Join 3d polylines autocad lisp?

If you want to join a 3D polyline with another one, or with a spline, you can use the command JOIN. This function joins also two or more 3D polylines into one, or joins a 3D polyline with a spline to a new spline curve. You can use JOIN for 3D lines (geometry) also in AutoCAD LT.

Also the question is, how do I join multiple polylines in AutoCAD?

1. Click Home tab Modify panel Edit Polyline. Find.
2. Select a polyline, spline, line, or arc to edit.
3. Enter j (Join).
4. Select one or more polylines, splines, lines, or arcs that are located end to end.
5. Press Enter to end the command.

Use the Join command to join connecting feature lines, polylines, or 3D polylines into one feature line or survey figure. Select the two lines. They are joined if they lie within the tolerance distance set in JoinFeatures command settings. Click Modify tab Edit Geometry panel Join .

How do you break a feature line?

1. Click Modify tab Edit Geometry panel Break Find.
2. Select the feature line to break:
3. Specify the second break point. Note: if you enter the @ character at the prompt for the second break point, it uses the first point location, creating a break without a gap.

Why is join not working in AutoCAD?

What is Pedit in AutoCAD?

Common uses for PEDIT include joining 2D polylines, converting lines and arcs into 2D polylines, and converting polylines into curves that approximate B-splines (spline-fit polylines). Different prompts are displayed, depending on the type of object you select to edit.

How do I connect lines in AutoCAD?

What is JOIN command in AutoCAD?

The Join command in AutoCAD is used to join the objects end to end to create a single object. The objects can be curved or linear, depending on the requirements. It combines the series of linear and curved to create a single 2D or 3D object.

How do you merge in AutoCAD?

2. Click the Layout tab and then click the arrow next to the Insert group.
3. Click Import Drawing/Data. The Open dialog box opens.
4. Select the source file to merge into the current drawing.
5. Select additional source files to be merged, one at a time, to add additional sheets to the current drawing.

What occurs if two feature lines occupy the same site and intersect?

This means that Feature Lines will interact with other Feature Lines that are included in the same Site. (If you don’t want them to interact with each other put them in different Sites.) So, if you create two Feature Lines that cross each other a Split Point will be created at the intersecting location.

How do you trim a feature line in Civil 3D?

2. Select the objects to serve as cutting edges.
3. Select the feature line(s) to trim.

What is a feature line?

So that’s what Feature Lines do, they represent edges or linear objects in a three dimensional form in your drawing model. In fact, if you’re familiar with AutoCAD 3D polylines in a fundamental sense they’re very similar.
