How to model attached files in Inventor?
I see a few ways of doing this.
The first way I see is to create the bodies of the main cylinders first.
Make sure these are created as individual solids when making the ipt file.
Then make the profile that connects between the two cylinders from a side view. Make sure that is also made as another individual solid as well.
After you have the 3 solids, use the combine command to make them all as one solid.
Next I'd make the small cylinder extrusions off the sides of the larger cylinders.
Finally, add the necessary holes.
This is would be my initial approach to this model. But of course, there are always others.
I agree with Jonathan.
The way I solve problems like this are:
A - evaluate the model. Visualize what sketches and features make it up.
B - based on the drawing views, determine the best plane to start sketching on so your model is made in the correct orientation.
1 - create one or more layout sketches with the critical dimensions
2 - Add material (i.e. the two cylinders)
3 - Add more material (i.e. the "T" span)
4 - Remove material (i.e. various holes)
5 - Fillets & chamfers
There are a dozen ways to create models like this. None of them are better than another unless there is additional criteria to consider.
I like putting each feature as a separate feature. Some people like to put several features into a single sketch. Neither is wrong, but more features allows individual elements to be easily suppressed if the model later changes.
Three odd things with the drawing:
1 - It is "backwards", but I suppose to the rest of the world outside of the US, it is normal. First angle vs. third angle drawings always look confusing to me
2 - Both section views are labeled AA. This does not seem normal.
3 - It is unclear what size the two smaller holes are. It looks like they are labeled M16, but the leader lines seem to go to the outside of the 2mmx45° chamfer. Does anyone know how to interpret those hole diameters?
