The appearance of the centerlines and center marks are controlled by a number of new system variables. The new Center Mark and Centerline tools appear prominently on the Annotate ribbon.
Once created, if you modify the associated objects, the centerlines and center marks update accordingly. The new Center Mark tool creates an associative center mark at the center of a selected circle, arc or polygonal arc. The Centerline tool creates centerline geometry of a specified linetype that remains associated with the selected lines and polylines. Associative Centerlines and Center MarksĪutoCAD 2017 introduces powerful new tools for creating and editing centerlines and center marks and these new tools appear prominently on the Annotate ribbon. With AutoCAD 2017, that situation has finally changed. As a result, centerlines and center marks continued to consist of lines that once drawn were entirely unrelated to the geometry they were used to annotate. Those objects remained largely unchanged from when they were first introduced more than 20 years ago. But last year’s improvements did not include centerlines or center marks. You could also place all those dimensions on a specified layer rather than having to first make the appropriate layer the current layer. For the first time, you could create multiple types of associative dimensions without having to end one command and start another. AutoCAD 2016 introduced an entirely new tool for creating all types of dimensions using a single command. In fact, there are three really big changes, and the first two involve dimensioning - sort of. That is not to say that there aren’t some very significant enhancements in AutoCAD 2017. As such, a lot of the effort in this release was done behind the scenes to smooth this transition.
The new version sets the stage for Autodesk’s move away from a perpetual license model (in which you own a copy of a particular release of AutoCAD and can use it essentially forever) and to a subscription model in which customers rent the software on a monthly, quarterly, annual or multi-year basis. I n late March, Autodesk unveiled AutoCAD 2017, the 31st release of its flagship product.
