Good evening - I'm a civil engineering student looking for some assistance with my first work placement sample project.
I've been given dimensions for a structure and asked to create a 3d model.
While I'm fine with 3d rendering, I'm not sure how to go about drawing the measurements I've been given.
One of the guys has drawn a draft up on Solidworks (which I need to take the data to produce what I need to input into CAD) I have attached it
Any help/pointers would be greatly appreciated! I think I'll be up all night pondering on this.
Pick an arbitrary point on your screen, I would use 0,0. Simply start drawing arcs from that point to the distances shown. You are given dimensions to establish the triangle so draw that as well. The horizontal line where the arc starts is where I would assume that the arc is tangent to the line, I think this is a safe assumption. Now draw the first 300 arc and where it crosses the first large arc you draw another 300 arc, where that crosses the second large arc you draw another 300 arc. Just a matter of placing one arc at a time.
Thanks! I've done that (or attempted to) but I'm still stuck at a standstill.
What I've done so far is plotted the two triangles with their values from a point (0,0). I've then drawn an arc between those two lines and just estimated the curve.
I can't seem to get the correct angles as I don't know the proceedure to work with.
So it sounds like you have the large and small arcs drawn.
One method would be to start the spline command and pick each intersection.
You could try drawing a few arcs, I am guessing this will work better. As a tip first draw a line from the left side of the horizontal line to the right side, be sure to use endp osnaps. Quit the line command, start the arc command, hit enter rather than picking anywhere. Now with Ortho off pull your cursor to the right to one of the intersections where the arc appears to change direction, keep moving the cursor and pick again to the right. If my assumption is correct the arc will hit those intersections.
