Editing a particular segment in contour Hatches and Fills To edit a contour segment, do the following steps: - while in contour editing mode, select the desired contour segment; - select the construction element defining the new contour segment: line, circle, ellipse or spline (use the appropriate option for element selection). The end nodes of the contour segment must be snapped to the selected construction element; - confirm changes by the or key. Let’s review an example illustrating a particular contour segment editing. The diagram shows the original hatch constructed along construction lines using the “Outline” option. Here, a straight-line segment is to be replaced by a spline. To do so, call the command “EH: Edit Hatch” and select the hatch. Then, turn on the contour editing mode using the option: Contour edit mode Select the hatch contour. The following diagram shows the situation after the hatch selection. The contour is highlighted, and the nodes are marked by little boxes. Move the cursor over the desired segment of the contour and click the left mouse button. The selected contour segment also gets highlighted, and the nodes marked by larger boxes. This state is shown on the center diagram. Move the cursor over the spline constructed through the nodes of the contour being edited, and select it as a contour segment by typing . Similarly, one can replace a contour segment by an arc or ellipse, if the respective circle or ellipse is constructed based on the marked nodes. Simply use the appropriate option: or . If the new contour segment was not constructed based on the marked nodes yet passes through them then the contour segment editing should be done via the option “Switch to ‘Insert Point’ mode” (the icon or key). This option functionality is described below. The edited segment will then assume the desired shape. The system is still in the mode of modifying the selected contour segment. If the manipulations with this segment are over, complete the contour segment modification mode. To do so, press the icon in the automenu. The option is not available for editing the contour. Therefore, it is impossible to snap a contour line to a graphic line. If a contour segment is to be replaced by a graphic line while editing, as, for instance, a wave line, then you need to construct a spline based on the wave line. The intended hatch contour segment can then straightforwardly be replaced by the spline. S 307
<strong>Fundamentals</strong>. Two-Dimensional <strong>Design</strong> Linking arc contour segment to helper node 308 If the edited contour segment is an arc then the option for linking to a helper node becomes available in the automenu. This node will be defining the choice of an arc constructed on top of the circle to be used for the hatch contour. As the drawing gets modified, the hatch contour will pass by the arc nearest to the linking node. Let’s review an example where a construction line position is modified with respect to a reference line driven by a variable “K”. Both circles here are linked to a node on the drawing in order to ensure correct position. The left diagram shows the hatch contour in the original configuration (K=1). Let’s link the arc segment of the hatch contour on top of the outer circle to the marked node. To do this, do the following steps once in “EH: Edit Hatch” command: - Call the hatch contour editing option ; - Select the arc; - Call the option ; - Select the linking node. The right diagram shows the modified drawing with the “К” key equal to (-1). The contour segment on top of the upper circle was linked to the marked node and adjusted correctly. The contour segment on top of the second circle was not linked to the node, which resulted in an incorrect configuration. To clear or redefine the linking node, use the option . Deleting a node on a contour To delete a node on a contour, do the following steps: - Call the command “EH: Edit Hatch”; - Select a hatch for editing; - Turn on the contour editing mode (the icon or key); - Select the contour segment the node is snapped to (point at with the graphic cursor and click ); - Select the node (point at with the graphic cursor and click );
