Help needed to create a curved window frame

[fourleafclover]

Hey everyone

 

I am having trouble trying to make a curved window frame, I can't seem to think how I can offset or make a smaller version of the outline of the frame so that it can become a 3d solid.

 

Does anyone have any suggestions? thanks.

 

The picture seen below was created using the arc and polyline tool, autocad won't let me join these lines either!

It should work, I have no problem joining arcs and polylines together. What you need to do first though is convert the arc to a polyline (use pe), then after that use pe and join the polylines to create the closed polyline etc.

Did you create your profile in plan view?

Hi Dink, I have just converted all the current lines to polylines using as you suggested pe, but this still is not allowing me to join them up to become a closed polyline.

 

Do you think I am going the right way in order to create the curved window frame?

Hi ReMark, I am not too sure what you mean by this, could you explain please? What's a profile?

For some it might be all the lies and exaggerations they wrote when they posted the picture of that god-like being (who do you suppose it is?) on the online dating website. But in this case I would guess ReMark was thinking more along the lines of a "profile (think outline)" shape which will be used to sweep, loft or extrude the desired 3D model.

Hahaha, well if that is what was meant then I can say that the profile was created in plan view (I think)

If you are having difficulty converting existing lines, then don't. It sounds like you already have the lines, so now all you need to do is to create a new polyline by tracing over them with your osnaps turned on. That should get you your frame shape as a closed polyline. Offset the resulting polyline (use the polyline option when it is offered), by an appropriate amount and you will have 2 closed polylines. It sounds like you should probably set your system to retain your geometry/history ......... see the attachment for clues. You will access the options dialogue box by right clicking in your commandline, or at the bottom of your right click shortcuts menu. You might want to just make a copy of your starting lines too, move them out of your way, just so you know you still have them if anything untoward should happen.

Hey everyone

 

I am having trouble trying to make a curved window frame,

 

That looks trivially simple. Are you familiar with Loft? SolidEdit>Shell? Sweep?

Sculpt?

Can you attach the dwg file here?

[ReMark]

Did you try the PressPull command? Your lines don't have to be connected.

Did you try the PressPull command? Your lines don't have to be connected.

 

I have just attempted to use this method but it has not worked, autocad was asking me to select within bounded areas, which when I did select within the closed polylines it did not recognise these as a bounded area. Is a bounded area something else?

Hi JD, I am aware of these tools but have very little experience using them. I have attempted using them after seeing your post but have not managed to get anywhere with them.

 

Here is the file attached, I am trying to complete a house model. thanks

I do not know whether I have got everything turned on correctly, but when using the polyline draw tool should you be able to trace over curved arcs? When I try and trace over the current outline it does not allow me to. And thanks for the heads up over the geometry/history

[ReMark]

Simple lines and arcs should be all the geometry you need to create the profile of the curved window then either extrude or use press/pull. This whole exercise should take well under a minute to do.

I created this frame using some of the geometry that was in your drawing. I was able to extrude the two horizontal parts of the frame with no problem. For the two sides, I first changed the orientation of my UCS, then I used a 3Dpolyline to create a rectangle that I extruded. Finally, I unioned everything together. The width of the frame is 4.0 just like your other frames.

[fourleafclover]

I have got the frame to the first stage of extruding the two horizontal parts, so now I have aligned the UCS so that x is parallel with the vertical side and have created a 3d rectangle polyline, but now when I extrude this it is obviously straight and doesn't curve. I know this is really easy but I just can't seem to get my head around the curve!

[ReMark]

I did the same thing yet if you look at the image I had no problem with it when everything was unioned.
