Please Help - New to Fusion

[matthewcampbell96]

Looking for some help in modelling this drawing. I am new to Fusion and I am still figuring out its quirks. I can easily model the top and bottom plates but I am struggling to model the support legs (I was attempting to make these rectangular with chamfered edges to pick up the bottom plate) due to the 45 degree incline of the bottom plate. Any help would be greatly appreciated! Also, please note that the 500mm dimension to the top of the bottom plate is incorrect and should be 625-173.24 due to 245 sin (45).

p.s. I appreciate that the powerpoint is a poor drawing - this is what I received.

Can you File>Export your *.f3d file to your local drive and then Attach it here to a Reply?

Also, do you have a picture of something similar that already exists in the real world?

[Warmingup1953]

Is the "245" a circular disc inclined 45 degrees? is there a Plane view or any other references?

[Warmingup1953]

Maybe like this?

[matthewcampbell96]

That's correct - 245 diameter inclined at 45 degrees.

[matthewcampbell96]

Yeah, like that. To connect the top and bottom plates, the legs will need to be at angle as well as they will not pick up the geometry if extended straight down from the top mounting flange.

[matthewcampbell96]

Here's the very poor attempt - I have changed the bottom plate to an ellipse to try and pick up the support legs but would prefer for this to be circular. Hopefully you can get a better idea of the general design, however poor it may be at present. Essentially I want to make a deflector plate in which the top mounting plate will be sandwiched between flanges at the entry to a fluid bed dryer. This is to divert flow and prevent clumping. You will also notice that I have the long leg at the front in this but this is also a poor design as it is in the way of the flow path. I have assumed 5mm stainless steel plate for the entire design.

Supports will be fillet welded so need enough clearance for at least a 3mm throat.

[Warmingup1953]

My basic interpretation. I have suppressed some Timeline features.... a fresh start will help. Will you 2D Plasma cut?

[laughingcreek]

chamfer (and fillet) are edge finishing tools.  I would avoid using them as modeling tools. (either for setting a construction plane or for setting the angle of a bearing surface.

put your trig book away and let fusion figure out what angles to cut things. attached is a possible workflow-

[matthewcampbell96]

Thanks for the feedback! This is a very clear workflow, however, I have one more question. The 330mm diameter plate is to have a 245mm bore, so the supports will need to run at an angle in order to mate with the inclined plate. What is the best way to model this? This makes an extrusion complex as the sketch planes are not aligned so I am not sure how best to do this in Fusion.

Sweep - profile up the centre line as a Path.

Do one, pattern for 3.

cut the legs with Split body.

Might help….

[matthewcampbell96]

Thanks Dave, are you able to provide an example?

[matthewcampbell96]

This is what I have managed so far - certainly making improvements. Open to some suggestions on improving the sweep path of the two front supports. I was struggling to pick up the equally spaced sketch profiles so these are not perfect. Really appreciate all of the great advice/feedback thus far!

[laughingcreek]

using sweep with a profile that isn't perpendicular to the path will result in a thinner profile than intended.  You'll need to use a construction plane "along a path" for the profile.  if your going to do that anyway yo might as well use extrude with the extrude distances se to "extrude to" to save the extra step of splitting bodies and removing extra bits.

see attached.

Apologies, laughingcreek - been away for a couple of days so only just caught up with your response. It appears that you forgot to attach your file?

so it would seem.  here you go.
