Hello JDMather

I have 'researched' your loft.ipt file and try to copy it step by step in my own CAD file from the cylinder.

But a few things I don't understand:

Where can I find the option 'Edges' in the menus?

What are the functions of those 3D lines you have drawn?:

When I thicken the wall-surface for instance with 10mm to the outside (to get a cylinder wall), how can I let these 'holes' filed up so that they are smooth rounded around the inlet ports?:

Thank you in advance!!

I did not know whether the information you provided before was to the inside bore of the cylinder or the the outside.

I was simply providing a quick example.  (For example, I didn't bother to get those sides between the ports created by parallel lines with parallel sides).

To model the actual geometry I would have to know more information and spend a day or two on experimentation.

Edges are edges of existing geometry by selecting a face or a surface.

Thank you for your answer.

But I don't understand it quit well. For question 2 and 3 I'm still looking for an answer because I don't know yet how I could fill those 'holes' up arround the inletports.

And I have searched again for more then an hour but I can't find the option 'edges'. Could you please let me know where to find it?

Thank you.

I am sorry that I reply another time, but after days of searching on the internet, help topics... I still can't find that option 'edges'

And also the other problems, I can not solve.

I hope that someone could help me find that option, and could help me solve those other problems.

Thanks in advance! I really appreciate it, because it get's me a bit frustrated this problem after 2 months

When you select a face or a surface Inventor selects the Edges.  Edge selection gives more functionality than sketch selection.

You should put your part aside for a bit and go through the tutorials in my signature.

Thank you, now I finally found the 'edge function' and therefore I was able to draw the inlet ports.

For now, the cylinder is finished exept for one last anoying thing...

For some reason I can't 'Thicken' the cylinder wall, or 'extrude' it between the two sketches...

Could you please help me with this last step?

Then this model is finished, and I will start with some Inventor courses to learn more of it (basics for instance).

Here is the file:

Hope you really could help me with this last step.

Thanks in advance!
