this is wrong, at least at this stage. if you want to meet your future needs, you should increase your needs in the demand phase, rather than thinking about changes in the design phase.
