Graphic objects such as lines, arcs, text, and callouts are objects.
Style settings, such as Linetype and dimension styles, are objects.
Organizational structures such as layers, groups, and blocks are objects.

PDF conversion problems (iii). Converting AutoCAD drawings into PDF documents
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 enterprise
Autodesk is crazy. It was sold out during a big jump. We had to buy n sets of AutoCAD Civil 3D, but now we only need 6000 pieces. :) I will not sell them, just take this opportunity to introduce the AutoCAD Civil 3D product.
AutoCAD Civil 3D can be said to be a 4-in-one product. First of all, it was built based on AutoCAD
Because in the project you need to extract the attributes from the title box in the AutoCAD DWG file into the database to realize the bulk of the drawings.
At the beginning of the online search for this information, some of the controls can be separated from the AutoCAD system extraction, but are charged. For example, OPENDWG is used more. But to pay for membership can be used. So I want to analyze DWG's f

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

In a technical forum to see a friend mentioned such a question: how quickly in AutoCAD to draw multiple concentric circles? To this question Netizen's answer is various, has the reply to say with the deviation command, has the answer with the array ... Of course, there are friends. Presents a more practical VBA solution and AutoLisp solution.
I think that the use of VBA or AutoLisp as a solution is of course a very good way, but since the landlord ra
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
