The basic idea for AutoCAD’s graphic user interface (GUI) was to provide CAD users a choice of drawing methods that would best suit each user’s drawing experience and productivity needs. A powerful menu system allows users to draw, edit, arrange, print, or save a drawing on the fly. While other CAD programs had the ability to draw and modify complex vector graphic objects, CAD developers at Autodesk considered that the ability to edit a vector object was limited to the purely vector-based method. Although vector-based graphics have advantages over traditional raster graphics in some scenarios, users have no way of modifying vector objects within the same drawing that created the object. AutoCAD’s designers therefore developed the ability to edit vector graphics within a traditional 2D raster graphics environment, which they considered to be the most familiar CAD interface method.
According to Autodesk, the AutoCAD user interface was inspired by the work of some of the first CAD users. Users could insert or modify objects or layers on the fly without the need to save the drawing first. CAD users would often watch a CAD operator in action, noting the user’s work habits and eventually adapting the CAD work process and tools to fit the way the user worked best.
1941: Autocad developed by Charles McCabe in the U.S. Navy, following a family tradition that dated back to 1830 and another earlier design related to the occupation of welding. McCabe, who was the son of a welder and worked for the U.S. Navy as a draftsman, used his welding skills to develop the first CAD program. While developing the program, McCabe also served as the National Designer for the U.S. Navy.
1942-1944: The U.S. Navy tested and refined Autocad, with some features including:
It was designed as an electronic drafting system that allowed drafting to be done on a computer that would not require a drafting table.
It was developed with a six-track punch tape recorder so that operations could be done directly in front of the computer screen.
The design editor was developed to allow drafting to be done directly in front of the screen and was developed with the purpose of removing the need for the drawing table or graph paper for drafting.
1944-1945: The U.S. Navy adopted Autocad and its design editor, and became the first military department to use the system.
In addition, there is an API in MS-Access, Microsoft Query, Microsoft MDX, Microsoft DAX, which allows importing and exporting data to and from the drawing file.

Alterations in mitochondrial ultrastructure, mostly in the form of morphologic changes of mitochondrial cristae, were investigated in the myocardium of patients with ischemic cardiomyopathy by using electron microscopy. Light microscope analysis of hematoxylin and eosin-stained samples revealed that the myocardium in such patients was characterized by subacute and chronic stages of congestive myocarditis with marked interstitial infiltration of mononuclear cells, interstitial edema, and inflammatory lesions with fibrous tissue proliferation. By electron microscopy, mitochondrial cristae were not observed, but the matrix contained amorphous electron-dense material in nearly every mitochondrion in most of the studied patients. Additionally, besides the amorphous electron-dense material, there were other ultrastructural features, such as hypertrophic mitochondrial membranes, multilamellar bodies, rough endoplasmic reticulum, and lipid droplets within mitochondrial matrix, suggesting that the mitochondria might be more active in the pathological myocardium of ischemic cardiomyopathy than suggested by a previous study using transmission electron microscopy.Isolation and characterization of a thermostable β-agarase from Thermobifida fusca WSH062.
A thermostable agarase, ag43, from a hyper thermo-tolerant strain, Thermobifida fusca WSH062, was purified to homogeneity by a one-step chromatographic method using Sephacryl S-200 HR column. It showed an apparent molecular weight of 43.0 kDa on SDS-PAGE analysis. It showed optimal activity at pH 5.0 and temperature 55°C. ag43 exhibited stable pH activity and retained 25% of its initial activity after 2 h incubation in pH 3.0-9.0 at 37°C

Don’t miss EW’s supercut of all of the most controversial moments from Game of Thrones’ fourth season.
Game of Thrones is quickly approaching its shocking finale, and one of the season’s most controversial moments involved Ser Davos. On Thursday’s episode of Vulture, we saw the sneaky, manipulative turncoat reveal that he’s in love with Sansa Stark. EW’s Dyson Hines has a supercut of all of the major, shocking moments in the last two seasons, where one of the show’s most important characters changed for the worst. Check out our collection of the dramatic turns in the video below.
When using a GUI display in C#, what should I do with the cursor?
When using a GUI display in C#, what should I do with the cursor?
I need to know when the cursor is on a button.
All GUI elements have a Cursor property.
MyButton.Cursor = Cursors.Hand;
Which is the only cursor supported by the windows. See
12. There are two types of name of the week. The first is called « name of the week » or « nth name of the week ». The second name is « name of the year ». These names are randomly chosen from the birth names of all the people born in the past week.
The « name of the week » is chosen after 3 days, and the « name of the year » after 1 year.

What’s New in the?
Incorporate documentation and user requirements directly into your designs. Use Markup Assist to generate separate sections in drawings to create documentation and annotate your drawings with requirements for other users. (video: 1:22 min.)
Gain a better understanding of your designs by annotating them on screen. Instead of using markers and pens to mark objects, you can create, edit, and delete annotations directly from the command line. Use AutoCAD features like a floating legend to mark up any drawing element, select parts to highlight for editing, and apply styles for the different types of annotations. Annotations are saved to the same drawing as the original object and automatically syncronized to the most recent version of the original object. (video: 1:19 min.)
The 2018 release of AutoCAD included several major enhancements to its new 3D drafting features:
Select A, Match A, and Remove A:
With the A-tools, you can now edit select objects in 3D. Create a selection from a single object, or choose multiple objects and create a union, intersection, difference, or exclusion between them. (video: 1:37 min.)
Clone 3D Parts:
Clone 3D parts without converting your drawing to 2D or 3D first. Clone any 3D part, cut, rotate, and scale it, and use it to extend, resize, and reposition other parts in your drawing. (video: 1:42 min.)
Layer 3D Parts:
Make 3D parts of specific types on top of other layers, even as you edit your layers. All parts of a specific type (for example, surfaces) will appear on top of any other 3D objects and layers in your drawing. (video: 1:54 min.)
Keyboard Shortcuts for 3D Selection and Manipulation:
With the A-Tools, you can now create selections using the up and down arrows, as well as the X, C, and V cursor keys. Save time with the 3D Orbit Viewer, which provides a bird’s-eye view of your drawing with the ability to quickly toggle between horizontal and vertical or orthogonal views. (video: 1:48 min.)
Navigate while drafting using the keyboard and toolbars. Using keyboard shortcuts and the Drafting toolbar, you can navigate your drawing without moving your view. (
