AutoCAD edit Multi-line Object

For multi-line objects, you can add or remove vertices by using the "Mledit" command, and multiple methods are used to construct a multi-line intersection.

7.7.1 Instance 3 edit multi-line

Step 1 Open a graphics file

Start the AutoCAD 2002 system to open the instance file "EXAM6-4.DWG" created in chapter 6th;

Step 2 Hide Guides

Create a layer named "Xline" and change the layer of all guides to "xline" and then close the layer.

Step 3 Edit Multi-line

Select Menu "Modify (Modify)" → "Object (object)" → "Multiline ... (multi-line), the system will pop up the Multiline Edit Tools dialog box, as shown in Figure 7-14.

The user can click the Image control in the dialog box, and the description is displayed at the bottom of the dialog box. Select the merged Tee (T-merge) item and click the OK button to exit the dialog box and do the following:

Command: _mledit
Select the Mline:	Select a multi-line (equivalent to a vertical line of "T") that intersects a "T" shape
Select Second Mline:	Select another multi-line (equivalent to the horizontal section of "T") that intersects with it
Select the Mline or [Undo]:	Continuous entry as above operation

When all the "T" connections were modified, we finished all the drawing work and the final result was shown in Figure 7-15.

Step 4 Save the file

Save the changes you made above.

Example description

The multi-line edit command is invoked in the following way:

Toolbar: "Modify II (Modified II)" →

Menu: "Modify (Modify)" → "Object (object)" → "Multiline ... (Multi-line) "

Command line: Mledit

Call the command line, pops up the Multiline Edit Tools dialog box, which provides 12 modification tools for working with crossed multi-line (first column), T-shaped multi-line (second column), Corner-point binding and Vertex (third column), Handles multiple-line cut or splice (fourth column). The following are described separately:

(1) "Closed Cross (Cross closure)": Create a closed cross between two lines.

(2) "Open Cross (Cross)": Create an open cross between two lines. AutoCAD interrupts all elements of the first multi-line and the outer elements of the second multi-line.

(3) "Merged Cross (Cross)": Create a merged cross between two lines, and the result is independent of the selection order of multiple lines.

(4) "Close Tee" (t-shape closure): Creates a closed T-cross between two lines. AutoCAD trims the first multi-line or extends it to the intersection with the second line of multiple lines.

(5) "Open Tee (T-shaped)": Create an open T-cross between two lines. AutoCAD trims the first multi-line or extends it to the intersection with the second line of multiple lines.

(6) "Merged Tee (T-shaped)": Create a merged T-cross between two lines. AutoCAD trims the first multi-line or extends it to the intersection with the second line of multiple lines.

(7) "Corner Joint (corner-point combination)": Create a corner-point combination between two lines. AutoCAD trims the first multi-line or extends it to the intersection with the second line of multiple lines.

(8) "Add Vertex": Adds a vertex to the multi-line.

(9) "Delete Vertex (delete vertex)": Deletes a vertex from multiple lines.

(Ten) "Cut single": Cuts selected elements on multiple lines.

(one) "Cut all": cuts all the elements on multiple lines and divides them into two parts.

(a) "Weld all (Join All)": Reconnect a multi-line segment that has been cut.

Summary

This chapter describes how to edit a graphic by using pinch points and grouping, making editing more flexible.

The select set can be filtered using the Quick selection and object filters to remove objects that do not meet the filter criteria.

When multiple drawing objects overlap, the user can change the display and print order between them.

In addition, for filling patterns, multi-line lines, spline curves and multi-line objects, AutoCAD provides the corresponding editing commands to modify.
