We have an assembly that is going to need a heat shield.
Is it possible to say, 'create a surface that is at least 10mm off from assembly', and then trim and thicken to suit?
Yes there can be several ways:
1. Start a new part in context of assembly OR insert a new blank part. Now offset from the external faces with required distance and then thicken to suit.
2. Start a new part in context of assembly and draw a block big enough to cover the assembly OR insert a new part having a block feature. Now use cavity feature (this is available when you edit a part in assembly) and subtract the assembly components to get the shell. Add/remove thickness as needed.
You would have to pick the methods based on the complexity of the assy.
I'm trying to add a file for you to show me what you mean, but I cannot seem to see anywhere I can add files, only pictures. There's no link for advanced editor. Has something changed? I'll attached a photo, and hopefully you can still help.
Basically, I cannot seem to get the system to allow me to cavity an assembly. I almost want to create a curvature of the outer edge.
Imagine you were going to create a cover, 10mm from the top edge i.e. this is surface mount, and it to curve to suit (not be ridgid). This will be a vacuum formed item.
Check #18 of Forum Posting on how to attach files while replying to a post.
Other option would be to save assembly as part with exterior faces only option.
No places suggesting attach files. I can get to the advanced editor on other threads...
I can see it so some glitch on your side
Anyway, edit your first post and see if you can attach files in that.
For some reason the forum posts can be seen in two different formats, one is through the your inbox and that shows different then coming in from the "Home" or "All Content" tab.
You can also get there by double clicking on the topic header, this will show a different reply page
It appears that trying to reply from your inbox won't allow file attachment. Must be some malware protective process.
Anyway, I can now attache, butI have moved on from this. I spoke with our support team, not really a goer for offset surfaces. Too many bodies.
However, I created a 3D sketch from assy, then extruded a surface from that. However, I cannot create a flat pattern. I cannot see why not.
Yes Martin, there is a Santa Claus... sorry
Add a new component to your assy and then grab some edges or surfaces from the assy while in the new part. Then open the new part and start your modeling.
This is what I did in the end. However, I cannot get the part to flatten in sheet metal. Apparently you don't get the 'flatten surface' tool unless you have premium - SW butt wipes at it again...
Any ideas why this part won't flatten. I used this approach in Inventor many times.
made a dxf file then base flange
Would that still be linked with the original curve, or would this be now seperate?
Sorry I can't see it, I'm on SW2015.
Why not just offset a sketch and add the base flange there instead of a surface offset, thicken and delete face??
no it isn't but I do believe this one is
like John said offset sketch. John when I tried that it doesn't like that spline for some reason. so did it with the loft.
Sheet metal & spline don't work so well
See the video that I posted here:
Trying to enclose a part with an external boundary layer
Edit: You should be able to do the same thing, except with your final part, add it to the assembly instead of adding it to the original part.
Yes, there are a lot of tools that don't like each other on here.
I remember trying to model a 150x50 channel up the edge of a curved staircase a few years back. It took me 2 days to find a way to stop it from twisting, whilst avoiding splines as a guide rail.
Who does the Beta testing for this software? I must be trying to use the software outside if it's remit. Otherwise, why is so difficult to do such simple things?
Yes, Solidworks is not a fan of splines.
I had to convert the spline so I could create a surface. However, if I thicken a surface it should automatically be flatten..able...
Now I have to create another sketch completely.
Step one: draw circle on wall.
Step two: bang head repeatedly until this makes sense.
If step two fails; Step 3: assume the fetal position and suck thumb..
Using SW isn't difficult -
"If" you know what each feature is for and what each feature does, plus lack of training or improper training can't put anybody in a difficult situation, been there done that....
I was just talking to our support team, and they were having trouble with this one.
SW isn't difficult. Inventor is the same: it's like getting used to having an arm amputated. Sure it's not as easy as having two arms, but you find a way round it...
Martin for your offset try this the 3 boss extrude are just hidden offset is driven off of those
This was one of the methods discussed with the support team. However, there are about 1000 odd surfaces. It may take an eternity to get that one down this way.
The cover ends up looking a bit like this. Although the offset part is proving to be a bit more difficult than originally thought
I had to create a 3D sketch within the assembly. Create curved points, extrude the surface, and thicken. Although this will be impossible to flatten
Keep in mind how it will be manufactured, you could get that shape using a Stamping operation, however if the part is done using Air Bending (Press Brake) then you'll never get close to that shape. If you plan to have it made with a press brake, then I would design it around that process..
You're preaching to the choir, John. I've said it would be easier to have square corners, but they want a 'dynamic' shape. I'm not pulling the strings.
I'm guessing it will be either stamped/pressed or 3D printed (DMLS - sintering). It will be Aluminium.
