Swept Boss not working

Hi Muhammad,

It's really hard to tell from just the image, but two things I noticed.

1) The icon you've circled looks to me like the 'revolve' icon?

2) Maybe it's my eyesight, but your circle sketch doesn't look like it's on the right plane (to the helix) to be able to be used as a sweep profile. Having said that, you don't really need a circular sketch to do a round sweep along the helix, just select circular profile in the sweep property manager............

Can you attach your part?

Dave.

Create workplane perpendicular to the start of the Helix.

Create circle sketch fully constrained to the start of the Helix.

Are you a student?

Hello,

In addition to Mr. Bear's reply, the circle diameter is large relative to the helix pitch.

This will generate self-intersecting geometry. SolidWorks permits this, but why?

Mr. Bear,

I believe it is a Sweep icon, but from a previous SW vintage. My SW2018 is this:

But the 180° icon looks familiar.

Hi Muhammad,

Which version of SW are you using? The icon you have shown is SW 2015 and below.

Some rules below (SW2015) for the Sweep feature

     Sweep creates a base, boss, cut, or surface by moving a profile (section) along a path, according to these rules:

• The profile must be closed for a base or boss sweep feature; the profile may be open or closed for a surface sweep feature.
• The path may be open or closed.
• The path may be a set of sketched curves contained in one sketch, a curve, or a set of model edges.
• The path must intersect the plane of the profile.
• Neither the section, the path, nor the resulting solid can be self-intersecting.
• The guide curve must be coincident with the profile or with a point in the profile sketch.

Can be found here -

2015 SOLIDWORKS Help - Sweeps

and all the way back here - 2012 SOLIDWORKS Help - Sweep Overview

Looking at your image it looks like, as pointed out by Kevin, the result will be self-intersecting. This is not possible in the older versions of SW.

It also looks as if your sketch plane maybe off, as mentions by Dave.

Try to setup your sketch as shown below.

Hope this helps in some way.

Attach your file here.

Can you ask your instructor to join this discussion?

And you are still editing the Sketch3... You have to leave / close the Sketch first. Afterwards SWX will find the 2 Sketches/Curves.

But yes: The circle seems to be not perpendicular and to large...

Just curious............

Given the nature of the question here, and the new one you just posted which is Sketch of a Model, I have to ask if you have done any of the tutorials that are built into your SolidWorks software? You will learn a great deal by doing them and very quickly.

Dave.

Get out of the sketch3 and then it'll work.
