I tried to design an ellipse with QCAD Tools - but I stuck .... maybe someone has an easy solution for me
Case: Imagine a model wall build with round dowels - like a Blockhouse,
Now I have to cut the top round dowels under 30° to get a gable shape,
In an isometric this cut has to appear like an ellipse on both sides,
Right side was easy to do with QCAD - maybe not absolutely correct but good enough
Left side .... a disaster I have no idea how I can make it correct looking
A square dowel shape is used as the construction base in the isometric.
I know how to design a correct ellipse step by step - that is not what I'm looking for! I'm looking for a fast and "just good enough looking" solution in QCAD!
Any Ideas?
How do I create an ellipse in an Isometric Projection ...

Hi Husky
Do you mean something like this ?

YES! Nice!!! How??? I'm to dummzumzum!
Re: How do I create an ellipse in an Isometric Projection ..
Well, ideally we need some additional options in the ellipse tools to produce something like this easily!
So... for me I didn't use the ellipse tool, I instead used the Spline (control points - sp) tool, which to be honest with an 'oblique' rectangle as you have here, is a lot easier to achieve something that resembles an elliptical shape.
This is how I done it - it's not straight forward but it does get the job done for now.
1.First make a grid.
2.Use the Spline tool (control points) and fit to the grid intersections.
3.Copy and paste the rest where you need them.

Nice, thanks a lot! The grid was the trick
Yep - that would be nice! But I'm sure - we have just to sit tight ...clive wrote:Well, ideally we need some additional options in the ellipse tools to produce something like this easily!

The new QCAD update - 3.2.1 - has a new tool what solves problems like this with just a few mouse-clicks. Perfect!!!
The new tool is called:
"Ellipse: Inscribed in quadrilateral (tangential to four lines) (EQ)"
You have to try it by yourself!

Yes what an excellant tool, I've been playing around with it...so very useful, especially for isometric work
Have you also noticed the extra Circle 'geometry' tools:

Yes I have - but the absolute winner for me is:clive wrote:Have you also noticed the extra Circle 'geometry' tools:
Modification tools: Clip selection to rectangular area.
Be a little creative, play in combination with this tool also with the clipboard and you can see how powerful this tool is!!!
