Hi all,

I am developing a range of replacement scissor handles for a company manufacturing disability living aids and have now come to creating 3D ready for a few SLA prototypes.

I am a little rusty in 3D as I've been working for bank for the last two years so am looking for some really great tips for modeling something of the like with very little uniform curvature throughout.

Just as an idea:

I use both Solidworks and Rhino and know the two would require very different approaches. I would rather complete the model in SW as manufacturers have asked for parametric data, and also I've had many problems in the past with sending Rhino models to rapid prototyping machines.

Thanks in advance!

PS Good to back on the forum after all these years!

From what you have there it looks pretty straight forward to do in solidworks.

Its alsmost easy enough that you could to do it as a simple extrude and add fillets afterwards, but I do see some curvature there that would probably better suited doing a simple loft and cut loft. Just make one side profile, then copy that sketch on to an offset plane, and then connect with guide curves to define the in between curvature. Create loft, then repeat the same steps for creating the inner cut loft.

If you have a bunch of these that you need to model and are looking for some assistance with 3D SolidWorks modeling feel free to shoot me a PM.

Best of luck

Thanks pal that was very helpful. I did have a go with profiles and guide curves but lost patience. I've obviously also forgotten that good models need time (and coffee).

I also completely forgot I had T-Splines installed in Rhino so have been able to mock up a near perfect in a matter of minutes thanks to a helpful Novedge vid on the tube. I'll definitely consult if I need any SW help later on.



Thanks again
