In this tutorial you will learn how to:

  • Select objects using ACDUI’s extended range of Select Objects options,

User entries are in bold text.

Prompts are in italic text.

Open or create a simple drawing containing a variety of objects on a range of layers.  You will need some Blocks, with multiple copies of at least one of them.

Create a bunch of new objects by exploding one of the blocks.

Start ACADUI E - Erase command:

Command: E <enter>

Note the two lines of reminder prompt:

Select objects options:  =byproperty/*everything/All/Block/Crossing/Dialogue/Entlast/Fen/Grp/Just-bfr-last/ Last/New/Over(WP)/Prev/Under(CP)/Visible/Window/eXcl

Compare this with AutoCAD’s options and note the extra options: =byproperty, *everything, Block, Dialogue, Entlast, Just-before-last, New.

AutoCAD’s Object/Subobject is not yet implemented.

And the main prompt:

ADD mode…+/-?/ALTMENU/<[done]>/<<add/remove>>….Select objects:

The prompt will change from ADD to REMOVE if – is pressed and vice-versa.

Left or right clicks and drags add or remove respectively but do not change the ADD REMOVE mode i.e. selection stays in the ADD mode unless deliberately changed to REMOVE.

<enter> or [spacebar] will terminate the command and will prompt:

Total selected: n:    (n is the number selected).

If you have a four line Command: area you also will see a reminder on the top line

Use ED to Erase Duplicate objects:

Experiment with each of the options have fun.

Try the Erase = Layer option:

*/<<use/check>>/type-it/[dialogue]/<0>

<<use a left pick to select a layer to erase all objects with that layer name.  A right pick check>> invites you to check the results of a layer pick then reports the layer name and invites you to [accept] or AOK to try-again.

Selected layer: mylayer  [accept]/AOK-try again 

 (AOK = Any Other Key)
