How to draw a dinner table that is ellips but also has a rectangular part

Since yesterday I am trying to figure out how to make a (DXF) file that contains the right vector data of my dinner table with help of Onshape, but did not succeed yet.

Reason of this exercise is that I bought a plastic table cloth that is ellips shaped, this since I assumed my table is ellips. However, it does not fit. I contacted the online shop and shared photo's. They figured out that my table is indeed ellips shaped, but also has this rectangular middle piece that can be removed. So this middle removable part (of 57 cm lenght) is not ellips, but the rest of the table (two times 110 cm is, left and right of this middle piece, is). So, the entire lenght of the table is 277cm. The widht is 120 in the middle). Is it possibe to make this drawing with help of Onshape? The online shop asked for this DXF -file with the exact vector data this is how I 'discovered' this side.. Or should I use another tool to do so? Thanks in adavance for any feedback

    Is this what you meant? You should check the dimensions by editing the sketch 'half-sketch' and looking through the dimensions.


    If it is what you want: right click the top face of the table, then select "Export as DXF/DWG".

    You could sketch that out easily and even make it configurable via varaibles:

    It would be good practice to only ask a question ONCE in only one single discussion. I just saw there had already been an answer to this in another discussion posted the same day by the same user. People here haven't stolen their time, so ….
