Performing scaling |
Scroll |
Scaling is executed by the Scale 
command.
Step-by-step instructions
1.Select the scaling objects in the Design Tree or in the graphic area.
The selected objects are highlighted in the graphic area, their names appear in the Objects field on the Parameter Panel.
The graphic area displays the phantoms of the scaled objects and their bounding box whose subsequent changes allow to evaluate scaling visually.
2.Scaling spatial curves and points in a model results in the creation of new curves and points, which are part of the operation Scaling. Source objects do not change. You can hide them or keep them visible using the Hide original curves option.
•Enabling this option means that the source curves and points will be hidden in the graphic area after the scaling is complete.
Note that in the case of deleting the Scaling operation, the visibility of curves and points is not automatically restored.
•Disabling the option means that the source curves and points remain visible in the graphic area.
You can also manually disable the visibility of source curves and points after the operation is complete (see section Managing visibility of objects).
3.As a result of scaling solids and surfaces, their proportions and/or dimensions change. If necessary, copies of the original solids and surfaces can be saved in the model using the option Save copies of solids and surfaces.
•Enabling the option means that as a result of the operation the number of solids/surfaces in the model will increase. The copies of source solids/surfaces will be created. They will be included in the operation of Scaling. If in a subsequent operation Scaling is deleted, the created copies will also be deleted. The number of solids will become the same as before.
•Disabling the option means that the number of solids and surfaces in the model does not change.
4.You can select the coordinate system in which the scaling of objects will be performed. To do this, use controls of the Coordinate System section. Details...
5.Using the group of elements Scaling Center specify the scaling center — the point that will remain stationary during scaling. By default, the center is the starting point of the current model's coordinate system. How to set the center:
•Enter the point coordinate values in the Coordinates field (coordinates are specified relative to the coordinate system selected in the scaling operation). The field has three boxes to enter the X, Y, and Z coordinates.
•Selecting a point object. To do this, click in the Snap point field, then specify a point object in the graphic region. The name of the selected object is displayed in the field.
•Plotting a point. To do this, click Build Point 
button located to the right of the Snap Point field. Will start Subprocess of plotting a point.
6.In the Scaling Method element group, select a scaling option and specify the coefficient value. To do this, set the toggle switch Evenly/Per CS Axes to the desired position:
•Evenly — scaling is performed with the same coefficient for all coordinate axes. Specify the coefficient value in the Coefficient.
•Along the CS axes, scaling is performed with different factors for each axis. Values of the coefficients are specified in the fields Factor by X, Factor by Y, Factor by Z.
7.If necessary, specify the operation name in the Properties section.
8.To complete the operation, click Create Object 
.
The scaled objects appear in the graphic area, and the corresponding operation icon — in the Construction Tree.
9.To complete the command's work, press the Finish 
button.

You can set the scale center and coefficient value(s) in the graphic area using defining points (for information on defining points, see section Defining Points of Objects). |

When further editing of the model whose construction involved the Scaling command, you should consider the following. •A scaled sheet solid loses properties that are characteristic for this type of solids. •When constructing arrays of objects the scaling operation performed on the object earlier is ignored. Instances of arrays have such dimensions and position in the model as if the arrays were constructed before performing the scaling. •Matings overlayed on components (or solids) ignore subsequent changes of dimensions and positions of objects caused by scaling. To fix the matings, edit them, re–specifying the mated elements or objects. •Only solids, surfaces, and curves themselves are scaled, while their source objects — sketches, etc. — are not changed. The dimensions and designations created for the objects being scaled, change in the following way: •Designations and manually set dimensions are redrawn according to the new position of their base objects, and dimension values are recalculated, •The cosmetic thread is restructured in accordance with the position of base objects, but the threading parameters (diameter, pitch, length, etc.) remain unchanged. •The derived dimensions do not change. |
