jolizon590016 Posted July 12, 2013 Share Posted July 12, 2013 (edited) Hi. I just like to know if there is a way learning to do this. I am trying to reconcile Matt Lombard's SW surfacing and complex shape modeling bible with IronCAD foolishly. Hopefully to be enlightened with surfacing skills.

jolizon590016 Posted August 12, 2013 Author Share Posted August 12, 2013 Hi Tom, Update on my end. I have attached a sketch and reference. I also explored the technique from Sudhir Gill's http://grabcad.com/questions/tutorial-mode...t-in-solidworks. The ellipse from the catalog is useful at this stage. My file is still a work in progress and I am stumped cause I cannot connect the 2 surface. I haven't discovered a work around it.

jolizon590016 Posted August 13, 2013 Author Share Posted August 13, 2013 (edited) I have updated the file with better construction but still have not connected the surfaces Ahardhat_4.ics Edited August 13, 2013 by jolizon590016 Quote Link to comment Share on other sites More sharing options...
IronKevin Posted August 13, 2013 Share Posted August 13, 2013 Try a 2 Guide Sweep to create the middle section of the helmet. Quote Link to comment Share on other sites More sharing options...
cborer Posted August 13, 2013 Share Posted August 13, 2013 In this case a two guide sweep surface with continius tangential connection to next surfaces would be nice! Or a new surface type called "tangent surface to connected surfaces, at border" Quote Link to comment Share on other sites More sharing options...
jolizon590016 Posted August 13, 2013 Author Share Posted August 13, 2013 Thanks Kevin and Carlo for your inputs. I give it a try and see if I manage to create the smooth flow. Quote Link to comment Share on other sites More sharing options...

cborer Posted August 14, 2013 Share Posted August 14, 2013 I tried to play that through for some minutes. I tried to make a guided loft shape ...a nightmare.... Many missing updates that I asked for ....years ago The 2 round curves: Merge for the 2 curves does not work (The Loft tool accepts only one of the curves also when merge) - We need a "real merge" tool! View of 3d curve not precise, when zoom in you do not see if it connects or not. No view for knots Split of the upper curve in 2 curves does not work Reset of Start and Endpoint of a curve not implemented Split Tool accepts only one curve as tool (would be nice 2) Try it in Rhino!

jolizon590016 Posted August 14, 2013 Author Share Posted August 14, 2013 (edited) Apologies if my learning exercise led to too much frustration. I do wish IC does make way as it seems easier to control the loft with v1.4 By the way just to mention this, there used an old Japanese magazine: Car Styling that also provided software insights and technique guides to surfacing. It feature Shade that was really interesting: http://mirye.net/. The interface as I recall is more intuitive than Blender (no pun). /Regards Carlo Going back to the loft control: I was more familiar with the guide curve of v1.4 but with the current version to correct it you have to use the right click editing loft shapes and select the create a 3d guide curve. I think this my error and humbled back since my mindset from Trispectives to 1.4 failed to jump to 2013 . The IRONCAD help really needs to be on the concurrent version to avoid confusion. Imagine a new user trying to reference help on a single screen as I find it already frustrating with my one of my dual display is dedicated to the IC help screen with progressive eye glasses. It was just recent that I have a dual display with the same resolution. Last time I had a 21.7 1080p as my main and 19 1440 x 900 that drove eyes like crazy because of the font scaling.

dhovatter Posted August 15, 2013 Share Posted August 15, 2013 zoom in on the smaller fonts. Hold "CTL+ALT" and roll the mouse wheel. I need to do that on my smaller screen. works on most things. Dallas Quote Link to comment Share on other sites More sharing options...
jolizon590016 Posted August 17, 2013 Author Share Posted August 17, 2013 (edited) Hi again . I reconstructed the model using solids: lofting and extrude and boolean union. Then extract surface. There some holes that I can't patch as a clean surface. Any inputs will help Almost getting there though. I plan to document the process as an exercise.

jolizon590016 Posted August 22, 2013 Author Share Posted August 22, 2013 I was able to figure out how to use patch a surface on holes on the left and right side . Before the patch was a concave, but by selecting the curve and using the surface as a part resolve it. What is left to solve is the front and rear holes which require a different workaround to patch it. I place a 3D curve on edge line on the center of the front hole but didn't work to close and follow the overall surface . Any suggestions or tip will be most welcomed.

jolizon590016 Posted August 23, 2013 Author Share Posted August 23, 2013 I have solved the holes in the front and back of the model. I merge the curves first and able to patch by selecting the merge curves and selecting the surface as the part . Almost finished trying to merge all surfaces as one, but as trimmed surfaces it doesn't allow me to do so. I tried to extract it as a new surface but didn't show the window merge it as one yet. Hope this also helps others Bhardhat_9.ics Quote Link to comment Share on other sites More sharing options...
jolizon590016 Posted September 5, 2013 Author Share Posted September 5, 2013 I have created a different work around, trying to have a smoother surface. I lofted 5 sections but the loft twist on the 4th and fifth sections. As a note the fifth section is a ellipse and the prior sections are splines. Created a new guide curve but won't follow through . With V1.4, I usually increase the facet rendering to resolve similar encountered problems. What I did this time is to loft the sections in half instead as a whole, copy and mirrored the parts. Extracted the surface from the solid created. If there are better work around, please advise and share. Dhardhat_5.ics Quote Link to comment Share on other sites More sharing options...

Guest EFOY Posted February 5, 2014 Share Posted February 5, 2014 (edited) Here's my typical approach to this kind of problem... took me about 35 minutes. The bill needs to be shortened some, and the ridge parts could use some additional massaging, but other than that it's not too far off. Method: 1. make solids 2. add, subtract, and blend 3. shell 4. add final touches. hard_hat.ics Edited February 5, 2014 by EFOY Quote Link to comment Share on other sites More sharing options...
