In this tutorial you will learn how to:
- Select objects using MYCADFUNS' 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 MYCADKEYS 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 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)
