As many you asked, how do you intersect **two** **lines**?

- First we need the equations of the two
**lines**. - Then, since at the point of intersection, the two equations will have the same values of x and y, we set the
**two**equations equal to each other.

Considering this, why won’t my lines join in **AutoCAD**? Causes: Objects have gaps or do not have connecting points because of different elevations. Use the UNITS command and increase the precision to maximum. Examining the lines, the Properties palette will show Start Z / End Z or Elevation values, potentially of a minute amount.

Amazingly, how do I turn on intersection in AutoCAD? **Make** sure intersection is active in the object snap menu and then activate any Draw command. Now move your cursor close to the point of intersection of any two objects, a green X marker will show up which is the intersection snap marker. As long as the marker is visible the cursor will snap to the intersection point.

Subsequently, how do I close **two** lines in AutoCAD?

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

If f = 0 for any point, then the two **lines** touch at a point. If f1_1 and f1_2 are equal or f2_1 and f2_2 are equal, then the lines do not intersect. If f1_1 and f1_2 are unequal and f2_1 and f2_2 are unequal, then the line segments intersect.

## What is the formula for point of intersection?

Point of intersection means the point at which two lines intersect. These two lines are represented by the equation a1x + b1y + c1= 0 and a2x + b2y + c2 = 0, respectively.

## How do you join objects in AutoCAD?

- Click Home tab Modify panel Join. Find.
- Select a source object or select multiple objects to join together.
- Valid objects include lines, arcs, elliptical arcs, polylines, 3D polylines, and splines.

## What is Pedit command in AutoCAD?

Edits polylines, objects to be joined to polylines, and related objects. Find. 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).

## How do you fillet in AutoCAD?

- Select the Fillet command from the ribbon panel. Or.
- Type M or Multiple on the command line.
- Press Enter.
- Select the first object.
- Type R or Radius on the command line.
- Press Enter.
- Specify the fillet radius. For example, 1.
- Press Enter.

## How do you join two perpendicular lines in AutoCAD?

- Type “ Join” in command section.
- Select the lines to be joined and press enter. That’s it.

## What is Ortho mode in AutoCAD?

The Ortho mode in AutoCAD is used to restrict cursor movement to specific directions. It allows the cursor movement only in the vertical and horizontal direction. When we create, modify, or move the drawings, the ORTHO mode is used to restrict the movement relative to the UCS (User Coordinate System).

## What is the union command in AutoCAD?

The Union command is used to combine the selected 2D regions or 3D solids by the addition. The selected parts are combined to form a single region, surface, or solid.

## How do I fix gaps in AutoCAD?

## Can different polylines be joined together?

yes the correct answer is yes option A.
