Practise exercise 2

The exercise below can be made using part design workbench as well as surface design workbench. Modeling the part is quite straightforward. After making the centre hub, you can proceed with modeling blades, which would require you to model it with the use of curves whose details are provided.

Exercise

Making seventh part

This is perhaps the easiest exercise that requires just two steps. You need to model the section and a centre curve about which the section will be swept to create the 3D model. 

Exercise

Making sixth part

The exercise below is quite easy. You may be tempted to model this using solid combine feature. However, there's a rather easier way to make it. You can go about modeling a tear-drop shape first by using shell command and then successively making holes and pockets as desired and this will give you the desired part.

Exercise

Making fifth part

In comparison to the last part you modeled, this should be relatively easy. Due to the reason that there are similar features and sketches for these can be easily copied and utilized multiple times.

Exercise

Making fourth part

The part appears to be a casting. To make the part below, I would suggest you to download the image first using right click. Modeling the part is very straightforward and easy. We need to first make the complete sketch using the dimensions as shown below. The section view provides information about the depth of pockets and extrusion of profile.  

Exercise

Making third part

The drawing on your right can be used to make a 3D part. The top view and the front view sufficiently describe the part.

Exercise

We may first proceed to make the base of the part, followed by the top section containing two holes of diameter 8mm. Subsequently, we may create the two sections with hol of dia 25mm. In this exercise, we will demonstrate, how to use selective parts of a sketch, copy and pasting the sketch, changing sketch support and using a positioned sketch to orient sketch as per our needs.

Making second part

The exercise is quite simple and can be completed in a couple of steps. Perhaps, we can first start with solid combine feature and combine two sketches, that should give us a majority of the part that we wish to create. Secondary features like through holes, pad, pocket etc. can be made next.

Exercise

An alternative way might be that we create a solid with 60mm width and 46mm depth and 48mm height and then carve out material step by step that's not supposed to be there.

Making first part

The exercise is relatively easy, the beginners however may have trouble figuring out how to approach and where to begin. This has a lot to do with lack of practise with options that can be used for creating reference planes and other reference elements. If you have not practised reference elements and are not familiar with the various options that exist, it's better to practise that first.

Exercise

The part can be made with the use of pad, hole and stiffener commands. We may need to make a couple of sketches for this on different planes. Once you see someone make it, it becomes relatively easy since it give a perspective as to how such a problem can be approached. Going further, you would be able to come up with more unique ways to make such parts.
