Welcome to my RU-vid channel dedicated to Solidworks and Rhino modelling techniques, primarily for industrial designers. I share practical tips, problem-solving strategies and tutorials to help you overcome challenges in Solidworks. I also share techniques I have used in real-world projects, hopefully providing inspiration for your own modeling techniques. Thanks for watching and happy modelling. AJ
Hi Andrew, Thank you for sharing this knowledge and also the file to dig more deeply into the details. :-) I'm still working on my Donzi 16 boat and this gives me some ideas about how to get the stability rails (chines) to blend better into the overall hull shape. I'm presently getting a lot of wobble where the hull's boundary surface meets the 'spline on surface' extrusions I used to make the stability rails. Quick question: what works best for you to look at Solidworks models in Rhino? -I'm not sure what's the best file format to save as from Solidworks. I feel silly for not being able to suss this out for myself, but I'm new at all of this is my excuse, I guess. I'm having pints on Fridays with a German gentleman who's a wizard at Rhino and I'm hoping to share my Solidworks trials & tribulations with him in a format he can view in Rhino. Thanks again for sharing the fruits of your labours!! 🙂
Hi Matt, I mainly use Step 214 to export to Rhino. There are some options in the SW export settings which you may want to change, depending on whether you want SW to export curves as well. Hope that helps and thanks for watching! Cheers, Andrew
Please, how did you align the reference 3D scan. A workflow, I have in my head is to create new "primary" planes based on the geometry symmetry and prominent surfaces, then export with a new coordinate system based on this new "primary" planes, and then reimport... Would that work?
Hi there. I re-positioned and rotated the scan data to where I wanted it in Rhino. Much easier than in SW. Off the top of my head, what you mention should work though.
I find that this technique only works (in terms of achieving good surface continuity) if the sides of the nose cone are perpendicular to the right plane. As soon as I add draft (3 degrees) the surface continuity falls over completely. Perhaps I am doing something wrong here? Anyone else had this experience? I'm going to try and add a ribbon surface to assist with tangency/3-degrees and see what results I get. But I find that this technique is a struggle in a lot of CAD packages when you add draft.
That is strange. I use this technique frequently to cap off corners and other areas where the primary surfaces leave a 2/3 sided hole. Here's a few videos where I have used this technique, except with a G0 boundary (same as the G1 centre line boundary the RH plane you mention in the nose cone). I guess the difference is in these videos, I do not use a ribbon to explicity define a draft angle on the G0 boundary. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-mC2uhPYScY8.htmlsi=hbTqTQocL5-ASEKW ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-yontOO7J3Io.htmlsi=NLhpusdbq2Lr5zBq Ruled surface can be used to make a ribbon, but sometimes the result can be a little average. I've had some success using an extruded 3D sketch (with draft) to make a ribbon surface, or if you don't mind a little variation in the draft, a loft, using two profile curves made in a 3D sketch, tangent to the relevant geometry, then a single edge/curve as the guide. If you are using a boundary surface to make the final patch surface, try playing around with the tangent influence a bit, as some times having 100% in the first direction and 0% in the second direction works, or vice versa where that creates ripples near the boundary.
Thanks Andrew. I’d love to see how you go about “propper” top-down referencing in SolidWorks. Coming from Creo that has a really robust “published geom” (copy surfaces, lines, datums etc), what’s the equivalent in SolidWorks that you use? I find the technique of breaking parts out of a multi-body master part to be very unstable and frequently leads to issues in larger, more complex assemblies. Is this what you use or something different? Would be great to hear your thoughts, as well as any tips and tricks you would throw in/recommend. Thanks again for these great videos!
Very much agree, that an interesting topic of SW surface modeling. When to switch to solid ? mid part, copy surfaces to make temp solid and check volume for example or are there other ways to handle surface/solid rebuild stability issues ? Andrew, your thoughts would be highly welcome !
I only use 'insert part' for copying geometry into other parts. You can copy surfaces, solids, ref geometry etc. I guess with AAX/published geom it gets added into the master part file as a feature, so you dictate at which point geometry is captured and published? The problem with insert part is it just copies over whatever is left at the bottom of the master part feature tree, so if a surface body is referenced, then someone adds a fillet to the surface body, that fillet geometry gets sucked into the child parts, whether it is needed or not. Ways around this is to make a copy of the geometry that is to be referenced, further up the tree, then make sure it does not get cleaned up with a delete/keep body feature at the end of the model. This might sound weird, but I have worked on a master where it effectively needed a branch/fork with some deviations in the geometry that was being referenced. Be way easier if you can pick the geometry to be referenced at discrete points in the tree!
@@AndrewJacksonDesignStudio what about Save Bodies? then it saves only the part that you want. Ive done this with different configurations too. I also like Insert part when I want to import more info.
The downside to save bodies is it does not take any reference data with it which is why I use insert part. I guess you could create planar surfaces to act as planes, edges as axes, etc, but then you'd have to be on top of documentation in a multi user environment so others understood what was what.
I've been struggling for longer than I'd care to admit trying to finish the bow section of the Donzi 16 (speed boat) I'm modelling. This tutorial has rescued my project and my sanity! Thank you!!
