Extending an arc line

[Anonymous]

I have my first model almost done. it has been a heck of a learning experience, but I need some help to finish it. I need to take  a curved line and move one end 3mm and the other end 1 mm all while keeping the arc intact. I then need to complete it as a body and I should be good to go to move it to printing... I have tried everything that I can find in the available functions but the main thing is I cant use the arc function on the line I need to move. It will not snap to the points I need.

Hi,

Would you be able to post your design or record a screencast of what you are trying to do?

best regards,

Sanjay Jayabal.

Draw a circle on the end of the curve to extend with the extension radius, 3mm one end, 1 mm the other end.

use the Sketch > Extend Tool, on the curve to extend, will go to the circle, delete the circles.

Might help...

You want to extend part of the body, that is the shape of an arc, will need more information....

File > Export, to the hard drive and attach to another post, easier to answer with your data.

Might help...

Here is the file.

On the side shown in the screen shot. I need to drop the arc on the bottom by those dimensions to fit the other part. I need to do it to the whole part but since they are 2 different sections if I can so it to one then I can do it to the other separately.

Unconstrained sketches?

No History?

I recommend using what was learned in this attempt and start over.  (That is what I would have to do.)

It is a huge cluster and I dont even know what constrained means in relation to this type of stuff... I watched a lot of the video tutorials but they really didnt help me at all beyond the very basic stuff.

I prob should start over but it took me days to get here. Practice makes perfect... I hate that.

So - are you starting over, or are you still stuck?

Can you identify the body you wish to alter, in which component, 

can you then tell us which face, and which direction you wanted to alter, pics and descriptive views, bottom view?, the ones I have now, are not helping.  So far I have 4 bodies buried in those components.

I am a Timeline modeller, as I understand it, in DM you just keep adding features to the model you have now, but there is no editing of past activity, could be wrong....

Thanks to all for your responses. I just could not see redoing the whole thing... So I drew a bit by  bit line parallelish to the arc and found that I could us the arc function on the points of the lines i had drawn. So I was able to craw a close enough to the dimensions I needed. Used the sweep function to create the bodies and joined them to the model. So it is done. 

Thanks again. I learned a ton and will use it for the next model. Figure out how to not have so many components and sketches. 

Now to run it through nettfabb and see if I can print it out.
