CAD tutorial

[BoilermakerFan]

Will do, but it's very rough. The door is not the right size or shape. No child's bunk, axle, etc.

Hey BoilerMakerFan...

You've done a good job modeling so far... but why did you stop? We need to see hatches, and beds, and a bunk bed, and pillows, and curtains, and pots and pans, and and and...

But okay, here it is, for those of you who have Cortona installed!!!

P.S. If you need the Cortona client to view the VRML (wrl) file above, you can download the free MS Internet Explorer addin here...

I did that over my lunch hour. I'm ready for the rest of the tutorial now!

How do you get Corona to zoom out? The TD is really zoomed in and off center.

 

[mikeschn]

There is a "fit" button in the lower right hand corner...

First hit fit, and then hit "study"!

I thought that was the whole tutorial... was there something I didn't teach you? Oh yea... the bed...

1) Drag out a block
2) Select Intellishape
3) Right click on block, and change the sizebox to 80x60x4

Add the correct texture, and place it inside!!!

Mike...

P.S. Seriously though, is there something I missed?

 

[BoilermakerFan]

Thanks.

Now all I need are CF and Kevlar textures!

The easy way to do the axle, wheels, and tires.

The easiest way to open the galley hatch.

Tips on a/c, heater, keg, stove, cooler...

Sorry, there is no easy way... the best thing you can do is grab a keg, or a stove, or a cooler, measure it, and then model it. A simple wheel would be a black torus with a silver disc in the middle. The axle can be a piece of square tube running inbetween the two wheels, to represent a torsion axle.

Here's a photo of the wheels I was thinking about...

Oh, and for the hatch... subtract out a block where the hatch is going to be, and then build a hatch! Building a hatch is as easy as building the door was!!!

Mike...

 

[BoilermakerFan]

Now I see why guys just start building!

 

[mikeschn]

Exactly... it took quite a while to model the square weekender...

I built the mockup for it in a morning!!!

Today's Top Tip - Fit a wall on the left side, otherwise everything will fall out on the road...

Oh, and for the hatch... subtract out a block where the hatch is going to be, and then build a hatch!

Can't you be a bit more cunning? For example:
-copy the body off to one side
-create a block where the hatch will be
-copy the block off to one side
-subtract the block from the body to make the hatch cut-out
-use an intersection between the body copy and the block copy to make a hatch
-move or copy the hatch back to its position in the body

Make sense?

Andrew,

Sounds like you're a natural born solid modeler... just use separate layers instead of moving block and bodies off to the side, and it'll be perfect!!!

So can we expect some wrl files from you soon?

Mike...

 

[mikeschn]

Brian,

I played with your file for a few minutes... I put a piece of glass on the left side so you wouldn't lose the contents of your trailer... per Andrew's suggestion...

I also stuck the weekender cabinets in there... They don't work well with the size and shape of your teardrop, but it gives you something to look at!

Go go ahead and give it a whirl (right Bev?)

P.S. I made the door on the street side bigger too... it's now 30"x48".

 

[BoilermakerFan]

Thanks Andrew.

I didn't put the street side wall on it to show off the Burl Maple interior!

I'll be reconstructing the doors later. Adding the tongue box, galley, environmental control unit (nope, not a commercial unit), keg, etc.

The basic TD is very easy to make and I wanted to get it posted in this thread to encourage others to give a whirl too!

-use an intersection between the body copy and the block copy to make a hatch
Andrew

I just found out IronCAD doesn't have a boolean intersect command, which doesn't make sense, since it's part of the parasolid kernel. :

So I ended up taking a copy of the body with the block already subtracted for the hatch, and subtracting that from the copy of the body, to get the hatch. Whew! Make sense?

Yup, it pays to be able to think a bit laterally when manipulating solids.

No, but I appreciate you sending me the modified file. Haven't had a chance to do anymore CAD work. Hopefully I'll have a chance this weekend.

Dear Mike,

Wherz the tutorial pdf?

 

[mikeschn]

It's here...
