Surfacing like doing a safety hard hat

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. blink.gif Hopefully to be enlightened with surfacing skills. Regards

Hi Joe

do you have specifi image of the hard hat you can share or is it just a common hard hat?

Hi Tom,

 

It is desirable that something like the real world rescue hard hat. Thanks.

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.

 

Regards.

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! mad.gif

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 sad.gif . 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.

Hi again smile.gif . 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 blush.gif

 

Almost getting there though. I plan to document the process as an exercise.

I was able to figure out how to use patch a surface on holes on the left and right side wink.gif . 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 blink.gif. Any suggestions or tip will be most welcomed.

 

Regards

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 smile.gif . 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 dry.gif yet.

 

Hope this also helps others wink.gif

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 sad.gif . 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. smile.gif

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.
