Element Modification

Setting	Description
Extend/Trim	Used to extend or trim shapes with intersecting shapes or lines. ? Allows complete shapes to be cut or extended at boundaries, similar to the Stretch command for the stretching and cutting lines. You must select the shape at the end to be cut and then select the cutting line. The boundary is completely formed by a construction line. An imaginary plane passing through the construction line, normal to the active coordinate system is the cutting plane used. If the plane is slanted, the modified shape has a slanted plane as well. By using this function, shapes that are too long or too short can be adapted to fit after their insertion.? When you enter a value in the Distance field of the main dialog, the shape is trimmed (shortened) by this value after it is cut. The distance refers to a vertical distance between shape and cut plane. The shape is cut at an imaginary plane, the line being oriented vertically to the active coordinate system plane. Working in a “top” oriented view simplifies your work, since the shape is cut at the line. If the shape can intersect with the line (consider the line to have infinite length), the shape is cut. To extend the shape, hold down the `Alt` key while clicking the end to be extended. Figure 1. 1) UCS plane, 2) Cut line, 3) Imaginary cut plane Figure 2. 1) Cut line, 2) Cut plane, 3) Removed where selected ? Allows the shape to be cut or extended at another shape. When the shape is cut, the shorter section is always cut off. Click the shape to be cut and then the shape along which this shape is to be cut. Figure 3. The plane intersected by the centerline (or the extended centerline) of the shape to be cut is the cut plane (top, middle). If the centerline does not meet any surface, no cut can be made (bottom). Note: A logical link is created between the parts if this option is applied. If one part is modified, the cut is automatically updated. Distance ? Trims the cut shape back by the entered value from the cut plane. Straight cut ? Trims the cut shape perpendicular to its centerline. Extend to line ? Trims the cut shape exactly along the the cut plane created by another shape's intersecting plane or by a line.
Divide	Used to divide a shape at a cutting line into two shapes. A single shape, a plate or several elements can be divided into two independent elements. ? When using this function, start by selecting the shape to be divided. Then the cutting line. When you enter a value for Distance, both new ends are shortened by this value. Note: Depending on the setting, you can divide several elements at the same time. However, the distance refers to a vertical distance between shape and cutting line. Distance ? The two new shapes are shortened by this value at the cutting line. The overall gap is double the entered value. Divide at ? Used to select how the cutting plane is generated. Point ? The cutting line is created with a single point, which is perpendicular to the centerlines. Line ? The cutting line is created with a line. If the line is slanted, the shapes are divided accordingly. Plane ? The cutting plane is created by entering three points. The shape is divided along this plane. Note: The information for the parts lists is identical for both parts with that of the initial shape, except for the length.
Connect	Used to join two shapes into one shape. The shapes must exactly aligned (coplanar and have a coincident point) to use this option. - When using this function, select the two shapes to be combined. If they are not in alignment, the function is aborted. If they are aligned correctly the two shapes become one shape. Note: The information for the parts lists of the new shape is identical with that of the first selected shape, except for the length. Type check - When on, the two shapes must be of the same type to be joined. Tip: Press and hold the `ALT` key to prevent the shape and position from being checked. Then, you can combine any shape with any shape.
Other	Opens the Notch dialog which is used to insert simple geometrical shapes of outlets and countersunk parts into shapes.
Polycuts	Used to cut out shapes along any freely drawn contour (poly-line). You can create notches that can not be made with Notch functionality. You can also subtract one shape from another to create penetrations, to create slotted tubes, penetrated handrail posts or other combinations. Note: If you enter a value in the Gap input field of the main dialog, the cut-out is regularly extended to all directions by the indicated value to gain some ?space? for inaccuracies of production. Note: In any case, the cutting polygon is extended to the top and to the bottom in the coordinate system's Z-plane. Therefore, ensure your UCS has been selected accordingly. In case of a direct use of this function via key-in, the current settings of the main dialog apply. ? Use this option if you do not have a contour element to select. Rather, enter the data points to create the contour. Make sure the contour is a closed polygon. ? Use this option if you have a contour element to select. ? Use this option if you want to subtract the contour of another solid from the selected object (penetration or solid to be subtracted). ? Use this option for straight, hollow shapes only. The internal portion of the subtraction between the hollow shapes and other straight shapes or plates is retained. Figure 4. Before (left) and after (right) using an inverse boolean subtraction on a hollow shape Update reinforcement ? When on, reinforcements are updated accordingly. Position ? Sets the option on what height the cut be performed: Complete ? When selected, the cut travels through the entire cut shape. Upper half ? When selected, the cut travels through only the upper portion of the cut shape. Lower half ? When selected, the cut travels through only the lower portion of the cut shape. Gap ? Used to specify a gap by which the cut contour is increased before the subtraction.
