In late March, Autodesk unveiled AutoCAD 2017, the 31st release of its flagship sản phẩm. The new version sets the stage for Autodesk’s move sầu away from a perpetual license mã sản phẩm (in which you own a copy of a particular release of AutoCAD và can use it essentially forever) and lớn a subscription Model in which customers rent the software on a monthly, quarterly, annual or multi-year basis. As such, a lot of the effort in this release was done behind the scenes lớn smooth this transition.

That is not lớn say that there aren’t some very significant enhancements in AutoCAD 2017. In fact, there are three really big changes, and the first two involve dimensioning — sort of. AutoCAD năm nhâm thìn introduced an entirely new tool for creating all types of dimensions using a single comm&. For the first time, you could create multiple types of associative sầu dimensions without having to lớn over one comm& and start another. You could also place all those dimensions on a specified layer rather than having to lớn first make the appropriate layer the current layer. But last year’s improvements did not include centerlines or center marks. Those objects remained largely unchanged from when they were first introduced more than 20 years ago. As a result, centerlines and center marks continued khổng lồ consist of lines that once drawn were entirely unrelated to lớn the geometry they were used to lớn annotate. With AutoCAD 2017, that situation has finally changed.

Associative sầu Centerlines and Center Marks

AutoCAD 2017 introduces powerful new tools for creating and editing centerlines & center marks and these new tools appear prominently on the Annotate ribbon. The Centerline tool creates centerline geometry of a specified linetype that remains associated with the selected lines and polylines. The new Center Mark tool creates an associative sầu center mark at the center of a selected circle, arc or polygonal arc. Once created, if you modify the associated objects, the centerlines và center marks update accordingly.

The appearance of the centerlines & center marks are controlled by a number of new system variables. For example, CENTEREXE controls how far the centerlines và center marks extend beyond the objects and CENTERLAYER specifies the layer on which centerlines and center marks are created. You can also control the linetype và linetype scale used for centerlines và center marks, the kích cỡ of the central cross for center marks, và the extension line gap between the central cross và the extension lines of center marks.Once created, you can use grips khổng lồ easily adjust centerlines & center marks. And should the need arise, there are commands to disassociate centerlines and center marks from the objects they annotate, and lớn re-associate them with selected geometry.

Import PDF Geometry

The second big feature in AutoCAD 2017 is the ability lớn import geometry from a PDF tệp tin into lớn the current drawing as AutoCAD objects. AutoCAD has long had the ability lớn attach a PDF file as an underlay. You could then see the PDF file within the context of the drawing and create new geometry by snapping to the underlying PDF image.The new import PDF capability in AutoCAD 2017 goes well beyond this. After a PDF tệp tin is selected, an Import PDF dialog is displayed. You can then choose which page from the PDF file to import; specify its scale, rotation and insertion point; control what type of data is imported from the PDF tệp tin (geometry, solid fills, text, và raster objects); control how layers are assigned to lớn imported objects; & so on. Raster images are extracted from the PDF as PNG files and then attached lớn the drawing. Solid fills can be converted to hatches và other geometry is converted into polylines.

There are a few caveats, however. Geometry can only be imported if it was originally saved to lớn the PDF tệp tin as vector data. In other words, if the PDF was created by exporting from a CAD program, you will probably be able khổng lồ import the geometry, but if the PDF was created by scanning an old paper drawing, you’re out of luck. Also, the PDF file format does not recognize AutoCAD’s shape-based (SHX) fonts. When drawings with SHX are plotted to PDF, the text is stored as geometry. When you import the PDF file into AutoCAD, that text is added to the AutoCAD drawing as polylines, not text. But any text created using TrueType fonts will be imported as text objects.You can import a PDF file and immediately convert it inkhổng lồ AutoCAD objects, or convert a PDF tệp tin previously attached as an underlay.

