Hi,

How should I proceed to complete the half-frames of a sailing ship ?

I have the drawings of a old sailing ship that I want to build.

The drawing is a half frame, only the starboard (right) side.

How can I complete the frame along the vertical, center line, like a mirror.

Maintaining the same exact measurements.

Thanks in advance for your time,

Marc

Make a clone - mirror horizontally (press "H") - snap to point.

Sorry Polygon, but I didn't succeeded in completing the frames. Perhaps the drawing itself helps my explanation.

A picture will help.

What I want to do:

- Put all the half frames under each other.

- Mirror each frame along the vertical axis, so that I get a complete frame.

All this without losing the exact measurements.

TIA

You need duplicates for every parts of the image - draw clipping paths - clip away - duplicate - mirror - align:

Thanks Polygon, but I'm really a beginner !

How should I do that ? Draw a clipping path, clip away ?

1. Make a duplicate of the image

2. Draw a path around that portion that needs a mirrored companion 

3. select image +path and go Object->Clip->Set

4. Duplicate the result - hit "H" to mirror horizontally

5. Align with the other half - select both and "group"

6. start at 1. with the next part.

PS.: the image above is an Inkscape SVG by the way, download and check out.

Up to item 3 is ok.

But duplicate the result and mirror it, is a problem.

The clipped area is duplicated and mirrored, but without the actual frame. It's an empty area !

What am I doing wrong after x-times trying ?

Please download my example from above and reverse-engineer it. 

Thanks, I did that.

With your example I successfully drew complete frames.

Thanks for the help !

The only thing I still have, is that I can't exactly align the path with the center line.

Vriendelijke groeten,

Marc

I did this via arrow keys and when you need tiny increments with alt-key down.

But with enabled snapping to "cusp" nodes it will snap:

Thanks, for your invaluable help.

I've got the hang of it and already made several complete frames.

Hi Polygon,

Some 2 years ago you've helped me with the drawing of the frames of my ship.

But now I have to draw again some frames and I don't succeed.

1. Open the pdf file 

2. Save as a svg file

3. Duplicate the drawing 

4. Draw a path around the part that I need.

5. Object --> Duplicate --> Set 

And then I end up with a empty path.

Could you help (again) ?

What does the Status Bar tell about your selection before Object->Clip->Set?

Here is an attempt.

I used quite the same method as Polygon explained, with minor differences :

• I'v drawn all paths around frames (the future clipping paths), then selected bitmap and paths and used shapebuilder tool : with inkscape 1.4, it will creates clipped clones of image (decreasing file size).
• I used vertical guides then placed bitmap clipped images so that dashed middle line of image matches with guide. I dragged rotation point on guide (using snapping to guides and rotation centers). Eventually I did rotate clipped bitmaps a bit when dashed middle line of bitmap wasn't exaclty vertical, using the 3 pixels of width of this line on bitmap).
• With node tool (enable show clipping paths option) I place the left nodes of clipping paths (enable snapping to cusps nodes and guides) on guides : this way my clip is perfect on midlle dashed line.
• Once satisfied, I cloned the clipped image and reversed it and used snapping to rotation centers to place original and its clone exaclty.
