Once you are done, your lines start and end precisely on what is already drawn, and a new line can follow fixed angles.

## Snap to a point

1. Start a tool that needs a point, for example **3D Polyline** on the toolbar.

2. Move the mouse over a line in the drawing. A red marker shows where VCAD snaps, and its shape shows what it snaps to. At the bottom, to the right of the message line, **X**, **Y** and **Z** turn blue and show the point's coordinates and elevation.

    > If no red marker appears, snap is off. Click **Snap** on the toolbar.

3. Click while the marker is there. The point lands exactly on the marker.

## Choose what it snaps to

1. Right-click **Snap**, the button with the magnet on the toolbar.

    ![The whole toolbar with the list under Snap open: ticks at Endpoint, Midpoint, Center, Perpendicular, Intersection and Nearest, each with its marker, and below them Angle Lock with 15° and None. Snap and the list are ringed](https://vcad.dk/help/snap-to-points/snap-menu-en.png)

2. Click what you want to turn on or off.

3. To snap to one of them only, click **None** first and then the one you want.

| In the list | Snaps to | The marker |
| --- | --- | --- |
| **Endpoint** | the ends and the vertices of a line | ![A red square](https://vcad.dk/help/snap-to-points/marker-endpoint.png) |
| **Midpoint** | the middle of a line segment | ![A red triangle](https://vcad.dk/help/snap-to-points/marker-midpoint.png) |
| **Center** | the center of a circle and a survey point | ![A red circle](https://vcad.dk/help/snap-to-points/marker-center.png) |
| **Perpendicular** | the spot on a line where the new line meets it at a right angle | ![A red T](https://vcad.dk/help/snap-to-points/marker-perpendicular.png) |
| **Intersection** | the spot where two lines cross | ![A red plus sign](https://vcad.dk/help/snap-to-points/marker-intersection.png) |
| **Nearest** | the spot on a line nearest the mouse | ![A red diamond](https://vcad.dk/help/snap-to-points/marker-nearest.png) |

## Turn snap off and on again

1. Click **Snap** on the toolbar, or press **F3**. The magnet is crossed out.

    ![The whole toolbar just after a click on Snap: the magnet is crossed out, and Snap is ringed](https://vcad.dk/help/snap-to-points/snap-off-en.png)

2. Click **Snap** again, or press **F3**.

## Lock the angle

1. Right-click **Snap**.

2. Click **Angle Lock**.

3. Click the number to the right of **Angle Lock** until it shows the angle you want. The number switches between 15°, 30° and 45°.

4. Start a tool that draws lines, for example **3D Polyline** on the toolbar or a line in one of the palettes.

5. Click the first point in the drawing. Guide lines run out from the point for every angle.

    > If no guide lines appear, snap is off. Angle lock only works when snap is on.

6. Move the mouse close to a guide line. The line follows it, and the guide line lights up.

    ![Guide lines run out every 15° from the end of a kerb line, and the new line follows the 30° guide line, which lights up. The new line is ringed, and its length shows next to the mouse](https://vcad.dk/help/snap-to-points/angle-lock.png)

The angles are counted from the previous line segment, and the first segment is counted from the horizontal.

## If something doesn't work

| What you see | What to do |
| --- | --- |
| No red marker appears, even though snap is on | What you want to snap to has no tick. Right-click **Snap** and click it. |
| Snap only catches when the mouse is very close | Make **Snap range (px)** larger. You find it in the account menu under **Settings**, the **Snap tuning** tab. |
| F3 does not turn snap on or off | The cursor is in a field, or you are in the middle of a line: click **Snap** on the toolbar instead. A list is open: press **Esc** to close it, and press **F3** again. |
