Bertadesign Posted November 28, 2022 Share Posted November 28, 2022 Hello everybody, I'm trying to build ribbon and bows for a gift visualisation but got stuck. Any advice? I'm attaching a couple of images here for further details. Any links to videos alos very much appreciated. Thank you! Quote Link to comment
Kevin Allen Posted November 28, 2022 Share Posted November 28, 2022 looks like a complex assembly of NURBS objects, mostly Lofts. I would say that just because the ribbon is one object IRL, it likely needs to be modeled as separate pieces. 1 Quote Link to comment
Pat Stanford Posted November 28, 2022 Share Posted November 28, 2022 Probably achievable in VW, but not what it is really intended for. I could not find anything like this in the Sketchup Wareshouse. Do you really need this to be 3D or could you get by with some imported pictures and make Image Props from them? Or even Image Props of the complete packages? Quote Link to comment

I've also done things that were hand sculpted and/or thermoplastics and that could be done from references and hand doodles. Typically clients cannot any longer make the leap from doodles to finished product, they need to see a rendered model. Quote Link to comment
Mark Aceto Posted November 29, 2022 Share Posted November 29, 2022 6 great instructional videos about NURBS (that I come back to whenever I need a refresher): https://www.youtube.com/@jBenghiatLD/videos 1 Quote Link to comment
Bertadesign Posted November 29, 2022 Author Share Posted November 29, 2022 Thanks eveybody. I will look at these videos! @Mark Aceto @Pat Stanford I wondered about this too but agree with @Kevin Allen that the more realistic the better for the collaborators. But if I went down the route with the image prop, what would I have to do? Have a png with the bow cropped and a transparent background? 1 Quote Link to comment
Mark Aceto Posted November 29, 2022 Share Posted November 29, 2022 This is also kind of the perfect way to learn SubD because your'e not trying to recreate a perfect model of a Lamborghini. It's a totally freeform organic sculpture with no right or wrong. You're not snapping to or aligning anything. You can just pull at it like taffy until you've roughed it in. Josh has a great SubD video at the same link (his YouTube page), and @Luis M Ruizhas some great videos in VW University. Also, because it's a SDK that was released by Pixar, most SubD tutorials on YouTube apply (same principles; similar tools and workflows). The only caveat is at the very end of your modeling, duplicate it, and convert to Generic Solids for texture mapping. Keep the original model in case you want to make edits. We've been requesting that SubD get proper texture mapping for years but it keeps falling on deaf ears. 2 Quote Link to comment
Pat Stanford Posted November 29, 2022 Share Posted November 29, 2022 Using the bow from your first post. Here is a very quick sample. I made an image prop of the PNG. Used the image to make a mask (had to adjust the contrast). The Box is an extrude. In the lower image I chamfered the edges. The ribbon across the package are 2D rectangles on working planes. I used the eyedropper in the Color Palette to pull the color off the bow image. The bow is at the side because that is the way to get the dangling ends to show. From start to finish about 15 minutes, including writing this post and finding the textures I wanted to use. The first image is Shaded, with low quality. The second image is Shaded with a light source added and everything turned up to very high. 1 Quote Link to comment
