Fillets and Projections

[gunnykiln]

Fillets:

I am having some difficulty making large fillets on several parts. Does anyone know of a good faq, tutorial, or examples of fillets on along complex curve intersections and edges? I have a small part I can email as an example.


Projections onto non parallel planes with convert entities:

This might be hard to explain without images, but I am modeling something based on Top, Front, and right sketches. I have to do an extrusion from a plane that is at roughly 30 deg on the YZ plane. For the shape of my extrusion I need to project lines from the top view sketch (XZ Plane) onto my angled sketch. But when I do a convert entities from the top view sketch onto my 30 deg YZ sketch the lines are in the wrong locations from what I need. In other words when I look at the 30 deg sketch from the top view looking at the top plane sketch I want the lines as coincident.

This should be simple, so I am probably missing something obvious, so how can I get a true projection from the top view onto the 30 deg sketch?

For the projection, make sure you're viewing things Normal to your sketch plane (View toolbar, pick plane, hit the Normal To button)--that will put things in the exact location you convert entities from (no surprises).

What's failing about your fillets? If you're using surfaces, keep in mind that if you go from an internal fillet to an external fillet (can happen where two free-formed surfaces join), you're asking SolidWorks to do something non-rational (hold the same radius while inverting its direction). That may be a bit tricky to envision, and I'm not even sure if that's your problem. I'd recommend posting an image (or the error message) to take a look at.

Here is a pic of a sample part I am trying to fillet (hopefully the link works). I have several different parts but with many of the same problems filleting.

For the sample part,

I am trying to fillet the intersection of the lofts "Fillet 1" and "Fillet 2" so that there isnt a flat vertical edge left. (Fillet 1 meets Fillet 2 all along the edge)

I also am trying to make a large fillet at the "Fillet Loop" location. The face fillet doesnt work on this.

Try the internal fillets first--maybe use a Variable or Face Blend--the externals next ought to be simpler.

OK, after screwing around with it for several hours I was able to get some large fillets going. Originally my loft profiles were one segment splines. I found that if I broke the spline in a few places I could use variable fillets.

 

[Theophilus]

You can add segments of variation to variable fillets. Also, another aspect of variable fillets that's nice is bringing the fillet down to a value of zero.

I had to do that at the end segments in order for it to work.
