GTX products from America are specialized software for converting paper design drawings into electronic format and processing them. GTX, located in Arizona, USA, is a world leader in drawing processing, especially in mechanical and engineering drawing processing. It uses artificial intelligence technology for raster processing, and IOP (Intelligent Target Picking) technology is a patent of GTX Company and has been adopted by many companies in the world. In the aspect of raster vectorization, GTX breaks through the technical methods adopted by traditional similar software, and adopts artificial intelligence technology, which greatly improves the accuracy and reliability of vectorization and reduces manual modification after vectorization.
Although CAD technology has been developed and popularized for more than ten years, according to the statistical report of IDC company in the United States, there are 8 billion design drawings in the world, of which only 13% is stored in CAD format, and 60% of the drawings are still on paper. In China, the proportion of paper-based design drawings will be higher, especially in some factories with a long history, which have accumulated drawings for decades and are the crystallization of enterprise knowledge.
At present, many domestic manufacturing enterprises have joint ventures or cooperation with well-known foreign enterprises, and a large number of drawings will be sent from foreign partners. For various reasons, these drawings are often paper media or raster files in tif format. Domestic partners need to edit these drawings, such as adding Chinese notes and schedules. How to edit these raster files is a difficult problem for these enterprises.
GTX software can easily edit raster files in tif format, not only edit raster graphics, but also convert Chinese, graphics, schedules and so on. Convert it into raster graphics in AutoCAD, and add them to the original tif format to form a graphic file that is different from the original one. In this way, GTX software can solve the problem of dealing with foreign drawings well.
Rich raster editing function
In terms of raster, GTX's unique IOP (Intelligent Entity Picking) is the most advanced method in the field of raster editing, which can identify raster entities like vector entities, so the editing function is particularly simple. In particular, arc vectorization can distinguish graphs in different situations and automatically identify circles and arcs with solid or dotted lines of different sizes. Other similar software may have to give the size of circle and arc in the parameter template, otherwise the correct result cannot be obtained. GTX can recognize symbols such as arrows, and post-processing such as large, small, thick and thin arrows can be processed in batches or modified separately by hand.
Powerful decontamination and smoothing function
GTX has the functions of decontamination, smoothing and disconnection. Especially in grating smoothing. The system provides the function of measuring stains or broken lines, which helps to adjust parameters to achieve more accurate decontamination. It also supports layering according to the thickness of the grating, which helps to separate tiny symbols or stains from the whole pixel.
Powerful capture function
In terms of capture, GTX provides 18 capture modes, and both raster-to-vector and raster-to-raster capture functions can be realized. Powerful snapshot function makes the operation more convenient and accurate for users.
Hybrid editing of raster vector and accurate combination of the two.
Mixed editing of raster vectors means that raster files and vector files match each other. In the same software, raster vectors can be displayed or drawn at the same time, of course, there will be no problem. However, if it is handled by a third-party software, such as the browsing software in the engineering drawing file management system, it may not be possible to identify that two files belong to the same drawing file logically. GTX is the most famous electronic drawing software in the world, so the browsing function of most engineering drawing management systems can be accurately combined with raster vector mixed drawings. And many other electronic drawing software will encounter problems.
Intelligent recognition graphics
Pixels such as lines, arcs, circles, dimension line, arrows, etc. can be distinguished intelligently, and can also be layered according to line type and line width. The completeness and usability of vectorization results are the best products in this field at present. Different from the "thinning" centerline method adopted by most other products, GTX's intelligent achievements are far ahead in the industry.
Intelligent character recognition (AI)
In terms of characters, GTX has the ability of intelligent character recognition. Users can train the system to recognize a certain character shape, even handwriting. After learning, the system can recognize characters very accurately, and the recognition of character intersections and broken pens still has a certain accuracy.
* Batch automatic vectorization and man-machine dialogue vectorization.
If man-machine dialogue vectorization is adopted, GTX will display the picked pixels in other colors first, and users can pick out the parts that are not used as vectors before formal processing. This product is also very powerful in rasterizing vector pixels. (as shown in figure 5)
* consistent with AutoCAD.
Because GTXRaster CAD series software is integrated in AutoCAD environment, all instructions, menus and toolbars are consistent with AutoCAD, and the user interface is easy to understand and use, especially for AutoCAD users. GTX Company has opened a large number of command raster operations and processing commands, which makes the operation of raster graphics very easy and efficient.
Similarity comparison
Because of its advanced technology, GTX vectorization takes up less space than similar software.
The IOP (Intelligent Target Picking) artificial intelligence technology adopted by GTX greatly improves the accuracy and reliability of vectorization.

