# Modifying the Geometry - HowTo ?

Genius

Hi all,

A very simple and basic question to the specialists:

I have an extruded triangle. It is placed within a square area of 500mm side width.

But to have it symmetric I would need the length of 184,62mm on the right side to be changed to 250mm.

I can access the two measures of 500mm, but I cannot access the 184,62mm.

What would be the simplest way to make the triangle symmetric with 250mm on the right side?

What would make the right hand side measure of 184,62 modifyable like the others?

best regards

Hans

Face relate horizontal/vertical is a way in sync. In ordered, a sketch.

So there is no way to access the the dimension and change it to 250?

Not sure why it's reference. Could you upload the model?

That the asm, are the par's also needed?

Hi @Hans11

my first and quick answer here would be, why using dimensions to get it symmetric.

use a symmetric relation to say: "Hi, triangle You are symmetric!"

This by the way is an old and long used procedere for me, independent wether or not You work synchrous or traditional.

Doesn't matter.

Always - and this is my suggestion to any new user and trainee I have with Solid Edge - always first try to make Your geometry good in the matter of geometrical quality, before concern the quantities, what are the dimensions.

A dimension is not the rigth tool to get it symmetric, You have geometrical relations to do so.

Another issue I immediateley have seen in Your video.

Why, if You want to have our geometry symmetric, why do You not use the coordinates system right from the beginning to use symmetric relations and even easier DesignIntends.

This would make the hole part that easy and flexibel, and this even with less dimensions and formulars.

Nevertheless, it also is no problem to do it with dimensions as You have tried it to do.

See video.

Hi Wolfgang

Thank You for creating the video. Unfortunately I can't see, as it is pic saying,

order cannot be executed

Your are right. Right from the beginning there would be better means to create it symmetric. But it was a bigger triangle placed on baseplatform. When I tried to minimize it, it became non symmetric and I tried to cure it with dimensions. But I came to the point, where I couldn't modify one of the dimensions, while I could modify the others.

By the way there are further issues I don't really understand. Thats the difference between the behaviour of lines and volumes. I can create a par containing a volume with lines on it. But if I import the par file, I only see the volume but not the lines, I would like to use for frames.

best regards

Oh just writing the last point, I found I have the set "lines on" in the asm-file.

Hi @Hans11

See it in above post!

Hi @Hans11

when You talk about "importing a part..." do You think about placing the part into an assembly or create a part copy into another part?

Both will work, but depending on the situation I have to give different answers.
