# What's new in GstarCAD 2022 [GstarCAD 2022](Help%20System/GSTARCAD/2022/Index.md) → [What's new](Help%20System/GSTARCAD/2022/What's%20new/(What's%20new).md) In GstarCAD 2022, the plot functionalities are significantly improved, making plotting effects more precise and accurate. An upgraded raster engine has been integrated and enables more image formats, even 1 billion pixels images can be correctly attached, previewed, modified and plotted. Beyond, GstarCAD 2022 offers a plethora of other new and improved tools to help maximize your productivity. In addition, many functions and development interfaces such as layers, dimensions, trimming and group are improved, and innovative functions such as LAYULKALL, CHANGEBASE, LAYDRAWORDER and GROUPEDIT are developed, which comprehensively improve the product quality and user experience. ## **[Plotting Improvement](Help%20System/GSTARCAD/2022/What's%20new/Plotting%20Improvement.md)** The plotting system is reconstructed in GstarCAD 2022, focusing on the improvement of PDF plotting driver, plotting with transparency and traditional hidden shade plotting. The plotting effect of texts, super large images and curves is more fine and accurate. At the same time, a large number of problems in the old version are fixed. ### 1、**PDF Plotting Driver** After optimizing the PDF plotting driver, the TrueType fonts are plotted as searchable texts. Hyperlinks are retained and remain clickable when you plot to PDF. And third-party tools can easily read all information of the PDF plotted from GstarCAD 2022\. ### 2、**Plotting with Transparency** Except for the gradient hatch with transparency, solid hatches and other objects are all plotted as vectors, the arcs, circles, ellipses, graphics and text boundaries are smoother. And the drawing information after plotted will not be modified, all kinds of objects can be plotted correctly. ### 3、**Hidden Shade Plotting** Objects are plotted as vectors with the Legacy hidden option, making the display of plotted files much better. ### 4、**Raster Images Plotting** Large raster images plotting performance is improved, images are outputted after being processed, so the output data are much smaller in size. Issues like images disappearing and position changing after modification are solved. ## [**Raster Images Improvement**](Help%20System/GSTARCAD/2022/What's%20new/Raster%20Images%20Improvement.md) There are more raster image formats supported in GstarCAD 2022\. The display, the effect after modifying and the speed are also greatly improved when processing large raster images. The effects of brightness, contrast, fade, and highlight modification are more accurate. ## [Drawing Display Improvement](Help%20System/GSTARCAD/2022/What's%20new/Drawing%20Display%20Improvement.md) **1、LINESMOOTHING** Without anti-aliasing, the inclined lines and curved lines appear jagged, like staircases. When anti-aliasing applied, the jagged effect is eliminated and the graphic are displayed more smoothly. You can also switch the anti-aliasing effect by setting the LINESMOOTHING system variable. **2、Automatic Regeneration** The drawing is always automatically regenerated when you zoom or pan, that makes operation process smoother and display better. ## General Functions Improvement ## **[1、Dimension Improvement](Help%20System/GSTARCAD/2022/What's%20new/Dimension%20Improvement.md)** The DIMREASSOCIATE, DIMREGEN, DIMCENTER, Stretch Dimension Group commands and the DIMLAYER and DIMTOFFSET system variables are supported to make the dimension display more reasonable and accurate, and make it easier and faster to modify dimensions. ## **[2、Multiline Trimming](Help%20System/GSTARCAD/2022/What's%20new/Multiline%20Trimming.md)** The multiline can be easily trimmed or extended by various objects like lines, polylines, circles, arcs, ellipses, splines, etc. ## **[3、GROUP Improvement](Help%20System/GSTARCAD/2022/What's%20new/GROUP%20Improvement.md)** Most group commands are organized into a Groups Panel in the ribbon, making it more convenient to create groups, edit groups, ungroup and control the group display by clicking icons in the ribbon directly. ## New Functions ## [1、LAYULKALL](LAYULKALL.md) You can use the LAYULKALL command to unlock all the locked layers immediately, instead of unlocking them one by one. ## [2、CHANGEBASE](CHANGEBASE.md) The CHANGEBASE command allows changing the base point position of a block. You can move the base point and keep objects staying in the original position, or move objects and keep the base point staying in the original position. ## [3、LAYDRAWORDER](Help%20System/GSTARCAD/2022/What's%20new/LAYDRAWORDER.md) The LAYDRAWORDER command allows rearranging the layers. You are able to select one or more layers, and bring them to front or send them to back with buttons in "Layer Draw Order" dialog box. You can also change the order of the layers in "Layers to Adjust Draw Order" list conveniently. ## [4、FASTSEL/FS](FASTSEL-FS.md) The FASTSEL/FS command allows selecting all the objects that touch the selected object, including lines, polylines, circles, arcs, texts, Mtexts, ellipses. The FSMODE command controls two different behavior of the FASTSEL/FS command. ## [5、SDI (Single Document Interface)](Help%20System/GSTARCAD/2022/What's%20new/SDI%20(Single%20Document%20Interface).md) The SDI system variable is used to control the program running on a single file interface or multiple file interfaces. The SDI system variable can not be reset to 1 when multiple documents are already opened in the software. ## Add ACET extension interface Support for more than 300 ACET interfaces is added to improve the compatibility of LISP interfaces. Some LISP programs that rely on ACET extension interfaces can be loaded and run directly in GstarCAD 2022\. Want to know the Highlighted Features in GstarCAD 2021?
