Snap points for lines are needed for me.
When working on a project that uses measurements smaller then the grid size, Shapr often begins a new line at a grid point… if the intersection of two lines, (to whitch a third is being added) is not at a snap point, it is difficult and time consumiong to confidently place a line (ray) endpoint where desired… If the end-of-line marker (the white dot used to edit and lock the lines); if this could change color when at the endpoint of a ray, or at the intersection of a two lines, my productivity, and confidence in line placement would be greatly improved. Although Google Sketchup uses a similar interface for lines (color changes to show placement), it fails when attempting to place a line near an intersection or midpoint. Sketchup will tend toward snapping to the marker, making it difficult in placing lines nearby.
A “marker snap” on/off toggle in Shapr3D would marry the two techniques for line placement nicely. When “marker snap off” then the line/ray point begins on the grid, when “marker snap on” the line snaps to the midpoint, end, or intersection. (I was thinking hold down toggle with thumb for snap to point on line, let go to snap to grid ).
Google Sketchup is a great tool for 3D modeling; more concentrated on building models line by line… where as, seems to me Shapr3D creates models shape by shape . Both have its merits, often line by line creates unwanted planes, and less clean of a finished model, shape by shape, has issues, such as creating simple shapes that would be easier to make with lines… such as a pyramid, or a hollow pyramid with a thin wall, or an angled and tapered plane.
I really enjoy Shapr3D, Have recommended it to my girlfriend, and others to use. It is great for the weekend, or novice CAD modeler, and outstanding that it is used on the IPad! Look forward to seeing what is new in upcoming releases.
Though I use an outdated Sketchup program, Shapr3D Blows Sketchup out of the water when it comes to modeling curves and complex shapes easily, such as the sphere. I look forward to purchasing Shapr3D when it can better compete with Sketchup’s interface.
