Sketch plane

For this example, we will place a hole in the object. Return to the 2-D sketch toolbar. We must select a sketch plane in order to draw on the surface of the object. In parametric modeling software, a sketch plane... 

In parametric modeling software, a sketch plane is the surface on which a geometric feature is drawn.

For the block example, a plane that is parallel to the top (or bottom) face of the base block was created first (by simply clicking more than three points on the surface). The plane is offset vertically to ensure a proper intersection between the sketch plane and the polygon mesh. The geometric entities obtained from the intersection are planar spline curves. The Auto Sketch capability of Rapidform can be used to extract a set of regular CAD-like line entities that best fit the spline curves. These standard line entities can be joined and parameterized by manually adding dimensions and constraints for a fully parameterized section profile, as shown in Fig. 18a. 

Figure B3.2.4. A schematic illustration of an energy-independent augmented plane wave basis fimction used in the LAPW method. The black sine fimction represents the plane wave, the localized oscillations represent the augmentation of the fimction inside the atomic spheres used for the solution of the Sclirodinger equation. The nuclei are represented by filled black circles. In the lower part of the picture, the crystal potential is sketched.

Figure 5, Sketch of a conical intersection. The vectors x and X2 are the GD and DC respectively, that lift the degeneracy of the two adiabatic surfaces, The plane containing these vectors is known as the branching space.

The flexibility factor k applies to bending in any plane. The flexibility factors k and stress intensification factors shall not be less than unity factors for torsion equal unity. Both factors apply over the effective arc length (shown by heavy centerlines in the sketches) for curved and miter bends and to the intersection point for tees. 

The papers which introduced the concept of a dislocation all appeared in 1934 (Polanyi 1934, Taylor 1934, Orowan 1934). Figure 3.20 shows Orowan s original sketch of an edge dislocation and Taylor s schematic picture of a dislocation moving. It was known to all three of the co-inventors that plastic deformation took place by slip on lattice planes subjected to a higher shear stress than any of the other symmetrically equivalent planes (see Chapter 4, Section 4.2.1). Taylor and his collaborator Quinney had also undertaken some quite remarkably precise calorimetric research to determine how much of the work done to deform a piece of metal...

Figure 4-10. Sketch of Hie operations applied ui a colacial dimer formed by two slilbene molecules separated by 4 A when investigating the role of positional disorder. The modilicalions are induced by (I) the translation of one molecule along the chain-axis direction (II) the translation of one molecule along the in-planc transverse axis (III) the rotation of one slilbene unit around its long axis and (IV) the rotation of one slilbene molecule around the slacking axis while keeping the parallelism between the molecular planes.

In Fig. 4.4, the starting points (initial estimates) are denoted by circles in the A, B plane the evolution of the successive approximations is sketched by arrows that converge on the optimum, albeit in a roundabout way. The procedure is robust no local minima are apparent the minimum, marked by the square, is rapidly approached from many different starting points within the given A, B plane (black symbols) note that a B-value > 0, an A-value < 0, and combinations in the lower left comer (gray symbols) pose problems... 

In order to demonstrate completeness of a SAXS fiber pattern in the 3D reciprocal space, it is visualized in Fig. 8.16. The sketch shows a recorded 2D SAXS fiber pattern and how it, in fact, fills the reciprocal space by rotation about the fiber axis. V3. Let us demonstrate the projection of Eq. (8.56) in the sketch. It is equivalent to, first, integrating horizontal planes in Fig. 8.16 and, second, plotting the computed number at the point where each plane intersects the S3-axis. 

Figure 1,2 Atomic arrangement on various clean metal surfaces. In each of the sketches (a) to (h) the upper and lower diagrams represent top and side views, respectively. Atoms drawn with dashed lines lie behind the plane of those drawn with thick lines, Atoms in unrelaxed positions (i.e. in the positions they occupy in the bulk) are shown as dotted lines. From G.A.

Past the transition state of the photoinduced reaction, J, the system goes down the repulsive product surface, P, until P crosses the intersection with the reactant surface R. These two surfaces are sketched in Fig. 16a. Their intersection is a parabola (the central line in Fig. 16c) whose projection in the X -Yi plane (straight line in Fig. 16b) is defined by equation (67). 

Fig. 10 Estimation of the tilt angle for an alkane between gold electrodes, determined by fitting the computed IETS spectrum with the experiment (panel b below). Result is a 40 degree tilt angle perpendicular to the plane of the carbon chain, as illustrated in the lighter shade structure in the sketch (b) above. Sketch (a) above and panel (a) below refer to the alkane tilted in the plane of the carbon chain. The structures in sketch (a) do not fit so well an those in (b), suggesting the methyl group position shown in (b) above. From [107], Reproduced by permission of the PCCP Owner Societies...