Hi, I love your content. You make great tutorials. Could you maybe make a video of general tips for surface modeling like what to avoid doing, which features are rather stable and which you shouldn’t use? There is little to no content of this nature on youtube, most of videos are simple tutorials that don’t show bigger picture like how to manage building complex parts so they dont brake on rebuilding. Cheers
Hi there, thanks for the suggestion. I can definitely see the value in a video that covers some of that. Might be some time away as my interests currently lie elsewhere.
I was using an Ipad Pro but that's a bit clunky to use on the trail. I now have an iPhone 12 Pro, which was the first with the lidar on the front. I use 3D scanner app, which seems pretty good so far. Lots of viewing options as well as export options, so you can make a video within the app, or export it into other applications, like I have done here with the ride-through animation. apps.apple.com/us/app/3d-scanner-app/
@@AndrewJacksonDesignStudio I can understand this happened once you get perfect geometry then you may repeat method while recording, because for beginners they face error.
Yes, understandable from a beginner point of view. I'm not producing beginner content as youtube is flooded with it. I try and capture more advanced techniques that I may have figured out on client jobs, or exercises that I have set myself to improve my modelling skills. I pretty much always upload the part file, so people can roll through it and pick it apart. Thanks for watching.
Always my go to for Solid works surfacing advice! I was wondering how you might attack a Logitech MX master mouse, I know design partners did a lot of the work for it and was curious what software they might have used when working on it. Cheers for the great videos
Hi Ollie, not sure how I'd approach that mouse off the top of my head. DesignPartners (now PA Consulting Ireland) did use Creo but I know they also use SW as well but suspect Logitech is still Creo. Thanks for watching!
Hi, I posted a STEP export of the primary surfaces in this forum thread. I'm not releasing anything more detailled sorry. cadforum.net/viewtopic.php?p=30055&hilit=747#p30055
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.
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".
Last I heard, Logitech still use Creo. When I was at Designpartners (now 20 years ago... feeling old) they designed quite a few of Logitech's products, all done in Wildfire at the time. Main exterior/offset surfaces handed over to Logitech ME dept (in Cork?) for ME modelling.
I am following the modeling using the 3D file you shared. Thank you very much. I think view of the sketch 126 was set separately. How did you set it up? Due to different sketch plane view settings, I could not passed at this stage. This part is not even shown in the video. I would really appreciate it if you could let me know.
Hi there. Sketch 126 uses Plane 40. Plane 40 references two points and is rotated via an angle reference. I have no control over how the view is oriented in 3D space, when looking normal to the sketch plane. Solidworks sets that based on the plane references. Plane 40 is directly above Sketch 126 in the feature tree, if you are using flat tree view, which it is in the model I made available online. The video is not a tutorial! It'd be hours long, that is not something I am interested in making. The model should suffice if you have an intermediate level understanding of Solidworks. Cheers.
Hi there. Good question. The main reason is nurbs surfaces have 4 sides, so if you make a boundary surface with 3 sides, one of the edges is collapsed into a singularity. That can cause all sorts of headaches later on (surface wiggles, issues offsetting surface etc). Surface Fill in Solidworks will fit a larger/overbuilt 4 sided surface patch over a 3 sided hole which is then trimmed. It can be difficult to get good edge continuity using surface fills (even with constraint curves) plus they can randomly 'blow up' with spikes, dimples and wobbles appearing for no obvious reasons. These links have some great information that is relevant to SW as well.

@@AndrewJacksonDesignStudio Thx man! Love your attitude. You are really helping me (and I'm sure also a lot of other people) out. Keep up the great content! As an industrial design student I only really learn solid modelling at university and its hard to get good tutorials for surface modelling in Solidworks. Btw I'd find it super interesting to hear where you see the weaknesses and strenghts of Solidworks in comparison to Rhino. Thats a discussion I often have with colleagues ;) For me the main reason why I choose Solidworks is the Feature Tree and the ease of making changes afterwards. On the other hand if you plan on working as a freelance industrial designer you have to pay way more money for using Solidworks than Rhino. Maybe you could cover that in a future video
All good, pleased the videos are helping. Yeah there is lots of solids/intermediate content out there but not too much surfacing, and half of the surfacing content is people making patterned vases or impossible tables, which has little value for ID'ers trying to use SW in a production environment! I use both Rhino and SW, but mainly SW for commercial projects unless I need a super clean/lightweight surface, in which case that is usually needed for Grasshopper for patterning etc. I find it much easier to make changes to models in SW, even models that are well developed and feature heavy. You do need to structure the master models and child parts accordingly to make them robust enough. The down side is SW output can be average, with the SW analysis tools being too clumsy to spot some wrinkles/issues with surfaces and edge continuity. I have a macro to push selected surfaces into Rhino to use the zebra analysis there, as you can control the analysis mesh much more than you can in SW. It is possible to make much cleaner/lightweight surfaces in Rhino, as well as being able to point edit the surfaces, which is not possible in SW without using the freeform etc features, which are not a joy to use. With Rhino you have to have a strategy in place to deal with changes, which in my case, means layering off the model as things progress, so you can always go back and branch off an earlier iteration. Hope that helps! Cheers, AJ
