Loft rebuild Error
SOLIDWORKS Forums
6 months ago

Hi I am working on on molded shape.  I can loft the ellipses together OK but cannot loft them to an oval at the end constructed from lines and arcs.  
Any ideas how to fix this? 
Thanks.

Re: Loft rebuild Error

attach your file

Re: Loft rebuild Error

You selected 4 edges of your solid part...

 

The most robust modeling method is to show your sketch used to construct solid.

 

Or right click and use SelectionManager, but your loft will be tied to solid body edge and can cause future challenges.

 

Also strategically splitting the ellipse into four segments will help with the loft connectors.

Re: Loft rebuild Error

Did you create oval sketch or just select from your 3D model?

as Ruben suggested, please post your model here so other can try

Re: Loft rebuild Error

Did my above statements not answer your question?

The SW error explains what is wrong.

Re: Loft rebuild Error

I make it.

You extract the external profile?

Re: Loft rebuild Error

I have Solidworks basic, I am not seeing the same menus you show.  Does this only work in Solidworks Pro?

Re: Loft rebuild Error

Tim, Right click over Boss-Extrude4 and show the sketch, when lofting select the sketch and not the solid body.

 

The method Ruben is showing you adds another sketch, but you already have a sketch to use.

 

Less sketches and less feature create a more robust model (ie. make changes with less errors)

Re: Loft rebuild Error

I must be doing a step wrong. 
When I right click on Boss extrude 4 then the sketch icon, the loft icon disappears from the menu.

 

If I open loft first then click on Boss extrude 4, there is no sketch option.

Re: Loft rebuild Error

To Show sketch you must (twill down) the Boss Extrude feature first, and then Right click over the sketch and eyeball (=show)

The sketch will now be shown to add to your existing loft.
