AlbaLLI Posted November 5, 2018 Share Posted November 5, 2018 I need to model a bath as per the below image, please see below: Copenhagen-Bath_specifications_Venø-bathtub-40030005.pdf Could you please let me know which 3D tool is best to use? Quote Link to comment
Kevin McAllister Posted November 6, 2018 Share Posted November 6, 2018 Here's an example of how I might approach it. Note that it doesn't take into account the sloped bottom of the bathtub. Here are the steps in the attached file - A) Create the curves for the various levels of the bathtub. I traced them off the PDF which I brought in and scaled. B) Convert some of the curves to NURBS and move them into their 3d positions. I also created a simple extrude from one of the curves for subtraction later and added two linear NURBS curves for guiding the lofts. C) Loft the interior and exterior shapes using the birail sweep mode (3rd mode) of the Loft tool. Select the two rails and the straight profile curve for each loft. Make sure the create solid checkbox is selected. D) Subtract the extrude and the inside loft from the main tub solid. E) Add fillets. Ungroup the model to see the three fillet steps I added. Add additional details as needed. Kevin Bathtub.vwx 4 Quote Link to comment
twk Posted November 6, 2018 Share Posted November 6, 2018 Couldn't help having a go at this one! Similar to Kevin's approach. Initial loft was created from 3 nurbs curves, mapping levels of exterior bath (top, bottom, bottom of outlet) in provide PDF section. Scaled and adapted to fit. - from solid generated, shell solid was then generated, then chamfered relevant edges - second part was the base, reusing to nurbs curves from step 1, then using the push and pull tool to adjust the heights to match the section height of the base(did this as the push and pull can follow then slope of the solid using the second mode). - then subtracted internally, then joined to main bath ModelBath.vwx 4 Quote Link to comment

I love seeing how different people approach a geometry problem. I think all the solutions to create the sloped bottom require making the tub in two pieces. I think I might re-align the seam when lofting the main tub so that the isocurves are a little cleaner for the sloped portion (bottom tub in the image). The VW interface for aligning them is not great but its a little easier if you Loft in top/plan. Kevin 4 Quote Link to comment

Jonzr Posted March 15, 2021 Share Posted March 15, 2021 Excellent post! I am spending a few days learning how to create a clawfoot tub in 3D. Any suggestions???https://www.google.com/search?q=clawfoot+tub&rlz=1C1EJFC_enUS813US813&sxsrf=ALeKk02z57OB-lXfumR_RFvUAtsX_g-bnQ:1615846201928&source=lnms&tbm=isch&biw=1920&bih=969#imgrc=3RqdALmvzbQ1AM Quote Link to comment
Kevin K Posted March 17, 2021 Share Posted March 17, 2021 @Jonzr Yes, I do have a suggestion.....!! Don't bother....just buy one already modeled ! :-) Do note that in Open GL you will not see reflections, etc. It would be a bit of work with the available VW tools to create the claw feet. Enjoy your bath!! :-) SLIPPER TUB v2020.vwx Quote Link to comment
Jonzr Posted March 17, 2021 Share Posted March 17, 2021 Of course I had considered this, but it gets pricey. And, of course, I'd like to know how to draft more complex 3D shapes. Thanks. Quote Link to comment
Kevin K Posted March 18, 2021 Share Posted March 18, 2021 You are welcome. Of course you should proceed with your 3d modeling skills. I merely stated that VW is not really set up, nor does it have the tools, that other software offers that specializes in creating complex and organic shapes. Quote Link to comment
Popular Post AlanW Posted March 18, 2021 Popular Post Share Posted March 18, 2021 (edited) Hi, This is a quick bath and claw foot using Vectorworks. Subdivision mirror mode for feet and shell solid and distort tool for the bath this all took only a few minutes. HTH How do you link a video here now?? you used to be able to add link. Want to add one to show how simple it is to do this bath. Edited March 18, 2021 by AlanW 6 Quote Link to comment
Benson Shaw Posted March 20, 2021 Share Posted March 20, 2021 OK - Really cool approaches, everyone! I didn't directly address @AlbaLLI 's tub, but wanted to explore the "classic" iron clawfoot tubs (ya'know, those based on upside down shape of the old Porches), especially representing the rolled over edges. I think the drainage can be handled in a number of ways, but for me the easiest is modeling the bottom, as @Kevin McAllister points out, as a separate form, then combining and filleting with "walls" of the tub. Love @AlanW's fast tub. I messed around with both single rail lofts and BiRail sweep. Birail is probably better choice. Both accepted a Fillet Surface (3d Power Pack) but then would not Add Solids for final one piece form. Also, the bottom needed to be formed from extracted edge of the tub, rather than the initial rail curve. I think vwx faceting might be an issue with that. Fortunately, Edge Fillet worked. Mine is a fictional tub. Lots more to be done to match the various products out there. Still thinking about the feet. Just don't ask me to do acanthus decoration! -B Tub v2021.vwx 4 Quote Link to comment

Jonzr Posted March 21, 2021 Share Posted March 21, 2021 Holy cow. How did you learn to do this? Seriously. I have so many Youtube videos on so many different approaches to 3D modeling, but this piecemeal approach is not helping me at all. There seem to be multiple solutions to this, but yours looks very clear. I don't need the extra contours you added, but it looks like something I could attempt. Thank you! What I need is a book. "How to Model 3D in Vectorworks." Quote Link to comment
AlanW Posted March 21, 2021 Share Posted March 21, 2021 (edited) @JonzrHi, I learn as much as i can about any program i am using, that way i have more ideas to choose from when i need to solve things. Just play with different tools to see what they do. https://www.youtube.com/watch?v=aXii3iHDsQM Here is another way to do the bath and is useful for a lot of other things. Revolve with rail. The section shape follows any plan shape. try different shapes to see the result. Edited March 21, 2021 by AlanW 1 Quote Link to comment
