How can i draw a part from a picture sketch

[Haider66]

I wondered if there is a way to draw a 3d part from a pic sketch .
i did the method that import the picture then sketch it
but it doesn't accurate if i want to make an assembly part
check this pic

Create each part separately with sketch pictures then add them to an assembly. I hope this helps.

I did but the assembly was not justified
cause of the dimensional mismatch of each part

Was it designed with interference or deformation in mind? You may need to tweak the geometry so that everything can mate up in an as built geometry. I hope this helps.

how can i tweak the geometry ?
check this file plz how can i do it

You need to ZIP and post the part files as well as the assy file.

This is a zip file

You didn't put the PART FILEs in the zip, did you? The assembly file is just relations between the parts. Without the part files, the assembly is nothing & we can't open it. Please include the part files (looks like they are "f11.sldprt" and "Fd.sldprt"?) in your zip.

So sorry , this is the right one now

A picture is a picture - you can't use it too literally.

You should know one overriding basic size important to the design. Bring your picture into a sketch and scale to match that design parameter. Then model the parts relative to this picture (not absolutely reproduce). Multibody solids techniques would probably be the best way to model this so that you can easily build and check the relationships between parts. Then push out the assembly and individual parts when done.

I just opened your f11.sldprt and first thing I noticed is that your Sketch1 is not constrained or making use of symmetry about the X-Axis.

I think the first thing I would do is go through the built in Help>Tutorials. Otherwise this is just art - not engineering geometry that you can easily and predictably edit to get the parts to assembly correclty.

I had a project like that once, doing signs based on sketches.Success depended on getting all the sketches fully defined.
So is this a WWI aircraft model? You could probably laser cut from the jpegs, if you cleaned them up. We used to do that with Corel draw.

Thank you for replies
I brought the picture in the sketch and multiplied the width by the value (2.55/45) then i sketched it so that made it more accurate , but i had a problem in the assem
check it plz how can i exceed this

I'm doing this as a project too , It's Daddy-0 525 I don't know the original airplane but I think it's look like the Zero fighter

Kids today . . .
That is not a Zero, THIS is:

And jap-zero2.jpg what it's name isn't zero or i'm wrong ? kid