Print Your Own 3D Models

3 chiều printing has really taken off and AutoCAD 2017 now offers two different methods for sending 3D models lớn a 3 chiều printer. You can choose “Send khổng lồ 3 chiều Print Service” lớn create an STL tệp tin that can then be sent khổng lồ a 3 chiều print service or cliông xã the new Print Studio tool, which downloads and installs Autodesk Print Studio, a separate application that enables you lớn print directly khổng lồ one of eight supported 3 chiều printers or save sầu a G-Code file for printing later.While there are other significant improvements in AutoCAD 2017, many of them are subtle changes made under the hood. For example, if you have a DirectX 11-capable graphics thẻ and have hardware acceleration enabled, you may notice a dramatic increase in performance. In previous release of AutoCAD, the preview image of objects being created, moved or copied could appear quite jagged. But in AutoCAD 2017, they appear just as smooth in this pReviews mode as once the creation or modification operation is completed.

In addition, linetypes with dash và dot combinations display round dots, whereas in previous releases these dots were represented by very short dashes. And when selecting objects that use complex linetypes, you can now select & snap to lớn objects even if you click in a blank space within the linetype.Because AutoCAD 2017 also takes advantage of the graphics processing unit (GPU) in most modern computers, complex linetypes are now generated by the GPU rather than the CPU, with graphics cached in GPU memory, significantly improving pan and zoom operations. AutoCAD’s underlying 3 chiều graphics subsystem has also been completely rewritten, resulting in faster performance with large 3D models and improved software stability.Other changes may be more obvious. For example, many of the program’s dialog boxes are larger. When you use a tệp tin dialog khổng lồ open or save a drawing, you may notice that the form size of the pĐánh Giá pane has increased. Other dialog boxes display more information, thus reducing scrolling. You can also resize many of these dialog boxes & AutoCAD will remember their kích cỡ the next time you use them.

New Companion Apps

When you first install AutoCAD 2017, you will likely also become aware of the new Autodesk desktop tiện ích that replaces the Autodesk Application Manager. This window is automatically displayed once the install is complete. A shortcut to lớn this new application also appears on the desktop và in the Windows Taskbar. This new companion application will be used khổng lồ deliver security patches and updates for all 2015, năm 2016 & 2017 versions of Autodesk’s Windows-based programs.

Whenever a hot fix, service patch or security patch becomes available, this program will display a notification on the system tray. When you launch the new companion application và open its update tab, you will see relevant details about the update & will be able to lớn click a button khổng lồ quickly & easily tải về and install the update on your computer.Autodesk has also improved the process of moving your custom settings from your previous version of AutoCAD khổng lồ AutoCAD 2017. A new Migrate Custom Settings tool provides a more intuitive interface that detects and clearly identifies customized settings, enabling you khổng lồ choose which ones you want lớn migrate.There are a host of other improvements as well. For example, the Coordination Model functionality has been enhanced lớn allow you lớn snap lớn precise locations on an attached coordination Mã Sản Phẩm using standard 2D endpoint và center object snaps. The A360 ribbon has also been updated to lớn support new functionality & to lớn remove sầu obsolete và less frequently used tools. For example, the AutoCAD 360 Web tool is no longer needed because you can edit online drawings by opening A360 Drive.

Design Feed is no longer displayed by default & its inhỏ has also been removed from the A360 ribbon. But AutoCAD 2017 offers a new tool that enables you khổng lồ easily publish views of drawings to lớn the cloud to facilitate collaboration with stakeholders while protecting your DWG files. When using the new Share Design View tool, your drawing is uploaded to a secure location in the cloud where 2D & 3 chiều views are extracted along with the property database. You can choose to lớn publish and display in your browser right away, or receive a notification on the Status Bar when all view processing is complete. Once you are satisfied with the kiến thiết view, you can nói qua a links with others who can then see the kiến thiết view in their browser for up khổng lồ 30 days without any logon requirements.With the exception of the 3 chiều printing tools, the same new features in AutoCAD 2017 are available in AutoCAD LT 2017 as well. Both programs began shipping in late March, with Design Suites khổng lồ follow in mid- lớn late-April. AutoCAD 2017 supports Windows 7, 8 and 10, và is available in both 32- and 64-bit versions. No announcement has been made regarding a new Macintosh release.There’s a lot lớn lượt thích about AutoCAD 2017 & likely more lớn come. Autodesk intends khổng lồ roll out new features periodically lớn all users. Since everyone using AutoCAD 2017 will be on subscription, there will be no more waiting a year khổng lồ see what’s new.
