Dabbling in Fusion 360

A question of the experts

I have been trying to create a .stl file of this simple body:



What is generated is this:



The part I am interested is the small rectangular structure bottom left. What's happening, this same thing has happened with another project?
To answer the obvious questions, I have tried to create the .stl multiple time each produces the same result and there are definitely no other bodies visible during the process, I have even closed Fusion 360 completely and reopened it before generating one of the test.

Hi Rob,

Certainly worth a try but ..... Moved it 50mm left, deleted existing stl and recreated it.

I was about to say exactly the same thing Rob. Although it's very hard to see Andy's drawing to make an exact diagnosis.

You don't need 2 sketches to make the lamp pole. Use a single one and draw a half section of the pole through the centre line.
Then use the revolve function specifying the centre line as the axis.

If you send me the sketch I will draw you an example and send it back to you.

Andy I manged to screen grab your sketch so here we go.

New design
Create Sketch on front side
Insert canvas select front side
Edit sketch and draw half profile of lower part of pole



Closing the sketch gives me this. I have selected both parts of sketch.



I will explain random internal vertical in a minute.
Then create revolve and selecting righthand vertical as axis gives me this



Alternative. If I only select part of drawing but still select righthand vertical I get this





Obviously all very simplistic but it gives you the idea how to do it. Let me know if you need owt else

Andy,

It's just a case of getting in and playing, yes some things will go wrong but that's just part of the learning curve. The first 2 or 3 wagons I designed probably went through 10 versions before I got them to a point where I was happy. I'm lucky having commercially designed software for 30+ years, I look at things slightly differently. I can see 3-4 different designers in the functions I use, the differences are minimal but they are there. Once I have a handle on which variation is being used I can quickly grasp the various options available for a function. Some things stump me, like the flutings on your lamp post - I haven't a clue how to tackle them, equally 3d sketching just leaves my brain fried, it's something I really need to get a handle on.

Rob,
I'll be fascinated to see what you come up with but what do you think to those "rectangular but curved slots in the lower portion of the lamppost. They look like a real problem as well.

Andy,
Do you have a phot of the lamppost so we can get a clear view of the shapes?
