The first release of AutoCAD Activation Code had only the basic ability to draw vector lines and basic, 2D drawing capabilities. AutoCAD introduced the capability to place text and other annotation in the drawing, which was a revolutionary advance over prior versions. The ability to place drawings on the screen in multiple views, and to zoom and pan in 3D scenes is another major innovation. AutoCAD introduced drafting and BIM capabilities and features that are often considered essential by the majority of CAD operators, and has become the standard in the industry.

Revolutions in the design process

The revolutionary nature of the software, along with the introduction of a mouse, led to the development of new conventions. A user would take a pencil and an eraser and draw on the screen. The user would place a command (menu item) to make the workstation give commands to the software. There were many commands that came with the package, and the user had to figure out which one to use.

The first AutoCAD drawing saved in the file, in 1982. Other programs such as Adobe Photoshop were also drawing editors, but users created the master drawings in AutoCAD, and then created the output drawings with other applications.

Starting in 1986, Autodesk introduced several innovations. By adding an optional drawing area, for example, users could draw in 3D, and the workstation software could help automatically set up the properties of 3D objects. The ability to zoom and pan in 3D drawings made the process of drawing 3D from scratch much easier.

By 1987, other important innovations were being introduced. The ability to change the paper type, move objects from one drawing to another, and to draw with a brush, instead of a pencil and eraser, was well established in other CAD programs. These innovations also had the side effect of speeding up the process of creating drawings, as objects could now be dragged and dropped in any order. The user could also use a paintbrush to edit existing drawings.

In AutoCAD 2.0 in 1988, version control was introduced, which made the process of sharing drawings much easier, and introduced a programming language for controlling the workstation. Users could now easily save the work of other users as templates and then reproduce the work at will. This is still an important feature of AutoCAD.

As users became more familiar with these features and conventions, the tools evolved. Features like undo, shortcuts, and flyouts were developed and added to help the

History

AutoCAD (1987–2004)
AutoCAD (originally called AutoLISP, a markup language developed by Autodesk) was first released on October 1, 1987, and was later renamed from AutoLISP to AutoCAD in June 1996. The first version was only available for the 16-bit Windows platform. The first version for the Macintosh was the 1998 release of AutoCAD 9.5.3. The last AutoCAD 16-bit release was AutoCAD 2003, which was released on September 27, 2004, and no longer supported AutoLISP.

How to replace values from a data frame to null values of the same name (column) in pandas?

What I want to do is find all the values in a column of a data frame that is not None, and replace all those values with None.
I tried using the mask method, but that is replacing all the values.
import pandas as pd
df = pd.DataFrame([‘a’, None, None, ‘b’])
df.columns = [‘i1’, ‘i2’, ‘i3’, ‘i4’] df.replace({‘i1’:None, ‘i2’:None, ‘i3’:None, ‘i4’:None}, inplace=True)

A:

You can try:
In [46]: df.replace({‘i1’:None, ‘i2’:None, ‘i3’:None, ‘i4’:None}, inplace=True)

In [47]: df
Out[47]:
i1 i2 i3 i4
0 a None None None
1 None None None None
2 None None None None
3 b None None None

A:

Use np.where:
df.where(df.isnull(), None, axis=0)

array([‘a’, None, None, ‘b’],
dtype=object)

A:

Use Series.mask with DataFrame.where:
df = pd.DataFrame([‘a’, None, None, ‘b’])
df.columns = [‘i1’, ‘i2’, ‘i3’, ‘i4’]

What’s New in the AutoCAD?

Drawing Lines:

With AutoCAD 2023 you can draw on closed, open or intermediate solid geometry, and apply any of the Standard or Array drawing conventions. When you’re working with closed solid objects, draw on an area of those objects as you would any other area of the object, using the techniques for drawing basic lines.

When you draw on an open solid object, draw on an area that is not part of the solid; the open area is called a hatch. When you draw on an intermediate solid object, draw on an area that is a region of an intermediate solid but is not part of the solid. The open area is called a hatch.

When you are drawing on an open solid object, you can use these methods:

Hatch mode: Draw on open solid objects using an open hatch. When you’re in hatch mode, you can draw in multiple layers. You can also use the standard selection tools or one of the layers tools to select parts of the open solid. You can also use the selection tools to select multiple open solids.

Solid selection: Use the selection tools to select an open solid, creating a selection that includes all the parts of the open solid. You can use the selection tools to select multiple open solids.

Freehand mode: Draw on an open solid object without creating a hatch. When you’re in freehand mode, the pen moves freely without causing the object to change shape. You can select parts of the open solid or multiple open solids in the same drawing session.

When you are drawing on an intermediate solid object, use the following methods:

Selection mode: Use the selection tools to select an open hatch or a part of an open solid. Use the selection tools to select multiple open hatch areas or multiple open solids.

Freehand mode: Draw on an intermediate solid object without creating a hatch. The pen moves freely without causing the object to change shape. You can select parts of the intermediate solid or multiple intermediate solids in the same drawing session.

Markup mode: Create a markup area that has not been converted to a hatch or open solid. You can draw on the markup area without creating a hatch. When you’re in markup mode, you can select multiple markup areas in the same drawing session.

Warping and Diffuse Directional Light:

You can warp or diffuse light using the Directional
