The TRIM command can be used to clean up overhanging entities over a boundary. Its companion command, EXTEND enables entities to be extended to a boundary.
TRIM command
To start the command and trim an entity object, do one of the following:
Choose Trim from the Modify drop down menu.
On the modify toolbar, click the Trim tool.
Type TRIM in the command line and then press ENTER
Operation
The first prompt asks for the user to select the boundary edge (the entity that will be used for the cutting edge).
When the boundary has been selected, hit the right mouse button.
The next object selected is the piece of the entity that needs to be removed. The cut is then effected.
Here we cover the use of some important editing tools in the gCADPlus drawing environment – Trim, Extend, and Fillet.
Extend command
To start the command and extend an entity object, do one of the following:
Choose Extend from the Modify drop down menu.
On the modify toolbar, click the Extend tool.
Type EXTEND in the command line and then press ENTER
The first prompt asks for the boundary to which the entity is to be extended, right click the mouse button after selection, then choose the entity to extend.
There are times when these commands seem to fail. Here we show that sometimes small errors in the construction of the design can be the reason.
