3 SNAP MODES When using the CAD functions within NC Express the majority of functions require that a Snap Mode be utilized in order to carry out the function and be precise with the placement of the point. For every function that is selected there is a ‘point’ that is needed to be selected. On the bottom coordinate section of NC Express (shown below) you will see on the left side which function is currently active, then X and Y coordinates, and towards the right side you will find what type of selection the CAD is looking for (ex. First Point, Element, Centre, etc…). For example, when a two point line is selected as the function CAD will ask for the ‘First Point’ and once clicked it will then ask for the ‘Second Point’ to finish the line. During this process a Snap Mode (Point) will be needed in order to make the ‘First Point’ and ‘Second Point’. On the right side of the drawing window you will find all of the Snap Modes listed. Each Snap Mode can be selected by clicking the Mode within the toolbar or by using the keyboard shortcut keys. Each shortcut key is listed along with a description of the Snap Mode within the next few pages. 3.1 Snap Modes Described Below are descriptions along with an example of how to use each of the Snap Modes. CURRENT- The last point drawn (current point), typically the end point of a line or an arc. Can be used when connecting a line and a line or arc and a line. HOW TO USE- If a Line 2 Points has been drawn, for example, and an Arc will be needed at the end of the line, after selecting the Arc type select Current as the Snap Mode and the last point of the line segment will be the ‘First Point’ of the Arc. SHORTCUT KEY: U FREE POINT- Allows for a selection anywhere within the drawing area. Automatic snap to end of a segment is deactivated with this Snap Mode active. This Snap Mode would typically be used in conjunction with placement of a construction line or if precision placement is not needed. 18
HOW TO USE- Select Line 2 Point, for example, then select Free Point and click anywhere within the drawing area. Select Free Point again and click anywhere within the drawing area. The line will be placed between the two selected points. SHORTCUT KEY: F END POINT- On the given line segment, End Point uses the closest end point from the point of where the cursor was clicked. NOTE- This Snap Mode is primarily always activated even if it is not selected. HOW TO USE- To create an arc on a line segment, select Arc- Semicircle, choose End Point Snap Mode and then select the ‘First Point’ at the end of the line and then choose End Point and select the ‘Second Point’ at the other end of the line segment. NOTE- if you were to choose the ‘First Point’ and ‘Second Point’ without selecting End Point you would have been able to accomplish the same thing- End Point is always activated unless another Snap Mode is in use. SHORTCUT KEY: E INTERSECTION- Use the intersection of two segments (arc or line) as the snap point. If an intersection does not exist then the intersection will be determined automatically after the two clicks have been made. HOW TO USE- Two clicks are required for this Snap Mode. Example- if two line segments, horizontal and vertical, intersect creating a cross and the intersection is needed as the starting or ending point, select Intersection and then choose the vertical segment and then the horizontal segment (or vice versa). The snap point will be set as this point where the segments intersect. SHORTCUT KEY: I CENTER- Ability to choose the center of a arc or circle. Can be useful with any function of the CAD to place geometry or select any type of starting or ending point. HOW TO USE- For example if a construction line is needed that will run through the middle of the a circle select the line function and then activate ‘Construct’, select Center Snap Mode and then choose Relative Snap Mode and then enter a value of 1 for DX and click OK. The line will start at the center of the circle allowing it to be drawn in the X axis directly in the middle of the circle. 19
