![]() left to right, top to bottom, etc).įor example, draw a rectangle using the "Rectangle" tool on a grid set to orthoganal. I've gone back and experimented with the method in my original post and it seems the "Draw Ellipse Inscribed in a Quadrilateral" tool is sensitive to the order in which the four lines are selected and or the direction they are drawn in (i.e. So there should be a unique mathematical solution to an ellipse touching the midpoint of all four sides. All four sides are of equal length and each opposite pair of sides is parallel. Since the ellipse orientation and its major/minor radii are just 1/sqrt(2) of known values, the construction it quite straight forward.Īn isometric "square" is a four sided quadrilateral. type in relative coordinates to ellipse center: 50/sqrt(2) ![]() therefore, in command type in relative coordinates: 0ħ, type in coordinates for the end of minor axis: again, 1/sqrt(2) factor relative to vertex ( 200/sqrt(3), -50). or (0, 0), (100, 0), (100, 100), (0, 100) in 3D Ĥ, Draw -> Ellipse -> Center and two points ĥ, use command for center: ( 200/sqrt(3), 0), i.e., the rhombus center Ħ, set the end of major axis: which is 1/sqrt(2) to the rhombus vertex (400/sqrt(3), 0) which is relative to ellipse center ( 200/sqrt(3), 0). The basic idea is that: the projection to isometric does not change scale ratios in the same direction ( say, along a line before and after projection).Ġ, Edit -> Current Drawing Preferences-> Grid : choose isometricĢ, snap to grid only in the snap toolbar, no restrictionĤ, use command line (Ctl-M to activate or just click on the command line) to draw a square contour (square in 3D), i.e. You can use ellipse ( Center and two points, the first method in Draw -> Ellipse) together with command line (calculator) to get inscribed ellipse. Tools_instructions.pdf Last but not least, if you want to break your block back into the various original entities, select your block and click on the Explode tool in Modify.I didn't read carefully enough. I am working at the moment on an instruction document for all the drawing tools, it is not complete yet but I join here a PDF version of what exists: I suggest that you read the following document for more on that. If you want to save this block for future use you need to make sure you save it in the block list. Your block is created, now all the entities you selected are just one unit. Once you click on the point chosen a small window will open: "Block Settings", it will ask you for a Block Name, give it a name and OK it. Specify a reference point (you will need it if you copy it somewhere else). Once you have selected all the entities you need to join, select the tool "Create a Block", it looks like a rectangle with a circle in the lower left corner and a green point in the lower right. The problem here will be that I use a later version of LC: Version: 2.1.0-alphaįirst it does not matter if you are in isometric or not, LC is just a 2D CAD program. But it does not work! So I must have missed a step! ![]() I thought if you use Modify> move/copy, then click on the object and them move the mouse to a desired location and click again. How to you copy an object and then use a mouse to drop it at location pointed by mouse? There is no marker to show where to align the selected object with a desire drop location.ģ) Then I move the mouse pointer to the desire place.īut the position of the mouse pointer is not the position where the selected object is dropped.Ī) How do I joint all the parts into one object when in isometric mode?ī) The way I am doing the copy above is probably wrong and it is cumbersome. The selected objects (now a duplicate) turns white. I do not know how to joint all the objects into one object.ġ) I select with mouse all the objects by drawing a rectangle over the region.Īnd use the mouse to reselect the entire blue area. ![]() Then I like to click the object and it would select all the object.Īfter that I lie to copy and paste them at various locations with mouse. I like to group or join this objects into one. I have an ellipse with some lines and circle inside the ellipse in isometric drawing mode.
