offset-tool bug

Recommended Posts

hi there,

i had a few probs with the offset-tool

composed a curve shaped polygon...used an inner offset and clipped the inner from the outer form. unfortunately the offsetted inner form isn t curvy anymore. it is just polyline and the accuracy of the curves is all gone.

i just figured out if i offset curves one by one and compose it later on. i get a curved form but it takes ages to do this.

thanks in advance

FYI, the Offset Tool was re-engineered in v12++.

By the way which Preferences> 2d resolution are you using ?

Doesn't work if one of the arc curve's tangent distance is > than 1/2 the distance between the intersection points (the VW midpoint).

I've recently noticed this same problem with this tool. It's not just the curved portions of the polygon that are irregular, but also throughout the entire offset, curved or not. It's a little difficult to tell in this format, but the 10' distance can vary as much as 6" throughout the offset from the original polygon, and sometimes the corners become smoothed...even the 90? corners. Here's an example of an inside 10? offset. Is this an instance of what you are referring to, Bruce? Please keep in mind that I went to public schools;-)

Oh yeah, the offset tool is not accurate. Just make a series of concentric ovals and watch them implode. When it's crucial I offset the lines and curves one at a time, which works. Then go through and trim each one to make the new set of lines. Huge pain.
