# What's new in GstarCAD 2022 [GstarCAD 2023](Help%20System/GSTARCAD/2023/Index.md) → [What's new](Help%20System/GSTARCAD/2023/What's%20new/(What's%20new).md) In GstarCAD 2022, we significantly improved the performance of plotting system, making plotting effects more precise and accurate. we restructured the  Raster Engine and added support for hundreds of raster image formats. In this engine, 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, we are committed to improve product quality and user experience. GstarCAD 2022 has improved performance in terms of layers, dimensions, trimming and group, and studied many innovative functions such as LAYULKALL, CHANGEBASE, LAYDRAWORDER and GROUPEDIT. ## **[Plotting Improvement](NewFunction2022_Plottingimprovment.md)** We restructured the printing system in GstarCAD 2022, focusing on enhancing PDF printing driver, plotting with transparency and ordinary hidden shade plotting to obtain more accurate text, super-large images and curved printing effects. At the same time, we also fixed a large number of problems in the last version.  ### 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**](NewFunction2022_rasterimageimprovment.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](NewFunction2022_drawingdisplayimprovment.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](NewFunction2022_dimensionimprovment.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](NewFunction2022_multilinetrimming.md)** The multiline can be easily trimmed or extended by various objects like lines, polylines, circles, arcs, ellipses, splines, etc. ## **[3、GROUP Improvement](NewFunction2022_GROUPImprovement.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](NewFunction2022_LAYULKALL.md) Based on user needs, the LAYULKALLY function is developed in GstarCAD 2022. The function can unlock all the locked layers immediately, instead of unlocking them one by one. ## [2、CHANGEBASE](NewFunction2022_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/2023/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.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)](SDI.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. --- [Original help](https://www.gstarcad.net/help/GstarCAD_2023_en-US/detail/GstarCAD2023NEW/NewFunction2022.html) · © Gstarsoft Co., Ltd.
