# 2D Geometry

The 2D Layout for 3D Design workbench enables you to create 2D geometry.

 As 2D geometry commands work exactly as in the Sketcher workbench, this section of the documentation actually provides links to the Sketcher User's Guide. As such, the information detailed in this section is presented in a Sketcher context. You should note that the Sketcher User's Guide contains images that correspond to the Sketcher workbench and therefore illustrate geometry in an environment that is different from the 2D Layout for 3D Design environment (symbols and background color, for example).

Before You Begin Creating 2D Geometry in 2D Layout for 3D Design: You should be familiar with important concepts.

 Create a profile: Use the Tools Palette or click to define lines and arcs. Create a rectangle: Use the Tools Palette or click the rectangle vertices one after the other. Create an oriented rectangle: Use the Tools Palette or click to define a first side for the rectangle and then a point corresponding to the rectangle length. Create a parallelogram: Use the Tools Palette or click to define a first side for the parallelogram and then a point corresponding to the parallelogram length. Create an elongated hole: Use the Tools Palette or click to define the center to center axis and then a point corresponding to the curved oblong profile length and angle. Create a cylindrical elongated hole: Use the Tools Palette or click to define the center to center circular axis and then a point corresponding to the curved oblong profile length and angle. Create a keyhole profile: Use the Tools Palette or click to define the center to center axis and then two points corresponding to both radii. Create an hexagon: Use the Tools Palette or click to define the hexagon center and dimension. Create centered rectangles: Use the Tools Palette to define the rectangle center and dimensions. Create centered parallelograms: Use the Tools Palette to define a first side for the parallelogram and then a point corresponding to the parallelogram length. Create a circle: Use the Tools Palette or click to define the circle center and then one point on the circle. Create a three point circle: Use the Tools Palette or click to define the circle start point, second point and end point one after the other. Create a circle using coordinates: Use the Circle Definition dialog box to define the circle center point and radius. Create a tri-tangent circle: Click three elements one after the other to create a circle made of three tangent constraints. Create a three point arc: Use the Tools Palette or click to define the arc start point, end point and second point one after the other. Create a three point arc with limits: Use the Tools Palette or click to define the arc start point, end point and second point one after the other. Create an arc: Use the Tools Palette or click to define the arc center, then the arc start point and end point. Create a spline: Click the points through which the spline will go. Connect curves with a spline: Click the first, then the second element to connect. Create an ellipse: Use the Tools Palette or click to define the ellipse center, major semi-axis and minor semi-axis endpoints one after the other. Create a parabola by focus: Click the focus, apex then the two extremity points. Create a hyperbola by focus: Click the focus, center and apex, then the two extremity points. Create a conic: Click the desired points and eccentricity for creating an ellipse, a circle, a parabola or a hyperbola, using tangents, if needed. Create a line: Use the Tools Palette or click the first and second points of the line. Create an infinite line: Use the Profile toolbar or click the first and second points of the infinite line. Create a bi-tangent line: Click two elements one after the other to create a line that is tangent to these two elements. Create a bisecting line: Click two lines. Create a line normal to a curve: Click a point and then the curve. Create a point: Use the Tools Palette or select the point horizontal and vertical coordinates. Create a points using coordinates: Enter in the Point Definition dialog box cartesian or polar coordinates. Create an equidistant point: Enter in the Equidistant Point Definition dialog box the number and spacing of the points to be equidistantly created on a line or a curve-type element. Create a point using intersection: Create one or more points by intersecting curve type elements. Create a point using projection: Create one or more points by projecting points onto curve type elements.
