The sketch is now finished and includes the final dimension values. Also, set the angle between lines 2 and 3 to 135 degrees using the same approach (double-click the angle and change the value). To do this, simply double-click the dimension value and enter a new value. To finish the sketch, set the length of line 2 to 20mm. Note that now the dimension on line 3 is gone. To get the dimension back on line 1, add an inferred dimension to line 1 like you did for line 4. An over-constrained sketch has more dimensions and/or constraints than the number necessary to completely define the sketch.

If this dimension had not been removed, the sketch would have become over-constrained. Note that adding the dimension to line 4 removed the dimension on line 1. Enter 20mm, the result should be the sketch shown in Figure 6. Left-click to set the value of the dimension. Drag the dimension to the location shown in Figure 5. Click on line 4, a dimension will appear that moves with your cursor. NX will then let you select a drawing feature to dimension. To do this, click the Inferred Dimension button in the Sketching Toolbar (Figure 4). To change this, we need to add an Inferred Dimension to line 4. As constrained by NX, the length of line 4 is based on the other dimensions and not explicitly set. For this sketch, it is desired to constrain the length of line 4. Sometimes it is necessary to add dimensions manually to replace ones added automatically.

These dimensions work with the constraints to define the sketch. Use Show All Constraints to make sure these constraints are added.ДЄs you draw, note the dimensions added by NX. The important aspects are getting the general shape correct and to make sure that vertical lines are vertical and horizontal lines are horizontal (it you get close NX will constrain them). When drawing the lines, dont worry about getting the dimensions exactly right, just get them close. Start a new line at the origin of the sketch (XC 0, YC 0) and draw the lines shown in Figure 3 using the sequence indicated with the red numbers. Select the X-Y plane and click OK in the Sketch dialog. To start, click the Sketch button in the Sketching Toolbar. This sketch will be revolved to form the base. Initial SketchThe first step in creating the part is to draw an initial sketch for the base of the piston. These features include: An initial sketch A revolution A sketch on a surface An extrusion Placement of holes An edge blend Addition of grooves A shell operation It consists of several features that must be created in sequence. The part to be drawn is a piston for a small airpowered device. Make sure you save the part in a location that will be accessible later (S: drive, etc.). To get started, open NX 7.5 and start a new part file. This tutorial will cover the creation of a fully constrained part from scratch. In this tutorial, sketch constraints and dimensions will be covered in more detail. Basic sketching was covered in Tutorial 1.

The IDE20 tutorials for NX will focus on basic 3D drafting and component modeling.Дrawing a PartThe starting point for most parts is a constrained sketch.
