Hi, I am trying to draw the figure shown here using inkscape. I can create a cubiod/slab but I am not getting this view. I don't know how to rotate it. I guess rotation is not possible as it is only a 2D graphic software. How to draw the glass slab shown as here in inkscape? Please help.
This isn't Inkscape specific, I'm not an Inkscape user. Inkscape may have tools for "3D" which may be useful.
However, in general ... if one doesn't view things as being "3D" and thinks in terms of 2D objects .... The slabs are merely 3 rectangles, that's all.
One doesn't really need any "3d tools" to create such a thing.
You can use the 3D boxes tool X for this in Inkscape. Note that this isn't a true 3D tool, it can only create a 2D representation of a 3D box. Inkscape is 2D only.
Anyway, here's an example and the settings I used for the tool.
Here's a little explanation
set Angle X to 180, Angle Y to 270
depress all three parallel vanishing point buttons "II"
click and drag to draw a box
adjust Angle Z to tilt the slab up or down
The whole object is live, and you can adjust it as you like
Once you have done this, you can select the various pieces by using the Select by Nodes tool to select them, and apply different fill colours if required.
You can also turn the box into normal paths by doing Path > Object to path - which will bake in the effect, turning everything into separate objects.
Some auxiliary information:
Drawing 3D-like illustrations of laboratory experiments - even this simple and with no exact scale - is a lot of work if you need many of them and you for some reason cannot draw them manually in the traditional way.
Here's what you get in few minutes if you use a 3D program:
The glass plates are extruded rectangles and the cylinder is an extruded couple of circles. The particles are splitted spheres. That all is very fast and straightforward. Selecting non-fighting well visible colors and the right amount of transparency needs some experimenting.
In 3D you can rotate the view with no effort.
To stay in truth
- practicing and patient walking through some tutorials is a must. But it's the same if you are going to get something comparable drawn in Inkscape.
- inserting texts and other annotations is not easier in 3D. If you prepare them only for one view the effort is the same as in Inkscape. You can even do it in Inkscape.
- simple free 3D CAD programs cannot output the drawing as SVG or other vector image format except as a black&white wireframe. You'll get it easily in colors only as a bitmap. But that's a problem only if 100% vector drawing result is a must.
