Solidworks Tutorial: Surface modelling a nose cone/domed surface
ฝัง
- เผยแพร่เมื่อ 29 ก.ย. 2018
- A tutorial that shows how to model a nose cone or domed surface using 4 sided boundary surfaces. This type of geometry is often modelled using 2 or 3 sided surfaces which results in singularities/collapsed edges which is not an ideal way of approaching this.
I've uploaded an updated version of this technique, you can view it here

This was such a great tutorial and an elegant solution to many surfacing issues my team has faced. Thank you so much for this!!
All good!
Great tutorial! This will definitely save me a lot of hours trying to figure it out by myself. Thank You
This is a great video. I fully went through from the beginning to end carefully and grabbed a lot of techniques. Thanks a lot.
You're very welcome!
This tutorial saves my life! I was feeling really frustrated as I don’t understand why I could offset the surface and now I know!
Great! I'm pleased it was useful.
Love this technique, hadn't quite seen it this way, will use in the future for sure. Thanks for sharing.
wow - where were you 2 years ago when I was trying to overcome the same challenges!
Im lucky making a nose on a uav right now and this saved me😂
Please do not delete this video.
I don’t plan to!
This helped soo soo much...thank youuu
Wonderful!
This video helped me a lot, thanks bro.
All good!
Dang, you’re good. Subbed.
brilliant
Excellent video. When you did have the end part of the dome to surface, instead of doing a surface trim to create a 4-sided shape & boundary surface, could you have done a surface fill instead? Thanks!
Yes, using a fill surface is always an option, but there can be downsides to using a fill surface, hence this technique.
Dear Andrew...what a fantastic video.....the way you demonstrated...simply superb...cover both for beginner's as well for advance...I have a drg.with me and the solid model for same drg prepared by my friend which is not able to help me now...can you help me at one stage I m stucked...REPLY ME PLEASE...
Hi there. Do you have a question about the tutorial? Or if it is about a work request please email me. Cheers.
Andrew, I assume this was a tutorial of how to use the "boundary" function. Is it possible to just use the "loft" function at the beginning and get the same results? If so it would seem to me a much easier approach with a lot less work, but I am only beginning my studies of surfacing.
Hi there. You can use boundary or loft to build this geometry, the fundamental thing this video demonstrates is to avoid making degenerate edges (singularities, collapsed edge) as I explain at the beginning. Loft is the same as boundary surface in regards to using 4 sided surfaces. You can use a surface fill with optimise unchecked (creates an overbuilt surface that is automatically trimmed) but there can be other issues that arise using surface fill. Here's some links with more info. Cheers

@@AndrewJacksonDesignStudio Andrew, Thanks for the kind reply and information.
Is it possible if we eliminate the hard edges altogether? (besides selecting the shaded view with no edges option)
During CNC fabrication, will the edges show?
The phantom edges are tangent. The only edges that’ll be visible on a machined item are G0 edges that form creases +
I'm able to follow up to 3:50 but when I attempt to create a solid it generates an error "cannot create solid. Use boundary surface feature." Any thoughts? Running SW 2018.
Hi, it sounds like you are adding a boundary solid feature rather than a boundary surface feature. You should use insert>surface>boundary surface. Thanks for checking out the tutorial.
Precisely the issue. Thanks!
Is there any reason why you wouldn't use a G2 or G3 surface condition over a G1 connection for this type of geometry?
Guess it depends on your design intent. Also, the dreaded SW wrinkles adjacent to boundaries.
Would it still have corner singularities if it was modeled full and not mirrored?
Yes, as you'd be modelling to a single smooth, closed boundary. An option would be to use fill surface with some constraint curves.
Im doing a similar thing but I want to convert to sheet metal afterwards. How do I do that? Do you have another video?
The surfaces are not developable - they are curved in both directions, so doubt you can convert to sheetmetal, with flattening. You can try the surface flatten feature if you need a flat pattern.
@@AndrewJacksonDesignStudio Brilliant, that worked. Thank you
@@HowdenDaniel Good stuff!
Hey Andrew, would this work:
a.) Trim this geometry in half; keep the nose portion, but delete the back.
b.) [boundary surf] the edge of the nose portion → to the sketched edge of the back
Ofcourse, you would have to make a "copy" of the sketch edge of back because it would be initially consumed.
Hi there. I'm not sure what the question is?
14:24 how did you make the piece green
Curvature analysis. help.solidworks.com/2019/english/SolidWorks/sldworks/c_curvature.htm
Just marking the steps for this method:
a. Final shape 4:09 using simple boundary operation.
b. However, the actual problem 4:30. Need break part into 2 steps. Each step=4 edgers.
c. Breaking surface Part 1 7:51. Looks simple.
d. Breaking surface Part 2 10:09 The tip plus "trim back" with "3 edges".
.
How much do you you do this bleander 3.0
I don't currently use blender
Saftey foot were Steel TOE CAP die design
the convert entities command wont work for me
Make sure you are in a sketch or 3d sketch first
@@AndrewJacksonDesignStudio ive been trying that and it isnt working. im trying to model a lid for a travel mug for my school project and its doing my head in. could i please send you a picture of the lid and would you suggest some commands to model it with?
@@Rob-sp3xv sure, send a sketch through to my email and I can draw a patch layout over the top. Cheers.
WHY do guys like this seem to like to impress viewers with how fast they do things, for 35 years I have seen the same thing over and over. SLOW DOWN!!!
Apologies, not trying to impress anyone with modelling speed! Perhaps look elsewhere if you don’t like it as I’m sharing stuff and it’s free… I’m not going to change how I present.
It would have been easier to use filled surface
Always an option. Downsides are : loosing some control - having a surface that may be trimmed on every boundary - sometimes looser tangency tolerance on edge conditions - not being able to use selection manager. Also sometimes filled surface can go haywire and if this happens in a complex model, when the filled surface is high up the feature tree, it can be a pain to trouble shoot.
Why don't I see the pop-up (for constraints etc.); that's so weird. Great tutorial though.
Might be an option somewhere to turn the pop up on and off?
@@AndrewJacksonDesignStudio I meant in your video, if you watch it you can see for example you are clicking where the horizontal vertical pop up supposed to be, somehow it's not showing up in your screen.
@@AndrewJacksonDesignStudio check around 0:39 for example
Oh yeah, I see what you mean! This was one of my first videos, maybe the screen capture was set to the SW window and it ignored pop ups.
@@AndrewJacksonDesignStudio ha that makes sense, all good!
