I'm trying to understand the exact mechanism of "Swept" command.
As shown in the figure, a short line is used as Section and the right green curve string is used as the Guide. All the other options are defaults.
But unexpectedly the resulting surface is not of the shape as the green curves. It seems to be difficult to understand.
Can anybody kindly give some clues? Thanks!
Solved! Go to Solution.
now I cannot use CAD, I hope I will be able to show you how swept works with the attached image.
With the "rigid connection" in your images, the curved surface should occur at point A, not point B. Do I miss something else?
Hi, @Cesare, it seems that:
● Section Location: Anywhere along Guides
→ the "rigid connection" is always in the direction perpendicular to the guide tangent
● Section Location: End of Guides
→ the "rigid connection" is always in the direction from the section to the guide start
Is my understanding right?
In following two examples (Example Set A), I use a tilted circle as the section. Different "Section Locations" give different ends shape. When "Section Location" is set to "Anywhere along Guides", the resulting ends seem to be a surprise.
I'm sure you are confused, the Swept command is very 'complex'.
Look at how it behaves with different orientation options, in addition look at how the command menu changes depending on how many set of guides you choose.
Before using these commands, familiarize yourself with general concepts such as the common alignment concept with other FF comends.
Hi, @Cesare, thanks for your reply. I follow your suggestions and read the official page on Alignment methods carefully. It's very helpful to understand the general alignment concept of controlling how the feature flows from one section to another.
In my Example Set A (i just edited and numbered my posts before your latest reply), I still have one point to tackle:
The "Section Location" seems to play a decisive role in the process. I do want to understand how Swept works with the "Section Location".
In my Example Set B, two very similiar conditions give completely different results. It also seems to be related to the "Section Location". I doubt that Swept have some undertable mechanism to handle it.
Hope to have your comments.
