Sketching on a Curve

Sketching on a Curve

Hi,

 

I was looking on the forums, however, I couldn't reproduce what I saw in some of the examples. Maybe, they used a different version of Inventor. I'm using Inventor 2017 and I'm trying to project an image on a surface that isn't flat.

 

My steps were to draw a sketch on a plane. Then project it on a surface. However, I had to make it a 3D sketch, which will prevent me from extruding, since it must be a 2D sketch.

 

Now, I tried to use the split feature, like I saw in many examples, but none of them worked.

 

Thanks in advance.

Thanks for your reply!

 

I'm spending time learning Inventor as a hobby and with the surfacing, the freeform, and etc, I feel that I almost have all the skills needed to be a successful CAD modeler. The one valuable tool that I'm missing--is the ability to draw a sketch on the curve, which can have good applications when you need a particular pattern.

 

Here's a video from Solidworks. I was hoping that I can do the same steps, but using the Inventor options, to be able to extrude like this lady did.

Hi chrisbiz1e,

 

Have you tried the Emboss tool?

I hope this helps.
Best of luck to you in all of your Inventor pursuits,

your saying: project an image on a surface... but the YouTube link shows something else...? no image but some other stange way of constructing something.

I created a screencast of doing the same in Inventor.

 

so you can only sketch on a plane surface, but with a 3D sketch you can construct a 3D sketch of that planer sketch and the curved surface.

 

here is my screencast: http://autode.sk/2ohYPgD

Succes on your project, and have a nice day

Hi! I suspect you are looking for Curve on Surface. Create or edit a 3D Sketch -> Curve on Surface. Then you can draw on any face.

Many thanks!

Here's a more complex way of doing (2017 IPT). Move EOP from top to bottom for seeing the steps. 3DSketch2 is empty and can be deleted.

 

Question for Johnson: Why can't I add an angle in Ruled Surface1?

Another issue: Why is the edge zone of the boundary patch (red circle) distorted?

Extending this surface at the left changes direction, too.

Hi Walter,

 

BP is also another type of Freeform tool (non-Tspline). Basically, Inventor tries to fit a G2 continuous surface passing the selected boundary. In theory, the solution would not be unique. In this case, BP has trouble keeping the edge G2 continuous. This is wrong. I will work with the project team to find out where the problem is and how we can resolve it.

In the meantime, you could create multiple 3D Sketches (each has one curve segment). Then use Loft to create the surface. The result will be more satisfying. Interestingly, based on my personal experience, Loft and BP are sometimes interchangeable. When Loft does not work, BP can help vice versa. This is not the first case I see such behavior.

Many thanks!

Hi,

 

Sorry for the late reply. Yes, that is a tool that I tried beforehand. That is probably my best option. Thanks again!

Thanks for your help.

 

I didn't need that model, but an understanding on how to extrude from the face from a projected 2D sketch. When I do more complicated patterns, the technique from the video will be useful. Sorry that I said image. Sometimes, I be writing so fast, that I get my terminology off.

 

Thanks again!
