Chapter 4: Creating Simple Parts, Assemblies, and Drawings
- Select the top angled face of the angled frame member and the corresponding flat
face of the machined part. Figure 4.19 shows which faces to select. Make these faces
coincident. In this case, the parts are already in the correct orientation, and so there is no
need to pre-position them. Click the green check mark icon to accept the mate.
FIGURE 4.19
Selecting mating faces
- One more mate is required to fully define the position of the machined part. Drag
the part and verify that it slides up and down the angled weldment member. Find the
two tapped holes in the weldment and slide the machined part so that the holes appear in
the counterbored slot. Ideally, the holes should be symmetrical with the part, but the slot
was created to allow room for adjustment.
- Expand the machined part in the FeatureManager and select its Front plane. From
the View menu, turn on the display of temporary axes and Ctrl+select the temporary axes
in the centers of the threaded holes in the frame, as shown in Figure 4.20. Select the
Symmetric mate on the Advanced Mates panel. Turn off the display of temporary axes
when the mate is complete.
- Through the menus or Assembly toolbar, click Insert Component and use the
Browse button to find the existing Chapter4Screw.sldprt part on the CD-ROM,
or on your hard drive if you have copied it there.
- Notice that this part behaves differently in certain situations. For example, when the
cursor is over empty space, it is attached to the centroid of the part, but when the cursor
is over a flat or cylindrical face, the part snaps to that face. This is because the part uses a
Mate Reference, enabling planar and cylindrical faces to get Coincident and/or Concentric
mates automatically when the part is dropped on them.
