How to model attached files in Inventor?
1 Answer
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?
