The Drawing Tools allow you to create a survey by drawing points, polylines, or boundaries that describe topographic features like natural ground, stockpiles, breaklines, roads, or when drawing planimetric features like building outlines, manholes, parking lines/islands, etc. You can use these drawn geometries to create a topographic surface and export them to CAD. The drawing tools are available in the Drawing group of the HOME tab or can be found in the mini toolbar by using right click in the Viewport.

Drawing Tools Overview
Virtual Surveyor offers multiple drawing tools to help you describe a topographic surface. The Polyline tool, and its specialized Arc tool, are great for drawing breaklines and lines. The Boundary tool and its specialized versions (Circle and Rectangle) are grouped in another dropdown menu and are great for delineating survey areas or drawing shapes for planimetric or design surveys. Each tool is specialized in how they capture everything from stockpiles and terrain features, to paint lines and manholes, each helping you identify and describe a survey feature in the way that best describes them.
Each tool, except Point and Arc, has an input selection option that changes how you can draw the line or boundary in order to make your job easier. The drawing tool you are using stays enabled (highlighted in the ribbon) until you disable it by right-clicking anywhere in the Viewport, or by clicking on the icon again to disable it.
Switch between drawing tools. You can quickly switch from Point, Polyline, and Boundary drawing tools by left-clicking the respective button in the Home tab menu. You can also click on the arrow below the Polyline and Boundary tool icons to quickly switch to and enable the Arc, Circle, and Rectangle tools from the dropdown menu options.

Point Tool
The Point tool draws a vertex at ground level on the terrain with each click.
- Enable the Point drawing mode in the HOME tab.
- Left-click in the Viewport to add points.

Polyline Tool
The Polyline tool can be used to draw breaklines for slopes, road marking lines, parking lines, etc., and any other terrestrial feature that can be described by a line. All lines by default are drawn on the terrain. The Virtual Surveyor app gives you multiple input options for the Polyline tool to be able to draw any terrestrial feature for survey grade information.
How the Polyline tool works:
- Enable the Polyline tool in the HOME tab.
- Choose an input selection of the Polyline for the Line Drawing Mode.
- Left-click in the Viewport to add polyline vertices.
- Right-click to finalize your polyline.
Input selection options:
- Free: allows you to freely draw a line in any direction.

- Arc: draws a curved polyline in tangent to your most recently drawn line segment. You can switch between Free and Arc line drawing modes to apply an arc to a specific part of the polyline. This is useful when you are drawing a continuous line (e.g., a road or breakline) and need to insert a curve without starting a new line.

- Guided Breakline: draws a line that follows a break in a slope based on the distance between the first placed vertex and the second, as well as the direction you point it when following a break in a slope. You can quickly switch between Free and Arc modes to help draw lines over areas that require human input.
Arc Tool
The Arc tool is a special type of polyline that draws a symmetrical pathway for a rounded corner. This tool works differently from the tangent you get when using the Polyline tool with the Arc drawing mode.
- Enable the Arc tool in the HOME tab (Polyline dropdown menu).
- Draw an arc on a rounded corner using three clicks:
- First click = arc starting point.
- Second click = arc ending point.
- Third click = arc radius and completes the arc.

Boundary Tool
The Boundary tool is a versatile tool for creating areas you want to survey within, making shapes for planimetric drawings, and for outlining stockpiles, to name a few. All boundary tool vertices are placed at the elevation of the terrain, same as the Polyline tool.
- Enable the Boundary tool in the HOME tab.
- Select the Line Drawing Mode:
- Free: draws regular straight lines from vertex to vertex to create your boundary shape manually.
- Arc: draws a curved boundary line in tangent to your most recently drawn line segment. You can switch between the Free and Arc line drawing modes to apply the arc to a specified part of the boundary. This is useful when you are drawing a complex outline and need to insert a curve on part of the boundary line.
- Guided Breakline: draws a line that follows a break in a slope based on the distance between the first placed vertex and the second, as well as the direction you point it when following a break in a slope. You can quickly switch between Free and Arc modes to help draw lines over areas that require human input.
- Left click in the Viewport to draw the boundary vertices.
- Right-click to finalize the boundary.

Circle Tool
The Circle tool can be used for planimetric surveys or for outlining areas to create a topographic design.
Edge First: draws a circle by starting at the edge of a circular feature and drawing across the circular object.
- Enable Circle drawing mode in the HOME tab (Boundary drop-down menu).
- Draw the circle; each circle is defined by 2 clicks:
- First click = point on the circle perimeter.
- Second click = another point at the diameter from the first click to complete the circle.

