Split, Loft... help!

[bmiller1156]

This is my first post. I am new to inventor 2010 and this drawing is driving me crazy. I have searched this site and all over the web, but I don't seem to be finding an answer.

Very remedial problem. I have attached a picture of what I am trying to acomplish. I can make the 2D part no problem. I then extrude to 35mm. Now, how do I acomplish the angled surface? I have tried to split but I need to be able to measure the line height on each side of the part to acomplish the split correctly. Work planes don't seem to allow me to measure either.

I am sorry that this is such an easy problem. I can't believe what some of you all are doing with inventor on this site. Amazing.

Any help would be appricated.

As you probably suspected this is a trivially easy part.

Attach what you have completed so far and I'll show you the solution.

 

Assuming you modeled with a hexagon sketch (with horizontal line at top and bottom) on the xy plane and extruded 35mm -

 

Start a new sketch on the yz plane. Project Geometry the top top horizontal edge. Project Geometry the bottom bottom horizontal edge.

 

This will create two projected points on your sketch. Sketch vertical line at bottom bottom projected point and dimension 15mm. Connect the remaining point with a line and then exit sketch.

Select the Split command and change the option to split part.

Select the line as the split tool and the the side (top) to trim away.

For some reason I thought it would be easier in Inventor.

 

In AutoCAD it was make the two required profiles, use Region on them, Subtract one from the other and Extrude. Create a surface (at proper angle) then use the Slice command with the Surface option. Fairly involved. Result:

In Inventor two sketches (profiles). (no regions needed - Inventor allows mix and match of picking enclosed areas without creating polylines (which are non-existant) or regions - similar to AutoCAD presspull except allows multiple picks (not needed for this problem))

One Extrude.

One Split (slice).

OK. Seems much simpler when I read it now. Thanks.

JD Thanks this helped. I've attached what I ended up with. I ended up using my dimension lines to anchor the points. I've only been using inventor for about three weeks so I run across a lot of little things like this.

Thanks to everyone for the help!

Almost identical to AutoCAD except that I parametrically tied the two sketches together (Project Geometry) so that any change of any of the dimensions will cause the part to automatically update.

Would you say then that Inventor's approach is more intuitive thereby making it easier to construct this type of geometry than AutoCAD's approach?

Its much easier to alter it down the line if needed. The approach can be the same between the two software packages. You can draw a side profile, cut-extrude it, draw a surface, thicken cut. use a plane and so on.

 

For this object I drew the original profile, extruded. created a plane based on the top face and an angle(will update if your extrude height changes). Then i used the sculpt button to use the work plane as the new face.

I really have to try Inventor out although my job would never call for actually buying the software or trading in AutoCAD for it. Per comments made by JDM though I'd be worried that my "mindset" would be so AutoCAD ingrained that I might become frustrated trying to use the program.

in the help section there is a special set for users coming from autocad:)

 

I think the biggest thing you would have to overcome is no command line:)

 

Per the Region thing. When you have a closed profile in a sketch, once you exit the sketch and try to use it, its easily selectable. Inventor is really good about having multiple closed sketches and letting you choose one, some or all of them. You still approach the model in the same way you would in autocad but it gets adjusted a bit for the tools you have available.

"in the help section there is a special set for users coming from autocad"

 

I assume I'll recognize this help section because it will be labeled: Over here stupid!

 

No command line? OMG!

 

I have a feeling this is going to be a lot like being taught to swim by my father when he threw me off the end of the dock into water way over my head. Keep paddling son...you're doing just fine!

'Intuition' comes with experience. Now I've been using Inventor for a while I find it much easier to use than Autocad. The clincher is when it comes to creating drawings. I still haven't got over the novelty of it!

Hello there.

I haven't had a look at the files attached on this thread, but is it just me that's confused? I feel it's a confusing drawing, because what it's trying to illustrate can be misleading as all dimensions detailing the cutout in the middle is done on the slanted plane, and that shows the true length of the notch width to 12, hence if you wanted the 4 notches to be 12 as shown, two will be 12 wide, and two will be less than 12 ...

I'm assuming that the hole in the centre has all 4 slots symetrical, 12mm wide and 60mm across flat to flat, not true length distances.

Regards,

David

I agree with you David. It does seem a bit odd.
