 Before performing the every script, create a new drawing from a template acad.dwt. Download s_init_acad.lsp. Run the script. Перед выполнением каждого скрипта, создайте новый чертеж с шаблоном acad.dwt. Загрузите приложение s_init_acad.lsp. Запустите скрипт. 1.1. Crt_UV_Loft_Part_Tor_i (ver 2012-2014).scr Script demonstrates the creation on 3D Mesh of net of curves of high quality and creation on net of curves the standard Lofted Surface. AutoCAD method of modeling the Lofted Surface not creates the surface of high quality. 1.1.

Crt_UV_Nurbzs_Part_Tor_i (ver 2012-2014).scr Script demonstrates the creation on 3D Mesh of net of curves of high quality and creation on net of curves the NURBzS surface of high quality. Method of modeling the NURBzS surface creates the surface of high quality. In this example the surface geometrically exactly approximates the part of torus. 2.1. Сценарий Crt_UV_Nurbzs_Part_Tor_i демонстрирует пример построения бикубичесой NURBZS поверхности на сети точек, снятых неравномерно с торовой поверхности. . 2.2. Crt_Nurbzs_Arch Izo 0 (ver 2012-2014).scr Script shows an example of modeling of a bicubic NURBzS surface without the control of geometrical similarity over a network of points 3 * 3, modelling complex surface of type of the architectural form. Boundary polylines of lines and columns have various forms on a horizontal projection. Average polylines of lines and columns rectilinear. The program under script Crt_Nurbzs_Arch Izo 0.scr creates a cubic surface with an option of isogeometrical definiteness = 0. Forms a network of points on the constructed surface. Shows occurrence of oscillating parametrical lines on a horizontal projection. 2.2. Скрипт Crt_Nurbzs_Arch Izo 0 демонстрирует пример построения бикубической NURBzS поверхности без контроля изогеометричности на сети точек 3 х 3, моделирующую сложную поверхность типа архитектурной формы. 2.3. Crt_Nurbzs_ArchIzo2 (ver 2012-2014).scr Script creates a surface on the same network of points that was used in the previous script Crt_Nurbzs_Arch Izo 0. Creates bicubic NURBzS a surface with an option of isogeometrical definiteness, equal 2. Forms a interpolated network of points on the constructed surface. The form of a interpolated network shows geometrical definiteness NURBzS of a surface on a horizontal projection. The option of geometrical definiteness equal 2 is recommended to be used for strict geometrical definiteness of surfaces of 1-st order of smoothness on networks of points with rectilinear forming networks, flat sites of a network. Provides strict geometrical definiteness, exact approximation through points and 1-st order of smoothness. Generally the network of v-curves created on a network of points, is not kept in a surface. 2.3. Сценарий Crt_Nurbzs_Arch Izo 2 показывает пример построения бикубической NURBZS поверхности с использованием опции строгой изогеометричности, равной 2. 3.1. Crt_Bsp_Klein55 (ver 2012-2014).scr Script demonstrates the method for constructing the integrated surfaces of complex topology. In this example script constructs the one sided surface as bottle of Klein. The NURBS surface is constructed on s-frame of float format. Shows a network of lines of a surface. Subdivides a s-mesh. Shows a network of curves on a surface. Interpolates a surface. Forms object 3d Mesh. Renders the object. The surface is everywhere of order G44 of smoothness. 3.1. Crt_Bsp_Klein55 (ver 2015).scr Script demonstrates the method for constructing the integrated surfaces of complex topology. In this example script constructs the one-sided surface as bottle of Klein. Script draws a s-mesh. The bidimentional file of points of a s-mesh is formed definitely for maintenance of closing of a surface and the identical order of smoothness G44 in any point of a surface, including points on lines of closing of a surface.

Script Crt_Bsp_Screw_i.scr draws the closed line on a circle with non-uniform distribution of points. Forms a network of points by copying an initial polyline. Copies rise on axis Z, rotate around of axis Z and are scaled. Forms a set v-curves on a network of points. V-curves geometrically precisely model circles. Creates on a set of v-curves a set of forming curves. Forming b-spline curves keep high quality of v-curves (see script Crt_BSp_Vcrv.scr). Creates directing v-curves on a set of s- polygons of forming b-curves. Creates directing b-spline curves on a set of directing v-curves. Directing b-spline curves keep smoothness of curvature of v-curves and improve smoothness of torsion of spatial curves (see script Crt_Spt_Bsp.scr, Crt_Spiral_Bsp).