Center First: a design feature that draws a circle from a center starting point, outward. (Only available with a Peak license.)
- Enable the Circle drawing mode in the HOME tab (using the Boundary tool drop-down menu).
- Draw the circle; each circle is defined by 2 clicks:
- First click = point on the center of a circular.
- Second click = another point at the radius of the first click to complete the circle.

Rectangle Tool
The Rectangle tool, like the circle tool, can be used for planimetric surveys and topographic survey areas, as well as drawing building outlines.
Side First: The Side First mode is an intuitive way to quickly draw a rectangle for a terrain feature. It is helpful to orient the terrain to get the appropriate rectangle angle and shape.
- Enable Rectangle drawing mode in the HOME tab.
- Ensure Side First mode is selected.
- Draw the rectangle; each rectangle is defined by 3 clicks:
- First click = first corner of the rectangle.
- Second click = opposite of the first selected rectangle corner.
- Third click = draw straight across to the third rectangle corner and left click to complete the rectangle.

Diagonal First: The Diagonal first mode is most effective at aligning rectangles to be symmetrical no matter the orientation of your view in the Viewport.
- Enable Rectangle drawing mode in the HOME tab (Boundary drop-down menu).
- Select the Diagonal First drawing mode.
- Draw the rectangle; each rectangle is defined by 3 clicks:
- First click = first corner of the rectangle.
- Second click = opposite of the first selected rectangle corner.
- Third click = draw to the third rectangle corner and left click to complete the rectangle.

Drawing Guides
The drawing guides give you measurements on the terrain that you can choose to snap to in order to help you keep a—more or less—consistent distance between vertices on a polyline/boundary and/or keep a true direction.
Distance Guide
The Distance guide, when enabled, gives you a fixed radius around the previously placed point at a user defined distance. This is useful for design, breakline measurements, and just about any other geometric drawing you want to create a—more or less—equal distance between vertices. 
Angle Guide
The Angle guide, when enabled—allows user defined angles at a degree—gives you a true heading from the direction of the previously placed line segment. It is useful for design, building outlines, and following long distance pathways along roads, a few examples.

Geometry Snapping with Drawing Tools
The Geometry Snapping feature allows you to accurately connect existing geometry together. When drawing a geometry using any of the Drawing Modes, geometry snapping is enabled by default.
How snapping works. When enabled, Geometry Snapping always takes preference when drawing points or geometries. E.g. a purple circle will appear on any geometry that is in your drawing path, and your vertex will first snap to the nearby geometry rather than place itself on the terrain. Simply left click when the purple circle or dot appears to snap to that existing vertex or geometry.

Disable Snapping While Drawing
Snapping is designed to streamline your workflow and make it easier to connect drawings and create clean surfaces, but you can switch to free placement whenever necessary by disabling geometry snapping:
- Deselect the Geometry snapping box with a left click.
- Use the hot key "G" on the keyboard to toggle snapping on and off.
- Press and hold Ctrl to temporarily disable snapping when drawing a polyline or point over other geometric drawings.

Project Examples for Using Drawing Tools
- Topographic survey of a natural area: Use the drawing tools to create a surface on your drone data and export the surface as CAD files.

- Curb and gutter: Combine the Offset Line and Move/Copy tools with the Polyline and Arc tools for tracing curbs and gutters.

- Line survey in a quarry: Use the Polyline tool to draw breaklines. Polylines are usually required for mine surveys and are very useful for creating a Triangulated Irregular Network (TIN).

- Planimetric survey: Use Polyline and Boundary tools along with Move/Copy to significantly speed up the creation of comprehensive planimetric surveys.

Tips and Tricks
- You can always edit your drawn or imported lines via the TOOLS tab when drawn data is selected.
- Click on the Edit Vertex button in the TOOLS tab to begin your edit modes.
- You can merge any two (or more) polylines together to create a single polyline. E.g., when you have a line drawn with the Polyline tool and another line that meets up with it drawn separately by the Arc tool.
- Use Move/Copy tool on drawn geometries to move, duplicate, align, and rotate them quickly and efficiently for planimetric drawings.
- Use Extend/Trim line editing tools in conjunction with the drawing tools to quickly create exact representations of planimetric drawings or building outlines.
- You can edit the vertices of drawn geometries to manually place them all at the same elevation on the Elevation Terrain.
- Draw the geometry with one of the tools described in this article.
- Select the object and enable the Edit Vertex tool in the TOOLS tab.
- Set the Edit Vertex Mode to Z.
- Select each vertex to edit using Ctrl+Left-click and manually set the Z value in the vertex coordinates box.