Using GTX professional drawing processing software will improve the productivity of drawing design and quickly return the investment in CAD technology development and promotion for more than ten years. However, according to the statistical report of IDC, there are 8 billion drawings in the world, of which only 65,438+03% are stored in CAD format, and 60% are in paper.
With the rapid development of information technology today, in order to manage and utilize resources more efficiently and realize the efficient production of products, the electronization of drawings has become an indispensable part of an excellent enterprise. Many enterprises have adopted electronic document management instead of traditional methods. How to save, store and manage a large number of drawings and how to share this information with more people is a big problem facing many enterprises today. Electronic drawings have two storage formats, raster format and vector format.
Raster format: On a computer monitor, a picture is just a bunch of pixels with different colors. Some graphics file formats do record pictures in pixel form. These are raster images, which can only be edited by changing pixels directly with bitmap editing software.
Vector format: Vector graphics files are descriptive records of geometric figures, and these shapes are converted into bitmaps and displayed on the display. Vector graphics are easy to decorate and handle because its components can be moved, resized, rotated or deleted independently.
Vector format is an intelligent format, which can be edited and used efficiently and has high use value. Raster format is not intelligent format, which is not conducive to efficient editing and utilization of enterprises. According to the frequency of drawing reuse, our experts found through analysis that it is an efficient and ideal way to edit drawings with grating and convert them into vector drawings with grating vector editing. GTXRaster CAD series software consists of four functional modules:
* GTXRaster Tools: It is a tool to enhance the graphic quality of scanned images, including raster operation tools such as cleaning, calibration and smoothing, which is simple and easy to use. This is a powerful tool to clean up the layout of scanned images. Operating raster images in AutoCAD environment improves the design efficiency.
* GTXRaster CAD: AutoCAD, known as raster in the industry, is the most efficient raster processing and editing software. Especially for AutoCAD users, it can directly process and edit raster images under AutoCAD and integrate them into the current design work. It includes the functions of the GTXRaster tool.
* GTXRaster R2V: It is suitable for the conversion from grating to appropriate amount, with vectorization function as the main function, including the function of GTXRaster tool. In AutoCAD environment, it provides an effective raster cleaning tool and the function of converting raster images into AutoCAD entities and character recognition.
* GTXRaster CAD PLUS: contains all the functions of GTXRaster CAD, and adds automatic conversion (vectorization) function from raster to vector, powerful batch vectorization function and advanced intelligent character recognition function. It is full-featured software, including all the above modules. * Grating modification technology
The latest generation technology of GTX series products is IOP- intelligent picking, which was invented and patented by GTX company. Intelligentize non-intelligent raster pixels and treat them like CAD pixels. With IOP, the ability of grating modification is greatly increased, and users do not necessarily need to invest a lot of manpower and funds to vectorize drawings. (as shown in figure 6)
Let's take a look at other raster modification techniques, such as a technique called brush, which changes the pixels of a picture into black and white, or copies, edits and so on. This method can only solve some small problems simply. In the case of overlapping pixels (as shown in Figure 7), the geometric structure of the figure will be destroyed, and the energy consumed is particularly large.
After this method was put into the market, it was found that it could not solve the problem at all. Some CAD manufacturers combine CAD technology with brush technology, using brush technology to smear pixels and then using CAD technology to make up damaged parts. This method is more effective and efficient than the single brush method, but it will still destroy the geometric structure of the picture when dealing with misaligned pixels. (as shown in fig. 7)
* Vectorization technology
GTX uses intelligent recognition for vectorization, instead of using the centerline as most products do. Vectorization along the center line can easily turn a complete line segment or circle into several line segments or arcs. In this respect, GTX products are particularly superior due to IOP technology. GTX automatic vectorization method automatically converts raster images into CAD entities, and optimizes the process of raster entity recognition according to predetermined rules. Generally, it takes only a few minutes to complete A 1 drawing.
Let's take a look at other vectorization techniques, such as using the center line, using the peripheral line, and splicing the center line and the peripheral line in parallel.
The following are some comparative examples:
General software vectorization
Fig. 8 is the result of GTX vectorization. As can be seen from Figure 10, the vector technology with insufficient intelligence (centerline method) cannot identify basic pixels such as lines, circles and arcs. And it is difficult to maintain the geometric structure of the graph.
* raster vector hybrid editing technology.
This strategy is to locally select a part of raster images for cleaning and vectorization. The selected parts are converted into CAD entities through man-machine dialogue, and the drawings are processed by combining CAD operator technology and automatic vectorization technology. The patented technology of GTXRaster software uses artificial intelligence technology to identify and process the grating, which brings good news to users who are troubled by scanned images and foreign images.
