Problems with tesselation of line drawings - Polyloop

wasisn · 14th April 2004, 20:19

Hello everybody,

first of all I am glad that there is a English forum now, because my French is even worse than my English

I'm working with Designer 7.1 and have some trouble tesselating line drawings e.g. a rectangle or a triangle. I hope the attached files illustrate my problem but I will also explain it in words.

If I create a rectangle and afterwards use the 'middle segment tesselation' to tesselate each border with a range of 3, the left border isn't tesselated correctly. This could be seen, when using the stech tool and moving away two of the three new points (take a look at the images). The points on the left border seem to be messed up, they are not 1,2,3,4,5 but 1,4,3,2,5.

If I try to tesselate a triangle in the same way, the lower border has this problem (see the second image).

Is there a known solution for this problem?

Why do you need to do this?

yep i get the same result.

it doesnt seem to tesselate the 4th side properly :?

interesting :o

You're selecting all the sides at the same time when tesselating? Or doing one side at a time?

tried both Shonner same results :?

select all and select idividually and tesselate get the same thing

to answer Patrick this is a way to create uniform geometric profiles for extrutions etc i imagine using tesselate then selecting points and using the scale or move tools.

Tesselating (dividing of lines) only works on polylines, it seems. Not polygons. I tried it in Amapi 7 Pro. Note the open link.

It seems there is a bug in that case. I tried on Pro, and on the left segment, I cannot stretch the vertex with a constraint on the horizontal axis. With no constraint, it's ok. I don't have the case with the cross vertex

By the way, the good solution is to use the scale tool ;)
I'll submit this to Eovia

@Shonner:

Yes you are right. If I delete one side of the rectangle before I tesselate it, the remainig sides are tesselated correctly. Afterwards I can draw an new line to close the rectangle again, tesselate it and weld the two objects. This works but it is a bit complicated.

Did I get it right, that this problem also exists in A7P?

It happens in A7Pro, too.

Hello everybody,

I got some news from Eovia. They are going to fix this tesselation issue in the first patch for Amapi Pro. I just asked them wheter there will also be a fix for Amapi 7.1. I will post the answer when I recieve it.

The 7.15 patch for Amapi Pro fixes this problem.
