VectorDraw web library (javascript)是一個矢量圖形庫丨工業4.0推薦產品
VectorDraw web library (javascript)不僅能打開CAD圖紙，而且能顯示任何支持HTML5標準平臺上的通用矢量對象，如Windows，安卓，iOS和Linux。無需任何安裝，VectorDraw web library (javascript)就可以運行在任何支持canvas標簽和Javascript的主流瀏覽器（Chrome, Firefox, Safari, Opera, Dolphin, Boat等等）中。這意味著可以用DXF，DWG，DGN，SKP（Google的Sketchup），VDML等多種格式在任何臺式、平板電腦，智能手機和便攜式筆記本上展現出你的業務。打造智能3D設計方案，助力工業4.0人才賦能。
3D技術在建筑工程項目上的應用
1、革新了建筑項目管理的方式，節約預算所需時間和準確性，大大降低了設計圖紙會審的難度，在項目的早期發現設計和施工中的問題；
2、通過3D模型同步進行設計、成本與進度的協調服務，可以簡單迅速的調整結構上和設計上的改變；
3、提高了項目的可預見性，使各專業的協作能力大為提升，減少了效率低下、浪費等困擾整個建筑行業的問題。

VectorDraw web library (javascript) is a vector graphics library that is designed to not only open CAD drawings but also display generic vector objects on any platform that supports the HTML 5 standard, such as Windows, Android, IOS and Linux. It can be executed in every major web browser (Chrome, Firefox, Safari, Opera, Dolphin, Boat and more) that support the use of canvas and Javascript, without any installation. This means that you can show your work from many formats like DXF, DWG, DGN, VDML and more, on almost every Computer, Tablet, Smartphone or Laptop out there. VectorDraw web library is written exclusively in Javascript and runs on the client side, also it contains an object model similar to that of DXF and .Net VectorDraw Framework components.
VectorDraw web library (javascript)功能
VectorDraw web組件是一個革新性項目，其功能和性能得到了快速的提升。這意味著?VectorDraw web library ?一直在加入新的功能和發展潛力。使用VectorDraw web libary能展示2D圖紙，執行平移、縮放等視圖操作，獲取圖紙中的實體模型，編輯現有的實體模型或插入新的實體模型。任何支持.Net VectorDraw組件的實體模型都可以顯示，這表示所有.Net組件支持的圖紙都能以2D方式導出到新的web組件。當然，新庫中的對象格式與DXF和VectorDraw .Net相近。
VectorDraw web library (javascript)使用方法
這個web控件的核心是.vds格式。用戶必須使用vdfCAD或者VectorDraw開發人員框架庫將圖紙轉換為vds格式。VDS格式文件還需要上傳到服務器中，然后web控件（插入在網頁中的）才能將這個文件下載到用戶機器中并顯示。使用javascript，網站的開發人員可以獲得像表格、圖層、布局、實體模型、顏色、實體模型的幾何屬性等DXF文件，所有這些都可以為開發者使用。現在，這個web控件被視為擁有一些基礎編輯功能的、強大的視圖查看器，但是，它更是一個根據客戶需求，發展迅速的項目。
當你需要導出你的圖紙時，你需要進入（要么是vdfCAD，要么是VDF導出模式）我們生成的代碼LicVal中，并且這與打開圖紙的服務器位置有關。你需要為放置圖紙的獨立位置獲取LicVals。如果你沒有提供LicVals，打開圖紙到服務器時會顯示一個評估位圖。
What can it do?
VectorDraw web compoment is a revolutionary new project, its features and capabilities are being increased in a rapid frequency. This means that new functions and possibilities are added all the time. To this point using the VectorDraw web libary you can demonstrate drawings in 2D, execute view operations like Panning and Zooming, get specific entities from the drawing, edit existing and insert new entities to it. Every entity supported by the .Net VectorDraw components can be displayed without problems, this means that all supported drawings from our .Net components can be exported to the new web component in 2D. Also the object format of the new library is very similar to those of DXF and VectorDraw .Net.
How it can be used?
The key of this web control is the .vds format that we have created. The user must convert his drawings into vds format using vdfCAD or our VectorDraw Developers Framework library. VDS files must be uploaded to a server and then the web control(inserted in a webpage) is capable into downloading this file to the client's machine and display it. Using javascript the developer of the website will be capable into getting the file in a DXF like form. Layers , Layouts , Entities , colors , geometrical properties of the entities etc... all are there at the disposal of the developer. For the moment this web control is intended to be a powerfull viewer with some basic edit capabilities but it is a project that is evolving very quickly depending the requirements and needs of our clients.
When you export your drawing you will have to enter (either to vdfCAD either to the VDF export method) a LicVal which is a code generated by us and it has to do with the location on the server where the drawing is going to be opened from. You will have to obtain LicVals for the separate locations where you are going to place your drawings. If you do not provide a LicVal then an evaluation bitmap will be shown when you open the drawing to your server.
