Hi everyone,

I am trying to create this curved surface wit multiple radii on autodesk inventor 2017, but I am unable to do so. I have attached the file with encircled areas aswell, kindly guide me on how to create a curved surface with multiple radii. Thanks

Welcome to the community..

First when posting you should always indicated what version of Inventor you are using so others can provide examples in the version of Inventor you're using.

Next post what you have so far and we can look at your sketches and the progress you have already done.

Hi! This should be doable in Inventor. If I were you, I would just do one half due to symmetry. Then focus on straight segments first. Make sure scale is correct. Then you will need to create a series of arcs. These arcs will need to be tangent to the neighbors. Let us know you run into any issue.

Many thanks!

I've started it ..but it's snowing in NC my son wants to play .. however here is a start, the R300 is fully done here

The 2 600 is to show you 1 full 600 diameter circle sketch I started with....

You have a C/L of 80mm for the R300, this is important ..

I'm working on the top part now ..

But you never mentioned what version you are on ...

I had to make an assumption about the location of the R35.

I would add the fillets at the base after Extruding.

Hi Mark,

The OP is using IV2017. He mentioned it in his post.

Cheers,

Igor.

Hi,

Thanks for the reply. I have done this so far (please see the attached file). I have calculated the dimensions from the given ratios (1 in 4 and 1 in 20). However, I am not certain that I am on the right path or not. Kindly, have a look on the progress I have made so far. Also, I am still confused on how to achieve the curve at the top of the rail. Please assist me on that as well in a bit more detail. I am also attaching a detailed drawing of the rail (file name Rail drawing) as well. please don't worry about the holes in the drawing they are not under consideration.

I'm looking forward your reply.

Cheers

Hi,

Thanks for trying that, I don't know how you did it, but it's really impressive. I have also tried doing it but i'm not sure if I on the right track or not. I am also attaching my .ipt and .stp drawing files and the original drawing of the rail, so you could have better understanding. Kindly, assist me with my drawing as it is part of my thesis and my entire project is based on how accurate the rail model is.

I am looking forward your reply.

Thanks

~~You should be posting your actual Inventor file and not always an image...~~

Nevermind, I just saw we posted at the same time.

First all your dimensions are not even matching the design. Look at the radius dimension.. You have a 600R mm radius and the design calls for 300R mm

Hi,

No the 600mm is the diameter.

Hi @Mark.Lancaster,

Please find attached the inventor files.

Sorry I thought that was a radial dimension in the image.. It was hard to tell with just a clipped image.. But then noticed after you provided the actual part.

Although there are other ways of doing this and @TheCADWhisperer showed you a way.. But look at my sketch 1 of Extrusion 1.. Look how I laid it out and I don't worry about the fillets. At first I was going to break it up in 3 sketches even to simplify it. Like one sketch for the base, one for the middle section and another sketch for the top portion. In the end keep it simple since this part has a lot of radius in the upper section.

Update: Sorry posted the wrong one.. Look at the updated Extrusion part.

Update #1: I guess I shouldn't be designing parts at midnight.. The 300 radius geometry was not constrained (tanget) and missing the dimension. So look at the new one I attached. Sorry.. Going to bed and closing my eyes and no more designing at this hour..

Ah, I see... I noticed the message was edited but I didn't know the inventor version was added to it. 🙂

Where in Australia are you?

Why did you not supply the detail view in the original post?

Your dimensions do not match the drawing dimensions - don't do calculations, use the geometry information.
