Changes the property of the selected objects to ByLayer including color, linetype, lineweight, and materials.

Executes a command repetitively, avoiding press enter or space bar key.

Creates a new object of the same type and properties as selected object but with different geometric values.

Sets the display order of all the fill patterns to back position from all other objects.

Creates a section object that acts as a cutting plane through 3D objects and saves the selected section plane as a 2D or 3D block. You can move the section object dynamically in a 3D model or in a surface area. You can use the active section to analysis model by moving the section object in the object. Create cross-sectional views that can be saved or reused.

Converts one or a bunch of selected drawing files to another DWG version available. The newly generated file can overwrite the original file, and it can also be compressed into a self-extracting EXE file or a ZIP file to facilitate batch format conversion of the entire project drawing.

New CLIP command clips a block, external reference, image, viewport, and underlay (PDF or DGN) to a specified boundary. It can be used to replace XCLIP, IMAGECLIP, VPCLIP, PDFCLIP, DGNCLIP commands.

New array options are available to create copies of objects arranged in RECTANGULAR, POLAR, or PATH pattern. The new array object is a whole (dynamic block). It can be dynamically adjusted by number of objects, spacing and other related parameters through Ribbon panel and Multifunctional Grips.

Some hatch related system variables have been implemented: HPANNOTATIVE,  HPISLANDDETECTION,  HPMAXAREAS, HPORIGINSTOREASDEFAUL,  HPQUICKPREVTIMEOUT, HPLASTPATTERN HPLAYER, HPLINETYPE, HPPICKMODE, HPRELATIVEPS.

Now design center offers a quick way to update instances of block. Redefining a block allows you to overwrite each block instance without changing the block name, all while keeping the original block’s position. Alternatively, if you just copy a newer version of a block into your active drawing, the block will not update – it will instead inherent the active drawing’s block definition. By redefining a block, there is no need for deleting, purging, and copying.
