i need to know how to model the attached part and keep the circularity of the bottle
this is my attempt but I faced a problem in circularity of the bottle and connections with upper and lower parts, it is not smooth connection
Here's my attempt (SW 2014 SP5.0)...
Chris, Would you explain how you created the 3DSketch1 on surface splines? I cannot figure out what feature they are on edge to.
I admit - the part's a bit of a confusing mess! A number of early features are children of later features which makes it difficult to follow my method.
After creating Sketch1 and Sketch2 (the top and bottom circles of the part) I created the first revolved surface - Surface-Revolve1 - from Sketch6. I then created Sketch5 (Surface-Loft2 > Curve2 > Sketch5), which is a 2D sketch containing a spline. Assuming the part is divided into 20 equal sectors of 18° each, I then created Plane2 at 18° to Front Plane using Y-Axis as the second reference. I then copied the spline from Sketch5 into a new sketch - Sketch7.
I then created Curve2 by projecting Sketch5 onto Surface-Revolve1. I created Curve3 by projecting Sketch7 onto Surface-Revolve1.
So at that point I had the top and bottom circles (Sketch1 and Sketch2) and the two curves (Curve2 and Curve3) on the surface of the revolve. To make 3DSketch1 I simply used the Convert Entities function and selected the two initial sketches and the two curves. Then I used the Trim tool to remove the excess lines.
I used Insert > Surface > Trim with the trim tool set as 3DSketch1 and "pieces to keep" as the area of Surface-Revolve1 enclosed by 3DSketch1.
Hope this makes some sense!
EDIT: Have a look at the SolidWorks feature called Part Reviewer (Tools > Part Reviewer) - it guides you through the construction of the model and allows you to see parent/child relationships.
Thanks, I see it now. I forgot that when new features absorb earlier features it sometimes makes the feature order look different than it really is and I wasn't paying attention to the new curvy parent/child arrows.
Here's my method. It's pretty straightforward - 3 sketch profiles and a center line for a surface loft, then a circular pattern.
