If I see a classic article on the internet, do Tongji University-TongjiLUG have civil engineering projects? Alas, I am desperately trying to get rid of XP, but it is doomed to be entangled in this life ......

At present, domestic enterprises are not very automated, and most of them cannot use 3D images for direct processing and production. Therefore, 2D images are still the most fundamental production basis for most enterprises. In enterprises, converting two-dimensional graphs to PDF is a very important small step, because subsequent printing and communication between enterprises are inseparable from PDF documents transferred from two-dimensional graphs.
In 3D CAD design software, 2D graph to PDF is

When we actually use shuttle ESB in a project, we usually use the pub/sub mode. Next, we will explain this mode.
Note: Even the command-based request/corresponding mode can be implemented by publishing and subscription.
Currently, shuttle ESB only supports three Queues: Microsoft Message Queue MSMQ, sqlserver table-based queue, and rabbit MSMQ. The pub/sub mode of shu

I have read only the original English (or photocopy) books and some documents on the Internet in terms of design patterns. There are many proprietary terms in the design model. Because I don't know what part of the Chinese translation is, this article is wr
When dealing with custom events, the observer mode and the publish/subscribe mode are often used. When I first did not understand the implementation of these two modes, I read some information online, many introductions confuse the two modes and consider them as the same mode and implementation. Later I read some books on design patterns, and I feel that there are some essential differences between the two models, as shown below:
The observer mo

If the data in the database is updated in real time, and the report we use to evaluate it is based on such real-time data, then we can take the SQL Server Reporting Services (SSRS) service. A more superficial scenario is that we need to look at the sales data KPIs for the most recent day, week, or January and get the corresponding table or graph compared to the previous cycle, and the exact real-time sales data goes into the database. The advantage of this is that, for this functional requiremen

The coordinate system of AutoCAD is divided into world coordinate system and user coordinate system.

The world coordinate system is the default coordinate system defined by the AutoCAD System. When we open a new graph, we enter the world coordinate system. It is similar to the familiar dikar coordinate system. The horizontal axis is the X axis, the vertical

The main purpose is to use AutoCAD to draw graphics, so first of all to understand the Graphics object in the environment. As we have seen in real life, AutoCAD provides a three-dimensional space, and usually our modeling work is done in such a space.
